Energy Flashcards
describe the changes in energy that occur when a person travels down a helter skelter
gravitational potential energy is transformed into kinetic energy. Some kinetic energy is transformed into heat energy due to friction
why does a cyclist not reach as high a speed as calculated when they go down a hill
work is done against direction/air resistance as heat energy due to friction is released into the surroundings
what is the energy change that takes place when a car brakes to a stop
kinetic energy is transformed into heat energy
2 factors affecting the size of kinetic energy an object has
velocity
mass
what type of energy does a snowboarder on a ski lift gain
gravitational potential energy
what happens to heat energy generated when an object brakes to a halt
it warms up the surroundings
