created or destroyed
the motion of an object is an objects direction and ___________.
SPEED
when objects collide the energy is ___________ from one object to another
transferred
speed is how ____________ an object is moving
FAST
what is an independent variable

Kinetic
friction is the force that ___________ of an object
opposes the motion
a ball rolling down a hill has what type of energy (kinetic or potential)
kinetic
what is a dependent variable
the results of what changed in an experiment
(how how my plants grew when i watered them with orange juice vs water)
energy can _________ from one to another
TRANSFER
(ex: a stove starts as electrical then transfers into thermal)
if force is applied to an object the object will move in what direction?
A. the opposite direction of the force
B. The same direction of the force
B. The same direction as the force
(ex: when you push a shopping cart it moves which every direction you pushed it)
any action (push or pull) that causes an object to move, stop, change speed, or direction
