Question

Newton’s second law says that when an __________________ force is applied to a ________________, it causes it to __

Answer 1

Explanation:

Newton's second law says that when a constant force acts on a massive body, it causes it to accelerate that is to change its velocity at a constant rate. In the simplest case, a force applied to an object at rest causes it to accelerate in the direction of the force.

Answer 2

Newton’s second law says that when an unbalanced force is applied to a body, it causes it to accelerate.

Explanation:

According to the Second law of motion:

Force is defined as rate of change of momentum with respect to time.

• $F$ ∝ $\frac{dp}{dt}$ , where $t$ is time and $p$ is the momentum of the body and it is given as mass times velocity.
• So,
• $F=\frac{d(mv)}{dt} =m\frac{dv}{dt} =ma$, where $a$ is the acceleration of the body.
• Unbalanced force is the net force acting on the body which is non zero.
• When all the forces acting on the body is added considering signs according to the direction, a non zero value to this resultant force is considered as case of unbalanced force.
• Unbalanced force takes a body out of equilibrium and causes it to accelerate.
