Question

a )Differentiate between potential and kinetic energy.

b) Derive equation K.E = 1/2mv2​

Answer 1

Answer:

"A"}= the energy possessed by an object by virtue of it being in motion. PE is the energy possessed by an object by virtue of its position. ... Kinetic Energy is already moving and is not at rest. Potential Energy is purely based on the position of the object and also the condition of the object.

"B"}=1/2 m (v^2) ; the squared only applies to the v. and v^2 = u^2 + 2as from the equations of motion. Rearrange for s, substitute f/m for a into the equation of motion, then substitute into work = f s.
