Answer: work =force x distance
⩥ What is the unit for work?
Answer: Joule (J)
⩥ What is power?
Answer: The rate at which work is done
⩥ What is the equation of power?
Answer: power=work done/time interval
⩥ What is the unit for power?
,Answer: Watt (W)
⩥ What is energy?
Answer: The "something" that enables an object to do work. (measured
in J)
⩥ What is mechanical energy?
Answer: The energy due to the position of something, or the movement
of something
⩥ What is potential energy?
Answer: Energy that is stored
⩥ What is gravitational potential energy?
Answer: The potential energy due to the elevated positions, Energy
stored in the system as a result of a gravitational force between the
object and Earth
⩥ What is the equation for gravitational potential energy?
Answer: gravitational potential energy=weight x height

Answer: PE = (m)(g)(h)
, ⩥ Law if Conservation of Energy
Answer: The study of the various forms of energy and the
transformations from one form into another
⩥ Machine
Answer: A device used to multiply forces or simply to change the
direction of forces
⩥ Lever
Answer: a macine that is made of a bar that turns about a fixed point
EX: pushed down then the lever is lifted up
⩥ Fulcrum
Answer: pivot point
⩥ Mechanical Advantage
Answer: The ratio of output force to input force for a machine
⩥ What are three common ways to set up a lever?
Answer: 1. The fulcrum is between the force and the load.
EX: Seesaw
