Question

True or False: For every action, there is an equal or opposite reaction. This

is Newton's 3rd law of Motion. *
True
False

Answer 1

Answer: True

Newton's first law talks about inertia. Specifically an object at rest will stay at rest, while an object in motion will stay in motion. This only changes when a new force is applied to either speed up the object up, slow it down, or bring it to a stop.

Newton's second law is the idea that mass times acceleration is the force applied. So it talks about the equation F = ma. The more mass you're dealing with, the more force is needed to accelerate it to the target speed.

The third law is the idea where if you push on something, then it will push back with the same amount of force. This principle is what allows rockets to maneuver in the vacuum of space. Essentially fuel is burned and ejected out of the end of the rocket, which in turns pushes it forward. The force pushing the stuff out the backend is the same amount pushing it forward.

Answer 2

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

This is false

The true is:

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