Ignoring energy lost to friction, a rollercoaster car that has reached the halfway point while descending a hill has _____________. A. half as much kinetic energy as potential energy B. the same amount of kinetic energy and potential energy C. twice as much kinetic energy as potential energy D. four times as much kinetic energy as potential energy
Weegy: B. The same amount of kinetic energy and potential energy. As long as the track downhill has a uniform slope. User: A 25 kg girl steps off a diving platform that is 2 m high. Neglecting the effects of friction, what is the girl's speed just before she hits the water? Weegy: 6.264 meters/sec User: Which energy transformation propels a marathon runner across the finish line? A. chemical energy to kinetic energy B. heat energy to mechanical energy C. mechanical energy toelectrical energy D. kinetic energy togravitational potential energy Weegy: A. chemical energy to kinetic energy. We burn food and nutrients in a chemical process to create the energy we use. User: If an object is brought to the Moon (where gravity is about one-sixth of Earth's gravity), how will the object's kinetic energy change when it is dropped from the same height on the Moon as it was dropped from on Earth? A. It will be about 2 1/2 times less. B. It will be about 6 times less. C. It will be greater. D. It will be the same. (More)

For many years inventors tried to develop a perpetual motion machine, one that would continue moving forever once it was set in motion. They were never successful because
Weegy: A machine that could run forever. A perpetual-motion machine would have to produce at least as much energy as was needed for its operation. [ According to the second law of thermodynamics, such a machine is impossible, and to date none has ever been successfully demonstrated. Read more: ] (More)

When you are running, there is friction between your feet and the ground and air resistance between your body and the air. Where does the extra energy that keeps you moving come from? A. kinetic energy B. chemical potential energy C. potential energy of springs D. gravitational potential energy
Weegy: Wheels, ball bearings, the Egyptians building the pyramids using tree trunks to move the stones. gravitational potential energy An example of rolling friction would be like a skateboard rolling on a sidewalk. [ [ An example of rolling friction would be rolling Timothy Kely student at ACEC down a hill. ] D. gravitational potential energy ] (More)
