Hooke's Law is when an elastic object is stretched. Equation: F = K x E

What are "Vectors and Scalars?"
Scalars are quantities that are fully described by a magnitude alone. Vectors are quantities that are fully described by both a magnitude and a direction.

What is the difference between "Levers" and "Gears"?
A lever is the simpliest type of mechanism (one job), whereas gears do several jobs.

What is a "Moment" in Science?
A "Moment" is the turning effect of a force around a fixed point: this is called a pivot.

Name some forces that would act on a vehicle as it travels.
Weigh, Reaction Force, Driving Force, Friction, Air Resistance.
5 of 10
The difference between "Contact" and "Noncontact" forces?
Contact forces physically touch the object: however noncontact forces doesn't make contact with an object (for example: weight).

What is a "Resultant Force"?
Something that has the same effect on the object as all the individual forces acting together.
7 of 10
What is the difference between "Mass" and "Weight"?
Mass is a measurement of the amount of matter something has: whereas weight is the measurement of the pull of gravity an object has.
8 of 10
What is the definition of "workdone"?
The amount of work produced by a force, which depends on the size of the force and the distance it moves.

What's "Elastic Potential Energy"?
Elastic potential energy is potential energy stored as a result of deformation of an elastic object
