Unit 2: Lesson 4 (Gravity)

Front

What is gravity?

Back

Gravity is a force that pulls objects toward each other, such as the Earth pulling objects toward its center.

Front

What happens to a baseball when it is thrown into the air?

Back

It comes down due to gravity pulling it down.

Front

What are the two main factors that affect the force of gravity between two objects?

Back

Mass and Distance.

Front

Why do objects weigh less on the Moon than on Earth?

Back

The Moon has less mass and therefore less gravity.

Front

When is the force 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 relationship between mass and gravity?

Back

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

Front

How does distance affect gravitational force?

Back

The greater the distance between two objects, the weaker the gravitational force between them.

Front

What is the effect of gravity on falling objects?

Back

Gravity causes falling objects to accelerate towards the ground.

Front

What is the difference between weight and mass?

Back

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

Front

What would happen to gravity if the Earth were to double its mass?

Back

The gravitational force would increase.
