Explain the equations of motion, all three.
(Class 9, Force and Laws of Motion)
Answers
Answer:
Newton’s First Law of Motion also known as Law of Inertia states that every object persists to stay in uniform motion in a straight line or in the state of rest unless an external force acts upon it.
Newton’s Second Law of Motion states that force is equal to the change in momentum per change in time. For a constant mass, force equals mass times acceleration, i.e. F = m*a. Learn about the Acceleration in detail here.
Newton’s Third Law of Motion states that for every action there is an equal and opposite reaction.

Answer:
▪︎EQUATION OF MOTION -
There are three equations of motion that can be used to derive components such as displacement(s), velocity (initial and final), time(t) and acceleration(a). The following are the three equation of motion:
♡. First Equation of Motion : v = u+at
♡. Second Equation of Motion : s = ut+1/2at²
♡. Third Equation of Motion : v² = u²+2as
