100
The force that two surfaces exert on each other when they rub against each other
What is friction?
100
any force that causes an object to move in a circular path.
What is circular motion/centripetal force?
100
is the force that pulls objects toward each other.
What is gravity?
100
when the only force acting on an object.
What is free fall
100
objects falling through air experience a type of fluid friction
What is air resistance?
200
the friction that acts on objects that are not moving.
What is static friction?
200
satellites in orbit around earth continued fall toward earth, but because earth is curved they travel around it.
What is satellite motion?
200
a measure of the amount of matter in an object
What is mass?
200
the greatest falling object
What is terminal velocity?
300
occurs when two solid surfaces slide over each other
What is sliding friction?
300
the force of gravity on a person or object at the surface of a planet.
What is weight?
300
an object that is thrown
What is projectile?
400
when an object rolls across a surface.
What is rolling friction?
500
occurs when a solid object moves through a fluid.
What is fluid friction?
