Kinetic Energy

discussion summary practice problems what is kinetic energy? Kinetic energy is a simple concept with a simple equation that is simple to derive. Let’s do it twice. Derivation using algebra alone (and assuming acceleration is constant). Start from the work-energy theorem, then add in Newton’s second law of motion. ΔK = W = FΔs = maΔs Take the the appropriate equation from kinematics and rearrange it ...
