Q.
the energy an object has because of its motion
2
20 sec
Q.
energy that an object has because of its motion or its position (kinetic or potential energy - the object must be able to move)
3
20 sec
Q.
energy in the form of heat
4

Q.
the energy that is stored in the bonds between atoms
5

Q.
A closed loop through which electrons can continuously flow from a current source.
6

Q.
Energy cannot be created out of nothing, nor can it be completely destroyed. Energy can only change its form.
7

Q.
a force that opposes the motion of a body across a surface or through a gas or liquid
8

Q.
distance traveled per unit of time
9

Q.
the speed and direction of moving objects
10
30 sec
Q.
a force of attraction that exists between any two objects that have mass
11
20 sec
Q.
a object's change in speed or direction (or a change in velocity)
12
30 sec
Q.
an object's resistance to change (Objects in motion tend to stay in motion, and objects at rest tend to stay at rest until acted upon by another, greater force.)
13

Q.
the invisible area surrounding a magnet that causes magnets to exert force over a distance
14

Q.
regions where a magnet is strongest that line up with Earth's magnetic north-south axis
15

Q.
to move away or force back (as when matching N and N in a bar magnet)
16

Q.
one of six basic devices that help do work by changing the direction, amount, or distance of a force
17

Q.
two or more simple machines working together (such as a bicycle, sissors, or a wheel barrow)
18
20 sec
Q.
how much a machine changes the input force needed to do work (= output force/input force)
19

Q.
a bar or plank that pivots at a fixed point called the fulcrum
20

Q.
What is the simple machine in the image?
21

Q.
a wheel overlaid with a rope to change the direction of the pull used for lifting a load
22

Q.
a ramp or even sloping surface that connects an object at one height to an object at another height
23

Q.
an inclined plane wrapped around a central shaft with a wedge at the tip used to bind objects together
24
20 sec
Q.
two or more inclined planes joined together at a point to raise or push things apart
