MOTION chapter 13

Front

What is average speed?

Back

Average speed is the total distance traveled divided by the total time taken. It is measured in meters per second (m/s).

Front

How do you calculate average speed?

Back

Average speed = Total Distance / Total Time.

Front

What is deceleration?

Back

Deceleration is the rate at which an object slows down. It is a negative acceleration.

Front

What does a negative acceleration indicate?

Back

A negative acceleration indicates that an object is slowing down.

Front

What is Newton's First Law of Motion?

Back

An object at rest stays at rest, and an object in motion stays in motion unless acted upon by an unbalanced force.

Front

What is Newton's Second Law of Motion?

Back

Force = Mass x Acceleration.

Front

What is Newton's Third Law of Motion?

Back

For every action, there is an equal and opposite reaction.

Front

How do you calculate acceleration?

Back

Acceleration = (Final Velocity - Initial Velocity) / Time.

Front

If a bike speeds up from 10 m/s to 60 m/s in 5 seconds, what is its acceleration?

Back

10 m/s/s.

Front

If a bird accelerates from 15 m/s to 50 m/s in 7 seconds, what is its acceleration?

Back

5 m/s/s.
