|
What is motion, rest, and outside force
Fill in the blank: An object in _________ will stay in motion/An object at ________ will stay at rest, unless acted upon by an _________ ___________.
|
What is Newton's Third Law
A rocket's action is to push down on the ground with the force of its powerful engines. The reaction is that the ground pushes the rocket upwards with an equal force, but opposite in direction.
|
1st: An object at rest will stay at rest/ an object in motion will stay in motion, unless acted upon by an outside force.
2nd: The force of an object can be found by multiplying its mass times its acceleration 3rd: For every action, there is an equal and opposite reaction.
