$\Huge\purple{\mathfrak{\underline{\underline{answer}}}}$

$\textbf{Newton's first law}$

✅Newton's first law states that a body at rest will remain at rest, and a body in motion will remain in motion with a constant velocity, unless acted upon by a force.

✅This law is also called the law of inertia .

$\textbf{Newton's second law}$

✅Newton's second law states that a force acting on a body is equal to the acceleration of that body times its mass.

✅Expressed mathematically, F = ma, where F is the force in Newtons, m is the mass of the body in kilograms, and a is the acceleration in meters per second per second.

$\textbf{Newton's third law}$

✅ Newton's third law states that for every action there is an equal and opposite reaction.

✅Thus, if one body exerts a force F on a second body, the first body also undergoes a force of the same strength but in the opposite direction.

✅This law lies behind the design of rocket propulsion, in which matter forced out of a burner at high speeds creates an equal force driving the rocket forward.
