1
Q

work

A

the transfer of mechanical energy between two objects that exert force on each other (J)

2
Q

energy

A

the ability of an object to do work on another object (J)

3
Q

mechanical energy

A

the amount of work an object can do because of the object’s kinetic and potential energy’s (J)

4
Q

power

A

the rate at which work is done by a force per unit time (J/S)

5
Q

simple machines

A

basic machine, basis for all other machines

6
Q

work input

A

total work, bigger number bottom (J)

7
Q

work output

A

remaining energy left, smaller number on top (J)

8
Q

complex machines

A

machine made or more than one simple machine

9
Q

kinetic energy

A

energy due to motion (J)

10
Q

potential energy

A

energy of an object based on its potential for movement(J)

11
Q

gravitational pe

A

object with potential for movement due to its height above surface of earth (J)

12
Q

Law of Conservation of Energy

A

energy can be neither created nor destroyed only transferred

13
Q

work-energy principle

A

total work done on an object by a net force equals the change in the object’s kinetic energy
