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

What is mass?

Back

Mass is the amount of matter in an object, which does not change regardless of the object's location.

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 gravity change with distance?

Back

As the distance between two objects increases, the pull of gravity decreases.

Front

True or False: Gravity attracts all objects towards one another.

Back

True

Front

What is the relationship between mass and weight?

Back

Weight is directly proportional to mass; as mass increases, weight increases.

Front

What tool measures weight?

Back

A scale measures weight.

Front

What happens to an object's weight on the Moon compared to Earth?

Back

An object's weight on the Moon is less than its weight on Earth due to the Moon's weaker gravitational pull.

Front

What is the formula for calculating weight?

Back

Weight = Mass x Acceleration due to gravity (W = m x g).

Front

What is the acceleration due to gravity on Earth?

Back

The acceleration due to gravity on Earth is approximately 9.81 m/s².
