8th Grade Force & Motion Unit

Front

What is force?

Back

A push or pull on an object that can cause it to accelerate.

Front

What is motion?

Back

The change in position of an object over time.

Front

What is velocity?

Back

The speed of an object in a specific direction, e.g., 40 m/s north.

Front

What is acceleration?

Back

The rate at which an object's velocity changes over time.

Front

What is net force?

Back

The overall force acting on an object when all the individual forces are combined.

Front

How do you calculate net force when forces are in the same direction?

Back

Add the forces together.

Front

How do you calculate net force when forces are in opposite directions?

Back

Subtract the smaller force from the larger force.

Front

What is the difference between speed and velocity?

Back

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

Front

What does a flat line on a distance-time graph represent?

Back

The object is not moving.

Front

What does a steeper slope on a distance-time graph indicate?

Back

The object is moving faster.
