Question

Q9. Write newton's first law of motion.
Q10. Write the mathematical derivation of Newton's second law of motion .​

Answer 1

Explanation:

Newton's first law says that if the net force on an object is zero ( Σ F = 0 \Sigma F=0 ΣF=0\Sigma, F, equals, 0), then that object will have zero acceleration. ... In other words, constant zero velocity—at rest—or constant non-zero velocity—moving with a constant velocity.

Answer 2

Answer:

initial velocity =u

final velocity=v

time taken=t

mass=m

rate of change of momentum=initial velocity-final velocity/time

=m∆v-m∆u/t

=m(v-u) /t

acceleration=v-u/t

rate of change of momentum=mass*acceleration
