Front 1

Newton's 3 laws of motion

Back 1

1st law: A body at rest remains at rest and a body in motion in motion until an outside force acts on it (inertia).

2nd law: A force causes an object to accelerate.

equation---> f=mass x acceleration

3rd law: for every there is an equal & opposite reaction.

Front 2

kinetic energy

Back 2

energy in motion.

kinetic energy=1/2 mass(velosity)2

Front 3

potential energy

Back 3

stored energy; the ability of a system to do workdue to its position internal structure.

gravitation potential energy=mass x gravity x height

Front 4

The Law of conservation of energy

Back 4

energy cannot be created or destroyed only converted to another type of energy.

Front 5

solar energy

Back 5

converts energy to chemical energy.

Front 6

FRICTION

Back 6

the rubbing of one object or surface against another.

Front 7

1.)Conduction

2.)Conduction

3.)Radiation

Back 7

transfer of heat through an object from a source

tranfer of heat by liquid or gas.

heat transfered by electromagnetic waves.

Front 8

Gravity

Back 8

gravity will accelerate all objects at the same rate regardless of their mass. this is why a marble and a bowling ball when dropped from a building will hit the ground at the same time.

Front 9

Physical properties

Back 9

all properties that can be determined without changing the identity of the substance, such a color,density,phase (liquid,solid,or gas),odor,boiling & freezing points and solubility.

Front 10

chemical properties

Back 10

a characteristic that a substance display when it changes into a new substance.

Front 11

physical change

Back 11

a change that does not create a new substance.

Front 12

chemical change

Back 12

any change that produces a new substance.

Front 13

freezing

Back 13

when a liquid becomes a solid.molecules become packed tighter together moving less.

Front 14

melting

Back 14

occurs when a solid changes to a liquid allowing molecules to move more freely.

Front 15

evaporating

Back 15

when a liquid becomes a gas.the molecules are now move ing very rapidly.

Front 16

condensation

sublimation

precipitation

Back 16

when a gas becomes a liquid.

when ice goes from a solid directly into a gas.

during a water cycle,when clouds can no longer hold all the water from condensation,the cloud will release the water in the form of rainor snow.

Front 17

density

Back 17

allows objects to float or sink

d=m/v

Front 18

atom

Back 18

smallest particals of a of element that has all the properties of that element.

Front 19

element

Back 19

a pure substance that cannot be broken into simpler substances.

Front 20

electrons

neutrons

protons

Back 20

negitive charge

neutral charge

positive charge

Front 21

wave length

amplitude

frequency

Back 21

the length of one complete wavelength cycle.

a measure of the energy a wave carries.

the # of waves that pass a point in a given amount of time.

Front 22

telescope

spaceship

satillites

probes

Back 22

you can see things closer in outer space.

allows astronauts to travel into space.

are used to transmitt signals from space.

are sent by scientist to collect data from far away planets.

Front 23

solar eclipse

lunar eclipse

Back 23

occurs when the moon is in front of the sun.

occurs when the earth blocks our view of of the moon.

Front 24

endothermic

exothermic

Back 24

a reaction that absorbs heat from around them.

a reaction the give off heat.

Front 25

3 different types of galaxies

Back 25

1.) spiral

2.) eliptical

3.) irregular

Front 26

fossils

Back 26

a piece or a trace of an organism that was once alive they are mainly found in sedimentary rocks.

Front 27

Artic tundra

Rainforest

Desert

Back 27

temperatures are extremely cold year round.

is a location a because lots of precipitation.

is location b because it's copletly dry nothing but sand.

Front 28

1 being softest

10 be hardest

Back 28

1.) talc

2.) gypsum

3.) calcite
