Question 8

Newton 2nd law

Answer 8

Force = mass * acceleration

Question 9

Newton’s 3rd law

Answer 9

For every action there is an equal but opposite reaction.

Question 10

Inertia

Answer 10

The tendency of an object to resist being moved or , if the object is moving, to resist a change in speed or direction until an outside force acts in the object.

Question 11

Answer 11

A force that resists motion.

Question 12
