Question

Explain Newton's laws of motion.

Answer 1

Newton's Laws of Motion:

• Newton's first law of motion states that a body continues to be in a state of rest or of uniform motion (with a constant velocity) until and unless a net external force acts on it.
• Newton's second law of motion states that the net external force applied to a body is equal to the rate of change of its momentum.

${\overrightarrow{F}}_{ext}=\frac{\overrightarrow{dP}}{dt}$

• Newton's third law of motion states that every action has an equal and opposite reaction. These action-reaction forces act on two different bodies.
