Answer:
The second law is given by
F = m a
Step-by-step explanation:
Newton's second law is the real law.
It shows that the force acting on the object is directly proportional to the rate of change of momentum of the body.
F = m (v - u) / t
F = m a
where, m is the mass of the body, a is the acceleration, v is the final velocity and u is the initial velocity.
If the mass is halved and to keep the force same the acceleration is doubled.
