golf ball
soccer ball
football
baseball
Inertia explains why
friction can be overcome for all objects
people in a car move forward in their seats when the car stops quickly
the ground pushes against your feet when you run
gravitational forces are stronger on Earth than on the Moon

volume
speed
mass
inertia
If two arm wrestlers exert a force on each other's hands, and the hands don't move, the forces must be
strong
resistant
balanced
unbalanced
An object at rest will remain at rest unless...
it continues in a straight line
a nearby magnet attracts it
an outside force acts on it
it is placed on a sloped surface
A soccer ball that has been kicked across the field will eventually slow down and stop on its own. Which force is responsible for this and why?
Gravity, it pulls everything to the earth.
Friction, the ground rubs against the ball, slowing it down.
Weight, the ball is not weightless so it must stop eventually.
Will the top wagon or the bottom wagon require the most force to pull it?
Top
Bottom
What is the formula to calculate speed?
Time x Distance = Speed
Distance + Time=speed
Distance divided by time = speed
Time divided by distance = speed

Applied Force
Gravity
Magic
Another word for weight is
height
length
mass
force
