What makes matter move?
Energy
100
What is it called when light bounces off of an object?
reflect
100
a force that pulls things toward Earth
gravity
100
What is the simple machine with a slanted surface?
a ramp
100
How does friction effect the way an object moves?
less friction = the object moves farther more friction = the object doesn't go as far
200
a kind of energy that can change the state of matter (for example, ice to water, water to gas)
heat
200
when light bends as it passes through something
refraction
200
a force that slows down moving things
friction
200
What is sound?
It is noise
200
What is friction?
Friction is when two objects rub together
300
a kind of energy that you hear
sound
300
a push or pull that makes something move or change direction
force
300
something that helps you move an object
simple machine
300
How does sound travel?
It travels in a wave.
400
a kind of energy that let's you see
light
400
how high or low a sound is
pitch
400
a simple machine made of a bar that rests on a fixed point.
lever
400
What are different ways objects move?
Push and Pull
400
What happens when you change the angle of a ramp?
If the angle is to steep or to low then the object will not go far. If the angle is between steep and low, it will go farther.
500
Something that gives off heat when it burns.
Fuel
500
when something moves back and forth
vibrate
500
the fixed point on which a lever rests
fulcrum
500
How can you change how far an object moves?
use more force, have less friction, make a ramp longer, etc.
