A unit of measure that equals the force required to accelerate 1 kg of mass at 1 meter per second
What is a newton?
100
The rate at which velocity changes
What is Acceleration?
100
The fluid friction on experienced by objects falling through the air
What is Air Resistance?
100
The overall force on an object when all the individual forces acting on it are added together
What is net force?
100
The force that two surfaces exert on each other when they rub against each other
What is Friction?
200
If one object exerts a force on another object, then the second object exerts a force of equal strength in the opposite direction on the first object
What is Newton's 3rd law of motion?
200
The tendency of an object to resist any change in its motion
What is Inertia?
200
A force that causes an object to move in a circle
What is centripetal force?
200
The distance an object travels per unit of time
What is speed?
200
Occurs when an object rolls over a surface
What is Rolling Friction?
300
An object at rest will remain at rest, and an object moving at a constant velocity will continue moving at a constant velocity, unless it is acted upon by an unbalanced force
What is Newton's first law of motion?
300
The force of gravity on an object at the surface of the planet
What is weight?
300
The amount of matter in an object
What is mass?
300
Speed in a given direction
What is velocity?
300
Friction that occurs when one solid surface slides over another
What is Sliding Friction?
400
Acceleration depends on the object's mass and on the net force acting on the object. Net force
------------
Mass
What is Newton's second law of motion?
400
The greatest velocity a falling object can achieve
What is Terminal velocity?
400
Equal forces acting on an object in opposite directions
What is balanced forces?
400
Forces that produce a nonzero net force, which changes an object's motion
What is unbalanced forces?
400
Friction that occurs as an object moves through a fluid
What is Fluid Friction?
500
Scientists all over the world use the same system of measurement so they can communicate clearly.
