Solution
According to Newton’s 2 nd law of motion,
F = ma
Where, F is the force applied, m is the mass of the body and a is the acceleration of the body.
So,
In absence of a force,
F = 0
=> ma = 0
=> a = 0
Since, m cannot be zero for a body.
Zero acceleration means, body at rest will remain at rest and a body in uniform motion will continue its uniform motion. Which is Newton’s 1 st law of motion.
