This is a measure of how fast something moves through a distance in a given amount of time.
What is speed?
speed - ?
time - 6 hours
Distance - 30 miles
5 miles per hour
distance / speed =
Time
speed x time = ?
distance
What is the formula to calculate distance?
speed x time
A force that slows down objects when they rub against each other
What is friction?
What formula would you use to find time?
distance / speed
Name a surface with low friction

9 seconds
What happens if there is no force acting upon an object?
It will continue to move at the same speed in the same direction.
An object's resistance to any change in motion
What is inertia?
50 N right and 60 N left will result in.
10 N left
A change in a moving object's speed or direction is..
What is Acceleration?
Interpret the graph below?
This is the force that pulls things to the center of the earth.
What is gravity?
What is the formula to calculate speed?
What is distance divided by time?
