What is a force?
a push or a pull on an object
100
\What happens in static friction?
Objects aren't moving
100
What does Newton's First Law of Motion states?
states that motion does not change as long as the net force acting on the object is zero
100
What does Newton's Second Law of Motion states?
the acceleration of an object is equal to the net force acting on it divided by the object's mass
100
What does Netwon's Third Law of Motion states?
whenever one object exerts a force on a second object, the second object exerts an equal and opposite force on the first object
200
What does forces cause changes in?
Velocity, acceleration or direction
200
What happens in rolling friction?
movement is forward, not side to side
200
What is it also called ?
the law of inertia
200
What is the formula?
F=MA
200
What is momentum?
the quantity of motion of a moving body, measured as a product of its mass and velocity
300
What is net force?
the overall force acting on an object after all the forces are combined
300
What happens in sliding friction?
Objects are sliding past each other
300
What is inertia?
the tendency of an object to resist a change in its motion
300
It is always in the same direction as the ___?
net force
300
Action-Reaction pairs can cause ____?
Motion
400
What happens in balanced forces?
The net force is zero, no acceleration
400
What happens in fluid friction?
all objects are moving through a fluid: liquids or gases- anything that flows
400
What is the formula for momentum?
P=MV
500
What happens in unbalanced forces?
objects accelerates
500
