What is the law of conservation of Energy?
For every action there is an equal and opposite reaction.
Energy cannot be created or destroyed, only transformed
There is only KE and PE

What is Newton's first law of motion?
For every action there is an equal and opposite reaction
Force is a measurement of Mass and Acceleration
An object at rest will remain at rest, an object in motion will remain in motion
What is Newton's Second law of motion?
For every action there is an equal and opposite reaction
Force is a measurement of Mass x Acceleration
An object at rest will remain at rest, an object in motion will remain in motion
What is Newton's Third law of motion?
For every action there is an equal and opposite reaction
Force is a measurement of Mass x Acceleration
An object at rest will remain at rest, an object in motion will remain in motion
How do you keep an objects acceleration the same if the force is doubled?
Double the mass
Cut the mass in half
quadruple the mass
square the mass

What is momentum and why do you need to give more distance between cars that are traveling faster?
The quantity of motion in an object/ faster speeds take longer to slow down
The amount of inertia in an object/ faster objects take longer to slow down.
The quantity of motion in an object/ faster objects are quicker to slow down.
