Ch.2 Laws of Motion
momentum
measure of hoe hard it is to stop a moving object
inertia in motion
p=m*a
elastic vs inelastic collisions
elastic collision - two objects are bounce off
inelastic collision - two objects are stick together
mass
measure of inertia
a net force
the combination of all the forces acting on an object
inertia
the tendency of an object to resist a change in its motion
units
force = N / mass = kg / acceleration = m/s squared
three ways to accelerate
speeding up, slowing down, and changing directions
Newton's third law
every action has an equal and opposite reaction
action-reaction force pair
they never cancel
because each force acts on a different object
Law of conversation of momentum
no matter what type of collision it is, the total momentum will be the same before and after
reference direction
balanced force vs unbalanced force
Newton's second law (F=m*a)
force acting on a moving object in the same direction vs different direction
