What is a Newton?
A collision where a car is crushed on impact.
What is inelastic collision?
A quantity that is described as having only magnitude.
What is scalar quantity?
For every action there is an ___ and ___ reaction.
What is equal and opposite?
The SI unit for mass.
What is a kilogram?
A change in momentum.
What is impulse?
A quantity that is described as having both magnitude and direction.
What is vector quantity?
Force = mass x ___
What is acceleration?
Distance/time
What is speed or velocity?
Which has the more momentum: a 1 ton car moving at 100km/h or or a 2 ton truck moving at 50km/h?
What is they have the same momentum?
A push or pull exerted on an object.
What is force?
Newton's law that is known as the law of inertia.
What is Newton's 3rd law of motion?
P = mv
What is momentum equation?
If a cue ball hits a 8 ball head on, the cue ball comes to a complete stop. The cue balls momentum will transfer to the 8 ball with some momentum lost. True or False?
What is false? The momentum will be conserved and the 8-ball will move in the same direction with the same momentum.
What is elastic collision?
Newton's law that is known as the action-reaction law.
What is Newton's third law of motion?
The constant g represents ___.
What is the acceleration of gravity?
If you were to be hit by a football lineman, would it be better to be extend the time of contact or shorten the time of contact? Why?
What is extend the time of contact? Less force occurs if momentum is decreased over a longer time period.
The force upon an object due to gravity.
What is weight?
