Force and Motion

Front

What is force?

Back

A push or pull on an object that can cause it to move, stop, or change direction.

Front

What is motion?

Back

The change in an object's position over time.

Front

What is gravity?

Back

A force that pulls objects toward each other, such as the Earth pulling us down.

Front

What happens to an object's motion when a force is applied?

Back

The object's motion changes; it can speed up, slow down, or change direction.

Front

What is mass?

Back

The amount of matter in an object, which affects how much force is needed to move it.

Front

What is relative motion?

Back

The change in position of one object compared to another object.

Front

What is inertia?

Back

The tendency of an object to resist changes in its state of motion.

Front

How does increasing mass affect gravity?

Back

As an object's mass increases, the gravitational force it exerts also increases.

Front

What is a reference point?

Back

A stationary object used to determine the position of another object.

Front

What is the difference between speed and velocity?

Back

Speed is how fast an object moves, while velocity includes direction.
