Front 4

___ = W
____
T

Back 4

P (Power = Work
______
time

Front 5

F = M x ____

Back 5

A (Force = Mass x Acceleration)

Front 6

____
?

Back 6

M Acceleration = Force
_______

Front 7

M = F
_____
?

Back 7

A Mass = Force
______
Acceleration

Front 8

Describe Newton's 1st Law of Motion

Back 8

An object at rest, remains at rest and an object in motion remains in motion; unless acted upon by an outside force. Give example

Front 9

Describe Newton's 2nd Law of Motion

Back 9

The acceleration of an object depends on the mass of the object and the amount of force applied. Give example

Front 10

Describe Newton's 3rd Law of Motion

Back 10

For every action there is an equal and opposite reaction.
Give example

Front 11

Friction

Back 11

Friction occurs because the surface of any object is rough. When the hills and valleys of one surgace stick to the hills and valleys of another, friction is created. Rougher surfaces create more friction.

Front 12

Gravity

Back 12

Gravity is a force of attraction between objects that is due to their masses.

Front 13

What it means to work

Back 13

To get a job done using energy.(work occurs when a force causes an object to move in the direction of the force) Example throwing a ball
- work is done on an object only when force makes that object move.

Front 14

Examples of simple machines and why they help make work better.

Back 14

They make work easier - lever, inclined plane, wedge, screw, wheel & axle, pulley

Front 15

List examples of each -
lever, inclined plane, wedge, screw, wheel and axle, pulley

Back 15

lever - screwdriver, end of hammer to remove a nail, inclined plane - ramp, wedge - knife, screw - screw, wheel and axle- door knob, pulley - cord on window blind.

Front 16

Force

Back 16

a push or a pull. All forces have both size and direction. Scientist express force using a unit called the newton (n) The more newtons the greater the force.

Front 17

Work

Back 17

The action that results when a force causes an object to move in the direction of the force.

Front 18

lever

Back 18

A simple machine consisting of a bar that pivots at a fixed point, called a fulcrum. There are 3 classes of levers.

Front 19

M/S/S

Back 19

Acceleration is expressed in meters per second per second

Front 20

Joule

Back 20

The unit used to express work and energy equivalent to the newton-meter.

Front 21

Speed

Back 21

The rate at which an object moves. Speed depends on the distance traveled and the time taken to travel that distance.
Average Speed = Total distance
______________
Total time

Front 22

Newton

Back 22

Scientists express force using a unit called Newton(N) the SI unit of force

Front 23

Screw

Back 23

A light bulb

Front 24

Acceleration

Back 24

is the rate at which velocity changes
Acceleration = final velocity-starting velocity divided by time it takes to change velocity.

Front 25

Watts

Back 25

(W)The unit used to express power; equivalent to joules per second (j/s)

Front 26

Wheel and axle

Back 26

a simple machine consisting of two circular objects of different sizes; the wheel is the larger of the two circular objects.

Front 27

mass

Back 27

The amount of matter that something is made of.

Front 28

inclined plane

Back 28

a simple machine that is a straight, slanted surface.
a ramp, water slide

Front 29

inertia

Back 29

the tendency of all objects to resist any change in motion.
