What force would be needed to produce an acceleration of \(2\, {\text{m}} { {\text{s}}^ { {\text{-2}}}}\)on an object of mass \(5\,{\text{kg}}\)?Ans: Given that,The acceleration to be produced in the object is \(a = 2\, {\text{m}} {{\text{s}}^{ {\text{-2}}}}\)The mass of the object is \(m = 5\, {\text{kg}}\)The required force is \(F = m \times a = 5 \times 2 = 10 {\text{N}}\)Thus, \(10 {\text{N}}\)of force is required to produce an acceleration of \(2\, {\text{m}} { {\text{s}}^ { {\text{-2}}}}\)on an object of mass \(5\,{\text{kg}}\). In other words, Fnet=ma . In the third law, when two objects interact, they apply forces to each other of equal magnitude and opposite direction. We will see that the lighter body will pick up more speed than the heavier body, but in the end, if we check the momentum of both bodies, we will see that both have the same momentum. Newtons second law is a quantitative description of the changes that a force can produce on the motion of a body.

Weight can be represented by a vector because it has a direction. Equal forces were acting on both the bodies, which means the rate of change of momentum of each body was the same. In the third law, when two objects interact, they apply forces to each other of equal magnitude and opposite direction. This can be expressed in the equation F = ma, where F is the force applied, m is the mass of the object, and a is its acceleration. Thus, an object of constant mass accelerates in proportion to the force applied. As the acceleration or mass of the car increases, the force with which a car crash takes place will also increase.
