# Do all objects have the same mass?

## Do all objects have the same mass?

On earth, all objects (whether an elephant or a feather) have the same force of gravity. The elephant weighs more than the feather, yet they each have the same mass. The elephant clearly has more mass than the feather, yet they each weigh the same.

**What does it mean when two objects have the same mass?**

Density is known as the amount of substance present in a liter. Whereas mass present in a substance means the amount of matter present in it. Hence, we can conclude that if two objects have the same mass, then it is true that they contain the same amount of matter.

**Will 2 objects with the same mass have the same momentum?**

Momentum is not equal to the mass of an object divided by its velocity. Two objects with the same mass will always have the same momentum.

### How can objects weigh the same but be different sizes?

Answer. Answer: Assuming that, the difference between two objects of different weights but of the same volume is density, which is measure as mass per unit volume. It comes from the atomic weight of the atoms composing an object and how closely packed is the material composing that object.

**What is meant if an object was made smaller than the actual size as in the size of object?**

A scale model is a representation or copy of an object that is larger or smaller than the actual size of the object being represented. Very often the scale model is smaller than the original and used as a guide to making the object in full size.

**Why do objects vary in looks and sizes?**

When we view an object from different distances, the size of its projection onto the retina changes: the retinal image becomes larger when an object is located at a nearer position and becomes smaller when the object is located at a distant position.

#### Why do further objects look smaller?

When things are closer to you, they take up more of your field of view, so they seem bigger. When they’re further away, they take up less of your field of view, and so seem smaller. One way to measure our field of view is to use an angle. The further away the object is, the smaller this angle will be.

**Do larger objects always have more mass?**

The expectation that a larger object will feel heavy is presumably caused by the fact that larger objects generally contain more material and consequently have a larger mass than smaller objects. When, in contrast, the two objects have the same mass, an illusory heaviness difference occurs.

**How heavy an object is for its size is its?**

1 Density Density describes how heavy an object is compared to its size. 3 Volume – two options Volume is how much space an object takes up.

## What is the difference between mass and volume?

Mass is how much stuff something is made of. Volume is how much space an object takes up. Find two objects with similar MASS.

**What is difference mass and weight?**

Your mass is the same no matter where you go in the universe; your weight, on the other hand, changes from place to place. Mass is measured in kilograms; even though we usually talk about weight in kilograms, strictly speaking it should be measured in newtons, the units of force.

**Is KG a weight or a mass?**

Because mass and weight are separate quantities, they have different units of measure. In the International System of Units (SI), the kilogram is the basic unit of mass, and the newton is the basic unit of force. The non-SI kilogram-force is also a unit of force typically used in the measure of weight.

### How mass is calculated?

Divide the object’s weight by the acceleration of gravity to find the mass. You’ll need to convert the weight units to Newtons. For example, 1 kg = 9.807 N. If you’re measuring the mass of an object on Earth, divide the weight in Newtons by the acceleration of gravity on Earth (9.8 meters/second2) to get mass.

**What is the relationship between weight and mass?**

Mass is the quantity of matter in a substance. The weight of an object is the net force on a falling object, or its gravitational force. The object experiences acceleration due to gravity. Some upward resistance force from the air acts on all falling objects on Earth, so they can never truly be in free fall.

**What is an example of mass and weight?**

A: Mass is a measure of all the matter that makes up an object, and weight how much gravity is acting upon an object. Since we’re on Earth and used to measuring things on Earth with Earth’s gravity, if your mass is 50 kg, we say that you weigh 50kg. A scale on Earth would read 50kg, or 110lbs.

#### Does matter have mass?

In classical physics and general chemistry, matter is any substance that has mass and takes up space by having volume.

**What is your mass on Earth?**

On the Moon, the astronaut would weigh only 162.2N. However, the astronaut’s mass is 100kg where-ever they are. Weight on Earth: 100kg x 9.8m/s2 = 980N.

**Can a body has mass but no weight?**

It is denoted as g. Now for different planets the value of acceleration due to gravity is different. So, for a body to have no weight, the acceleration due gravity must be zero. Hence, it is possible that a body can have mass but no weight.

## How do you convert force to mass?

Divide the newtons by the rate of acceleration, which will give you the mass of the object. The mass will be in kilograms, because a single newton represents the amount of force needed to move one kilogram one meter. For our example, we will divide 10 N by 2 m/s/s, which give us a mass of 5 kg.

**What are the two masses and the one distance that determine your weight?**

What are the two masses and the one distance that determine your weight? Mass of you, mass of Earth, and the distance between the center’s of gravity. In what way is gravity reduced with distance from Earth? By the inverse of the square of the distance.

**What would happen to your weight if your mass doubled?**

Doubling the mass of the Earth would double your weight, since gravitational force is directly proportional to mass, but doubling the radius (which doubles if the diameter doubles) would decrease your weight by a factor of 1/4, since gravitational force is inversely proportional to the square of the radius.

### How does the force of gravitation between two objects?

According to the law of gravitation, the force of attraction acting between two bodies is given by, Thus, when the distance between the objects is reduced to half the gravitational force increases by four times the original force.

**Why do masses attract each other?**

Since the gravitational force is directly proportional to the mass of both interacting objects, more massive objects will attract each other with a greater gravitational force. So as the mass of either object increases, the force of gravitational attraction between them also increases.

**What makes a gravitational force noticeable?**

Unless someone is taking very precise measurements in a lab (see for example Cavendish’s famous experiment which determined the gravitational constant, G), the force of gravity must include only really big objects (like the sun, the moon or a planet) to be noticeable.

#### What causes objects to attract?

Electromagnetism causes like-charged objects to repel each other and oppositely charged objects to attract each other. Any object with mass exerts a gravitational pull on any other object with mass. You don’t fly off Earth’s surface because Earth has a gravitational pull on you.

**What happens to the force of attraction between two objects when their masses are halved?**

Answer. Thus, force becomes one-fourth as we reduce the masses to half without altering the distances.

**What happens to the force of attraction between two objects a when their mass are halved B distance between them is increased to 4 times c distance between them and each of their mass is increased to 4 times?**

Describe how the gravitational force between two objects depends on the distance between them. Therefore, as the distance between the two bodies is doubled, the gravitational force becomes one-fourth and when the distance is halved, the gravitational between these two bodies becomes four times.

## In what source is G universal?

G is known as universal constant because it is equal through out the universe. Its value doesn’t change . That is the force of gravitation is directly proportional to the masses of two bodies and inversely proportional to the square of distance between them.

**What happens to the force of attraction between two objects when I their mass are halved II distance between them is increased to 4 times its previous value III distance between them as well as each of the mass is increase to 4 times?**

Therefore when the distance between the objects is reduced to half, then the force of gravitation increases by four times the original force. Gravitational force acts on all objects in proportion to their masses.
