Presentation transcript:

Any moving object that has mass, has kinetic energy. = kinetic energy (J) m = mass (kg) v = speed (m/s) Kinetic energy is energy due to motion. The kinetic energy of an object varies directly as its mass. So, for example, if you double the mass of an object, its kinetic energy will double. The kinetic energy of an object varies directly as the square of its speed. This is a “direct squared” relationship! So, for example if you double the speed of an object, its kinetic energy will increase by a factor of four.
