The force that one surface exerts on another when the two rub against each other is called:
friction.
inertia.
acceleration
gravity
The force of gravity on a person or object on the surface of a planet is called
mass.
weight.
terminal velocity
free fall.
The law of universal gravitation states that any two objects in the uni-verse that have mass, without exception,
attract each other.
repel each other.
combine to provide a balanced force.
create friction
Define the term inertia.
the amount of matter in an object
the amount of space an object takes up
the tendency of an object to resist a change in motion, determined by mass
The force that one surface exerts on another when the two rub against each other
How is it possible to have a constant speed but a changing velocity?
By slowing down
Changing Mass
Changing Direction
You can't speed and velocity are both the same
What does the slope on a velocity vs. time graph tell you?
Speed
Acceleration
Velocity
Direction
