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

True or False: An object with mass has gravity.

Back

True

Front

What two things determine the gravity of an object?

Back

Mass and distance.

Front

What is mass?

Back

Mass is the amount of matter in an object.

Front

Which statement about gravity is true?

Back

Gravity causes objects to pull towards one another.

Front

As mass increases, what happens to gravitational force?

Back

Gravitational force increases.

Front

What is weight?

Back

Weight is the force exerted by gravity on an object, calculated as mass times the acceleration due to gravity.

Front

How does distance affect gravity?

Back

As the distance between two objects increases, the gravitational force between them decreases.

Front

What is the formula for calculating weight?

Back

Weight = Mass x Gravitational Acceleration (W = m x g).

Front

What is gravitational acceleration on Earth?

Back

Approximately 9.81 m/s².
