-
p = m x v (mv)
p is momentum , m is mass , v is velocity

2.3 FREE FALL MOTION
Free Fall : Motion of an object is affected by gravitational force (no other forces - air resistance, friction)
Gravitational acceleration, g = 9.81ms-2 * In calculation, when object falls down, value of g is positive (+), when object is thrown up, the value of g is negative (-).

2.4 INERTIA
Newton's first Law of Motion : An object at rest will stay at rest, and an object in motion will stay in motion unless acted on by a net external force.
Inertia : The tendency of an object to remain at rest, or if moving to continue its motion in a straight line at uniform velocity
Inertia is affected by mass. The bigger the mass, the bigger the inertia
