Q
Newton’s first law
A
An object continues in its state of rest or uniform motion in a straight line unless acted upon by an external agent (Force)
2
Q
Newton’s second law
A
Resultant force is directly proportional to the rate of change of momentum on a body and is in the same direction
3
Q
Newton’s third law
A
For every action, there is an equal and opposite reaction
4
Q
Principle of conservation of momentum
A
It states that in an isolated system, the net momentum of bodies before the interaction always equals the net momentum after interaction
