Define the terms force, speed, velocity, displacement,
acceleration, momentum, and impulse.
Force: (vector) the mechanical
interactions between two objects or bodies. Measured in Newtons (N). F=ma
Speed: (scalar) the distance an object
travels per unit of time. speed=distance/t
Velocity: (vector) the speed of an
object in a certain direction. The displacement per unit time. V=d/t
Displacement: (vector) how far and in
what direction is the end position from the starting position.
Acceleration: (vector) the change in an
objects velocity over a certain amount of time. a=Δv/Δt
Momentum: (vector) the property an
object has due to its movement. Momentum is the mass of an object times its
velocity. p=mv
Impulse: (vector) force multiplies by the time it acts. J=Ft=mΔv
