The mass affects the kinetic energy because the more the mass the more energy is given to the object and the speed<span> affects by making it go faster and longer, so whenever speed goes up so does energy.</span>
Kinetic energy is when an object or person is moving.
Ex: A car going down the street.
Mass effects kinetic energy because mass is weight and weight will make an object go slower which lowers the kinetic energy and rises the potential energy (that's when a object is at rest or not moving)
