 Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Force and acceleration have
 A a direct relationship B an inverse relationship C Either A or B D None of the above
Explanation:

Detailed explanation-1: -Newton’s second law shows that there is a direct relationship between force and acceleration. The greater the force that is applied to an object of a given mass, the more the object will accelerate. For example, doubling the force on the object doubles its acceleration.

Detailed explanation-2: -So there must be some relation between force and acceleration and this is given by Newton’s second law. According to Newton’s second law: F = ma. From the above relation, we can say that acceleration not only depends on the force applied but also on the mass of the body on which it is applied.

Detailed explanation-3: -The acceleration of an object is directly proportional to the net force and indirectly proportional to the object’s mass (a = f/m).

Detailed explanation-4: -The acceleration is directly proportional to the net force; the net force equals mass times acceleration; the acceleration in the same direction as the net force; an acceleration is produced by a net force.
