Front

How do you find average speed?

Back

Average speed= Total distance

Total Time

Front

Negative acceleration is also known as?

Back

Deceleration

Front

What is Acceleration?

Back

Rate at which velocity changes

Front

What formula would you use to find acceleration?

Back

Acceleration= Final Speed-Initial Speed

Time

Front

Distance?

Back

Distance= Velocity X Time

Front

What are the two factors that affect the friction force between 2 surfaces?

Back

The type of surface and how hard the surface is.

Front

What is the acceleration due to gravity here on Earth? Why do some objects fall though the air at a different rates than others on Earth?

Back

9.8 m/s^2.

Air resistance.

Front

How does mass differ from weight?

Back

Mass is the total amount of matter in an object. Weight is the force of gravity on an object.
