Gravity

Front

What is gravity?

Back

Gravity is a force that attracts two bodies towards each other, with the strength of the attraction depending on their masses and the distance between them.

Front

Why does a ball fall to the ground?

Back

Because Earth's force of gravity is GREATER than the ball's, so the ball gets attracted to the ground.

Front

What holds all of the planets in orbit around the sun?

Back

Gravity.

Front

What is the difference between weight and mass?

Back

Weight is the force of gravity acting on an object, while mass is the amount of matter in an object.

Front

How does gravity affect weight on the Moon compared to Earth?

Back

A person would weigh less on the Moon than on Earth because the Moon has less mass and therefore less gravity.

Front

What is the formula for calculating weight?

Back

Weight = mass × gravity.

Front

What is the gravitational force between two objects dependent on?

Back

The gravitational force depends on the masses of the objects and the distance between them.

Front

What happens to the gravitational force if the distance between two objects increases?

Back

The gravitational force decreases as the distance between the two objects increases.

Front

What is the gravitational pull of the Earth?

Back

The gravitational pull of the Earth is approximately 9.81 m/s².

Front

What is an example of a force that opposes gravity?

Back

Air resistance is an example of a force that opposes gravity.
