Starting from rest, a ball of mass 2 kg experiences a constant force of 8 n. what is the final kinetic energy (in j) of the ball after it has traveled a distance of 8 m?

Abody of weight 60 kg is standing in a lift the lift going upward with a uniform velocity of 4.9 metre per second slows down and stops in two seconds then apparent weight of the body during the slow down process is

Starting with only the balmer series light (visible light), how could we ensure that the solar panels generate a current that mark can use for his power station? a)by gradually increasing the brightness (amount) of light that we shine on it. b)by gradually increasing the frequency of the light we shine on it. c)by gradually increasing the wavelength of the light that we shine on it.

Based on this activity, is kinetic energy always transformed into potential energy?
