Gravity

Front

What is gravity?

Back

Gravity is a force that attracts two bodies towards each other, 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, attracting it towards the ground.

Front

What is weight?

Back

Weight is the force of gravity acting on an object, which depends on the object's mass and the gravitational pull of the planet.

Front

Why would a person weigh more on Jupiter than on Earth?

Back

Because Jupiter has more mass, resulting in greater gravity.

Front

Why would a person weigh less on the Moon than on Earth?

Back

Because the Moon has less mass and therefore less gravity.

Front

What happens to the force of gravity when the distance between two objects increases?

Back

The force of gravity decreases as the distance between the two objects increases.

Front

What is the relationship between mass and gravity?

Back

The greater the mass of an object, the stronger its gravitational pull.

Front

When are the forces of gravity between two objects the greatest?

Back

When the masses of both objects are large and the objects are close together.

Front

What is the formula for calculating weight?

Back

Weight = mass × gravitational acceleration (W = m × g).

Front

How does gravity affect the motion of planets?

Back

Gravity keeps planets in orbit around stars, such as the Earth orbiting the Sun.
