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 does mass measure?

Back

Mass measures the amount of matter in an object, typically in kilograms or grams.

Front

How does distance affect gravity?

Back

The farther apart two objects are, the weaker their gravitational attraction.

Front

What holds the planets in orbit around the sun?

Back

Gravity holds all of the planets in orbit around the sun.

Front

True or False: Any object with mass has gravity.

Back

True.

Front

What is the relationship between mass and gravitational force?

Back

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

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

What is the formula for calculating weight?

Back

Weight = Mass x Gravity (W = m x g).

Front

What is the gravitational force on Earth?

Back

The gravitational force on Earth is approximately 9.81 m/s².

Front

What happens to gravity in space?

Back

Gravity still exists in space, but it decreases with distance from massive objects.
