Newton's Laws, Part 2

TermDefinition
Action-Reaction Newton's 3rd Law is sometimes called
force This is what is equal, but opposite in Newton's 3rd Law
pairs Forces always occur in these
equal Colliding forces are always this in size
momentum Mass times velocity calculates this
mass x velocity Momentum is calculated using this formula
kg-m/s The SI derived unit for momentum is this
transferred What happens to the momentum from one object to another in a collision
conserved In an isolated system, the total amount of momentum is
gases Rockets propel themselves by pushing off of their
rocket In rocket propulsion, the force pair is rocket on gases, gases on
mass The gases accelerate out of the rocket so fast because of the rocket's great amount of
1st Newton's laws of motion about inertia
2nd Newton's law showing the relationship of acceleration to force and mass
3rd Newton's law of action-reaction forces
velocity Momentum is mass times this
p Momentum is represented by the letter,
acceleration Force divided by mass is this
simultaneously Force pairs occur at this time
conservation The total momentum before a collision is equal to the total momentum after a collision is the law of __ of momentum.
