which produces the greater changes in kinetic energy: exerting a 10n force for a distance of 5 m or exerting a 20 n force over a distance of 2 m? (assume that all of the work goes into ke)



Answer :

A 10N force for a distance of 5 m will produce the greater change in kinetic energy of the body.

According to the work energy theorem, the change in kinetic energy of the body is equal to the work done by the forces on the body.

So, we can write,

W = ΔK

ΔK in kinetic energy change,

W is the work done.

Now, the force is 10N exerted over a distance of 5m. so,

10 x 5 = ΔK

ΔK = 50J.

Now, the exerted force is 20N over a distance of 2m, so,

20 x 2 = ΔK

ΔK = 40J.

Hence, the 20N force is producing more change in kinetic energy of the body.
