Changes in Motion going a different direction, starting from a stopped position, slowing down, etc.
Gravity would cause a ball to fall
Meter sticks measure distance
stopwatch measures time
speed is a measure of motion
motion is described by an object's direction and speed
Object's motion can be described as forward, backward, left, right, down, etc.
increased As mass is __________________________, the amount of force needed increases.
greater The _______________________ the mass, the more force needed to move the object
action For every _________________, there is an equal and opposite reaction.
Law of Inertia An object in motion will remain in motion or an object at rest will remain at rest unless acted on by another object.
less Smooth, slippery items have __________ friction.
slowing Friction changes the movement of an object by ________________ it down.
kinetic All moving objects have __________________ energy.
potential Energy that may happen is ___________________ energy.
electrical A lamp and a computer are ___________________ energy.
heat transfer A puddle being heated by the sun is an example of ________ __________________ through radiation.
chemical A car burning fuel to drive down the street is an example of ______________ energy.

metal Materials made of _______ are common electrical conductors.
Relative Location The position of an object can be described by locating it relative to another object or to the background.
force A _________ is any push or pull that causes an object to move, stop, or change speed or direction.
friction ________________ is the resistance to motion created by two objects moving against each other. It creates heat.
stop Friction tries to ________ or SLOW an object.
smoother The _______________ or Flat the LESS Friction.
steeper The_________________ and Rough the MORE Friction.
