Question

If the kinetic energy of a particle is directly proportional to time ,then how does force depend on time​

Answer 1

KE = 1/2 mv^2

=1/2 m(d/t)^2

From v = d/t

Therefore KE is proportional to time

Since

Force = mass × acceleration

F=m × a

= m× (v/t)

= m×(d/t^2)

There fore Force is directly proportional to displacement
