Every action has an equal and opposite reaction.

Front

What is Newton's Third Law?

Back

4 m/s2

Front

A force of 20 N acts upon a 5 kg block. Calculate the acceleration of the object

Back

Force = Mass x Acceleration.

Front

What is Newton's Second Law?

Back

Front

A 1000 kg car accelerates from rest to 5m/s in 2.5 seconds. How much force does the car produce?

Back

2.5 m/s2

Front

A car with a mass of 2000 kg goes from 40m/s to a stop in 4 seconds. What force was exerted to stop the car?

Back

2 N

Front
