p=mvp = mvp=mv (mass × velocity)
Vector (has magnitude and direction)
kg m s⁻¹ (kilogram metre per second)
Body at rest/constant velocity unless net external force acts
Tendency of objects to resist changes in motion
F=maF = maF=ma (force = mass × acceleration)
F=ΔpΔtF = \frac{\Delta p}{\Delta t}F=ΔtΔp (rate of change of momentum)
Constant speed when air resistance equals weight
Weight = air resistance, net force = 0, acceleration = 0
For every action force, equal and opposite reaction force
Equal magnitude, opposite direction, act on different objects
80,000 kg m s⁻¹ east
