Answers
Question: speed
Answer:
the rate at which an object travels; determined by dividing the distance by the amount of time the
object
takes to travel that distance

Question: potential energy
Answer:
stored energy

Question: kinetic energy
Answer:
energy due to motion

Question: mechanical energy
Answer:
ability to make something move

Question: distance
Answer:
the amount of space traveled from where an object starts to where it is at any given moment.

Question: velocity
Answer:
the distance an object moves over a given amount of time in a certain direction

Question: acceleration
Answer:

or changes direction

Question: friction
Answer:
a force that keeps objects from moving against other objects

, Question: momentum
Answer:
the mass and velocity of an object

Question: inertia
Answer:
resistance to a change in motion

Question: first law of motion
Answer:
says that an object tends to stay at the same velocity unless another force causes it
to change

Question: gravity
Answer:
the pull of one object on another

Question: second law of motion
Answer:
states that force is equal to an object's mass and the acceleration of the object

Question: third law of motion
Answer:
When one object exerts a force on another object, the second object reacts by
exerting an equal force back on the first object
