All moving objects that have mass have kinetic energy
As mass increases, the KE increases
As speed increases, the KE increases
KE changes more with speed than with mass
KE = mass x speed 2
Kinetic Energy Kinetic energy (joules) KE = ½ m v 2 m - mass of the object in kg v - speed of the object in m/s KE - the kinetic energy in J
Kinetic Energy depends on two things: mass and speed The amount of kinetic energy the cart has is equal to the amount of work you do to get the cart moving A cart at rest has NO Kinetic energy Applying a force can give the cart speed, and therefore kinetic energy. Applying a greater force increases the speed and therefore the kinetic energy Increasing the mass also increases kinetic energy because it takes even more force to push.
Work-Energy Theorem the net work done on an object is equal to its change in kinetic energy
