Definitions:
How fast an object is moving; distance traveled divided by time.
The measure of a gravitational force on an object.
A push or pull, measured in Newtons.
A change in position over time when compared to a reference point.
D/T or Distance divided by Time.
A substance applied to a surface to reduce friction.
A type of friction involving a liquid or a gas.
This occurs when an object speeds up, slows down, or changes
direction. It is the change in velocity over time.
Describes the relationship between force, mass, and distance.
(Vf – Vi)/T or (final velocity – initial velocity)/time
The type of friction that holds a non-moving object in place.
The unit of measure of mass.
A force that opposes (slows down) motion between two surfaces
that are touching.
The speed and direction of an object.
When these forces act on an object, there is a change in motion.
The amount of matter in an object.
A force between two objects due to their masses and the distance
between them.
When you observe motion, you compare a moving object to
something that appears to stay in place. The object that appears to
stay in place is called a ______________.
The type of friction that involves wheels or tires.
When these forces act on an object, there is no change in motion.
Total distance traveled divided by total time.
The unit of measure for force.
This is found by combining all of the forces acting on an object.
The type of friction between two objects that rub or slide against
each other.
One example of a unit of measure for acceleration.
This object is…
Speeding up
(Circle One):
Slowing Down
This object is…

The dashed line
The solid line
Look at the following diagrams and find the net force on each object. Write the size and
direction (up, down, left, or right) of the net force on each object.
