Gravity, Mass & Weight

Front

What is gravity?

Back

Gravity is a force that attracts two bodies towards each other, commonly experienced as the force that pulls objects towards the Earth.

Front

What is mass?

Back

Mass is the amount of matter in an object, usually measured in kilograms or grams.

Front

What is weight?

Back

Weight is the measure of the force of gravity acting on an object, typically measured in Newtons.

Front

How does weight change with location?

Back

Weight can change depending on the strength of the gravitational pull at different locations, such as on different planets.

Front

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion; an object at rest stays at rest, and an object in motion stays in motion unless acted upon by a force.

Front

What unit is weight measured in?

Back

Weight is measured in Newtons (N).

Front

Which planet has the least amount of mass?

Back

Mercury has the least amount of mass among the planets listed.

Front

What happens to gravity if mass increases?

Back

If the mass of an object increases, the gravitational force it exerts also increases.

Front

What is the relationship between mass and weight?

Back

Weight is directly proportional to mass; as mass increases, weight increases, assuming the gravitational pull remains constant.

Front

Can weight be the same on different planets?

Back

No, weight varies on different planets due to differences in gravitational pull.
