What are Newton's laws of motion ?
Answers
there are three laws of Newton
first law of Newton :
an object continuous to remain rest or at the state of uniform motion along a straight line unless an external unbalanced force acts on it
Newton's second law:
the rate of change of momentum is proportional to the applied force and the change of momentum occurs in the direction of force
Newton's third law of motion:
every action force has equal and opposite reaction force which acts simultaneously
Newton stated three laws of motion:
Newton's first law: Inertia
Inertia means it is the inability of body to change its state of rest or state of motion by itself until an external force is applied.
When a body is in the state it remains in the state of rest until an external force is applied.
Similarly in the case of state of motion.
Newton's second law:
The external force acting on a body is directly proportional to the rate of change in momentum.
From newton's second law, we get
F = ma.
Newton's third law:
According to Newton's third law, for every action there is an equal and opposite reaction.
