What are factors that affect the amount of friction between surfaces.
300
The type of forces that cause an object to start moving.
What are unbalanced forces.
300
The force that you need to produce a change in motion.
What is unbalanced force.

What is meters per second.
400
Two forces act on an object. One has a magnitude of 15 N north and the other has a magnitude of 28 N south. What is the net force experienced on the object.
What is 13 N south?
400
As the distance between two objects decreases, what happens to the gravitational force between those two objects?

500
The rate at which velocity changes over time.
What is acceleration.
500
This is the frictional force that keeps an object stationary.
What is static friction?

A student is moving to the back of the bus as the bus travels forward down the street. The bus is traveling at 12 m/s to the east, and the student is traveling at 4 m/s to the west. To an observer standing on the street, how fast does the boy appear as though he is moving?
What is 8 m/s east?
500
This is the type of acceleration that produces circular motion.
What is a centripetal acceleration?
500
Explain why your weight would change if you leave the planet Earth.
Because the gravitational force acting on your body would change, and weight is affected by gravity.
