Unit 4 - 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 position of an object over time.

Front

What is speed?

Back

The distance traveled per unit of time, usually measured in miles per hour (mph) or meters per second (m/s).

Front

What is average speed?

Back

The total distance traveled divided by the total time taken.

Front

What is a balanced force?

Back

Forces that are equal in size but opposite in direction, resulting in no change in motion.

Front

What is an unbalanced force?

Back

Forces that are not equal, causing a change in the motion of an object.

Front

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

Back

An object that is not moving (at rest).

Front

What does a straight diagonal line on a distance-time graph represent?

Back

An object moving at a constant speed.

Front

How do you calculate average speed?

Back

Average Speed = Total Distance / Total Time.

Front

What is the formula for calculating force?

Back

Force = Mass x Acceleration (F = m x a).
