Momentum
When ever something is moving it has BLANK
momentum
force is a BLANK or a BLANK
Push or pull
kicking a soccer ball is what type of force
push
what is a force
a push or a pull
what is the unit used to measure force
Newtons
momentum depends how BLANK something is
fast
hitting a golf ball with a club changes the BLANK of the ball
speed
opening a drawer toward you is what type of force
pull
what is Newton's first law also called
the law of inertia
what tool measures force
a spring scale
when ever things run into each other, momentum can Blank
Transfer
net force is the BLANK of all of the forces acting on an object
Combination
what can a force change about an object
its speed or direction
what is inertia
an objects resistance to changes in motion
what force slows objects down when surfaces rub together
friction
if you are not BLANK then you don't have any momentum
moving
if forces are in BLANK direction, the net force is the difference between the two forces
opposite
what happens when balanced forces act on a still object
it stays still
what happens to an object at rest if no unbalanced force acts on it
it stays at rest
what happens when an unbalanced force acts on a ocject
its motion changes
momentum is BLANK
movement
kicking a soccer ball as it flies toward you changes the
direction
a moving skateboard slows down because of friction. what changed its motion
an unbalanced force
why do you move forward when a car suddenly stops
you body's inertia keeps you moving forward
why does a soccer ball eventually stop rolling
friction slows it down
