According to newton's second law of motion, force is equal to mass times acceleration. true or false.

According to the Newton’s Second law of motion, the force is equal to mass times acceleration. It is a true statement.

Further Explanation:

According to the Newton’s second law of motion, the force exerted on a body is defined as the rate of change of momentum of the body.

The Newton’s second law can be expressed mathematically as:

Here,  is the momentum of body and  is the force applied on the body.

We know that, the momentum of a body can be expressed as the product of mass and velocity as:

Here,  is the mass of the body and  is the velocity attained by the body.

Substitute the value of  in above expression.

The rate of change of velocity is termed as the acceleration.

Substitute  for  in the above expression of force.

Thus, according to the Newton’s Second law of motion, the force is equal to mass times acceleration. It is a true statement.
