Answers:here are examples of potential: - a roller coaster on the top of a hill track. - a rocket ready for takeoff. - a snowball on top of a snowy mountain. here are examples of kinetic: - a group of people pushing a car. - a team of sled dogs pulling a sled. - a bunch of bulldozers pushing a large boulder. - kids on a see-saw. - people moving furniture.
Answers:Gravity is the force acting on changing potential energy to kinetic in your setup. kinetic energy = the negative change in potential, and since gravity is the force applied to cause the change in potential, therefore it is also the force that changes kinetic energy. Friction changes energy into heat, so it does not apply to the question your teacher asked.
Answers:Answer: 3, 5 & 7. Kinetic energy is energy of motion. The kinetic energy of an object is the energy it possesses because of its motion. The kinetic energy* of a point mass m is given by KE = 1/2mv2 Kinetic energy is an expression of the fact that a moving object can do work on anything it hits; it quantifies the amount of work the object could do as a result of its motion. The total mechanical energy of an object is the sum of its kinetic energy and potential energy. Dr. H
Answers:Potential energy is stored energy, kinetic is released energy. 1) Potential 2) Kinetic 3) Potential 4) Kinetic Hope this helps.
