Question

You are riding on your bike and stop pedaling , coasting along the road. eventually, your bike slows down and stops. what happened to the energy of your motion when your bike stopped?

Answer 1

When still rolling your bike had kinetic energy, or energy in the form of motion. The forces resisting this motion--a mixture of many factors including air resistance, tire friction, friction in the hubs of the wheels, etc...--eventually decrease the kinetic energy of the bike to zero as it reaches a complete stop.
