## How does weight depend on mass?

Mass is independent of gravity and is therefore different from weight. … The force with which an object near the Earth or another celestial body is attracted toward the center of the body by gravity. An object’s weight depends on its mass (the amount of matter it consists of) and the strength of the gravitational pull.

## What is the relationship between weight and mass?

We know that weight is equal to the product of mass and gravitational force applied. So, W = MG where w is the weight, M is the mass, and G the gravitational force. Hence, it can also be interpreted as ‘the weight of an object is directly proportional to its mass’.

## How is weight affected by mass and gravity?

Weight refers to the gravity force of planets and other bodies in the Universe, and the effect that this has on objects. … This means that for a given gravitational field strength, the greater the mass of the object, the greater its weight. Weight is a non-contact force because gravity exerts its force through a field.

## Can mass be equal to weight?

the values for mass and weight are the same. If you change your location with respect to gravity, mass will remain unchanged, but weight will not. For example, your body’s mass is a set value, but your weight is different on the Moon compared with on Earth. Mass is a property of matter.

## Why do scientists use mass instead of weight?

Why Mass Is More Useful for Measuring Matter Than Weight

Mass is a consistent measure of the amount of matter, but weight isn’t. Mass also creates the gravitational force that defines weight, which is why it appears in the equation for weight.

## How is mass and weight different?

The mass is essentially “how much stuff” is in an object. … Weight: There is a gravitational interaction between objects that have mass. If you consider an object interacting with the Earth, this force is called the weight. The unit for weight is the Newton (same as for any other force).

## Why does weight of matter change while its mass does not?

Weight is a measure of how strongly gravity pulls on that matter. Thus if you were to travel to the moon your weight would change because the pull of gravity is weaker there than on Earth but, your mass would stay the same because you are still made up of the same amount of matter. … The amount of that force is weight.

## How do you get weight from mass?

Summary
1. Weight is a measure of the force of gravity pulling down on an object. It depends on the object’s mass and the acceleration due to gravity, which is 9.8 m/s2 on Earth.
2. The formula for calculating weight is F = m × 9.8 m/s2, where F is the object’s weight in Newtons (N) and m is the object’s mass in kilograms.

## What are three differences between mass and weight?

Difference between Mass and Weight is Mass is a measure of Inertia and Weight is a measure of Force. Many often tend to use these two terms in the same manner. However, this is not correct at all.

Difference between Mass and Weight.
Basis of Comparison Mass Weight
Gravitational Effect It can never be zero. It can be zero when no gravity is acting on it.

## Can a body have mass but no weight?

Yes, a body can have mass but still no weight. Weight W = mg, where m is the mass of the body and g the acceleration due to gravity. … g = 0 at the centre of the earth and in space. In those locations where g = 0, weight = 0.

## How do you explain mass and weight to a child?

A simple weight definition for kids is: weight refers to the force gravity applies to an object. A simple mass definition for kids is: mass reflects the amount of matter (i.e., electrons, protons and neutrons) an object contains. We can place a scale on the moon and weigh an object there.

## What is the mass of a girl who weighs 450 N?

So mass of the girl (m) = 450/9.8 = 45.9 kg.

## Is mass weight or volume?

Mass is the amount of matter an object contains, while volume is how much space it takes up. Example: A bowling ball and a basketball are about the same volume as each other, but the bowling ball has much more mass. To be precise when using measurement terms, make sure you know the difference between mass and weight.

## Can there be forces acting on an object at rest?

If an object is at rest, then there are no forces acting upon the object. It would take an unbalanced force to keep an object in motion at a constant velocity.

## How much does a 100 kg astronaut weigh on Earth?

So, a 100 kg astronaut weighs 980N on Earth. On the Moon, the astronaut would weigh only 162.2N.

## How much mass is 400n?

400 N is ~ 40 kg on the surface of the earth (with g ~ 10 m/s^2). This is approximately 88 pounds. So someone who weighs 88 lbs exert a force on the ground equivalent to 400 N.

## Can there be forces acting on an object if the object is at rest must there be an unbalanced force?

There can be forces acting on an object if the object is at rest like gravity. … There must be an unbalanced force acting on a moving object because if the object would not move then it is a balanced force.
