Answer: Newton's firs law in terms of acceleratation: a body will exhibit zero acceleration unless a net force acts on it.
Explanation:
1) Newton's first law is also known as inertia law.
2) Newton's first law is usually stated in terms of motion: a body at rest or in uniform straight motion will keep its condition of rest or of constant speed in straight line unless a force acts on it.
3) Being at rest or at constant velocity is the same that having zero acceleration.
4) That permits to restate Newton's firs law in terms of acceleratation: a body will exhibit zero acceleration unless a net force acts on it.
