chemical energy from food the rider has eaten gets turne into kinetic energy as the bike is moving. Then into potential energy as the bike heads uphill. As the bike heads down potential energy turns into kinetic energy.
Chemical energy from your food gets turned into kinetic energy and heat as your muscles work to power the bike forward. If you ride uphill chemical energy is also turned into potential energy.
the food gives you energy to move your muscles to moving the bike.
A human riding a bicycle will be using up chemical energy from the food he's eaten, and turning that into kinetic energy. If the ride takes him up a hill he will also gain potential energy.
Matter is unchanged.
Total Energy is also unchanged, but its form is changed (from chemical to mechanical to kinetic and finally into heat).
The rider uses chemical energy from the food he has eaten
the chemical energy stored in our muscles is used up when riding a bike.

When the rider is at the top of the hill, her potential energy is the greatest, and her kinetic energy is the least.
That is potential energy.
Energy can neither be created nor destroyed. It is converted to other forms of energy. There is potential energy and kinetic energy. Sitting on your bicycle on top of the hill you have no kinetic energy, only potential energy. When you ride down the hill, the potential energy is used up (you go down the hill) and it converts to kinetic energy (speed). "What happens when you stop at the bottom of the hill - wasn't the potential and kinetic energy destroyed?" No. All the potential energy was converted to kinetic energy. The kinetic energy was converted to heat through the wind resistance. So, if you had an extremely accurate thermometer, you would see the air and bicycle temperature rise as you went down the hill.

A.A child riding a bicycle down the streeta car in motion has kinetic energy because, Kinetic energy is energy due to motion.
No. On top of the hill the bike would have potential energy. If released, by letting the bike roll downhill, it'd turn into kinetic energy as the bike picks up speed.
Yes, because potential energy is energy stored but kinetic is energy in motion.
A rock on top of a hill has potential energy, not kinetic energy. If it starts rolling down the hill then the potential energy transforms to kinetic energy.
