Which one is NOT a part of Newton's 1st Law?
An object in motion remain in motion.
An object at rest will remain at rest.
An unbalanced force will change an objects motion.
An object will never stop not matter what
Which is a common unbalanced force acting against applied forces?
Friction
inertia
acceleration
Momentum
Newton's first law is sometimes called:
Law of friction
Law of inertia
Law of conservation of Energy
Law of Conservation of Mass
Which of the following is the equation for Newton’s second law of motion?
Force = mass / acceleration
Work = force X distance
Power = work / time
force = mass X acceleration
According to Newton’s 1st law, a moving object that is not acted on by an unbalanced force will
eventually come to a stop.
accelerate.
remain in motion.
change its momentum.

How is speed defined?
acceleration/time
change in velocity/time
distance/time
displacement/time
Position vs Time Graph: A straight line with a slope (positive or negative) tells us that the object is
