Yes, the diver at the top of the diving board has potential energy due to their position above the ground. Once the diver jumps, this potential energy is converted to kinetic energy as they accelerate towards the water.
The change in energy of a person jumping off a rigid diving board is from potential energy at the top to kinetic energy at the bottom. At the top, the person has potential energy due to their height above the ground, which is converted to kinetic energy as they fall towards the ground.
No, a hammer held above a nail has potential energy due to its position relative to the nail. Potential energy is energy that an object has due to its position or state, whereas kinetic energy is energy of motion.
Its a bad example, but some potential energy is involved. You convert chemical energy from the fuel to kinetic energy and heat energy. The kinetic energy drives you into the water. There the car sinks because of the height difference and gravity. This is a form of potential energy. A better example would be a person driving up and down a mountain. When driving up a mountain you store kinetic energy into potential energy. On the way down you regain the potential energy you stored, which results in a higher kinetic energy when driving down.
No, a rock held above the ground does not have kinetic energy because it is not in motion. It instead has potential energy due to its position in the gravitational field ready to be converted to kinetic energy when released.
I think itz gravitational potential energy
Potential, changing to kinetic when you release it and it falls.
Basically, if it moves, it has kinetic energy. And if it is above ground level, it has gravitational potential energy.
Kinetic energy is the energy of motion. Heat is a form of kinetic energy (the movement of individual atoms or molecules) so the liquid phase contains more kinetic energy than the solid and the gas phase has more kinetic energy than the liquid phase. However, kinetic energy can also be imparted to a mass as a whole in which case if the total mass of the phases was constant the this imparted kinetic energy would be the same for all phases.
No, when the ball is held in a stationary position above the ground, it only has potential energy due to its position relative to the ground. Kinetic energy is associated with the motion of an object.
yes it is, but you can only have kinetic energy of the object is in motion and potential energy if the object is any height above zero
Blowing wind has kinetic energy. This can be transformed into electrical energy using a turbine to transform the wind into rotational kinetic energy and a generator or alternator to convert the rotational kinetic energy to electrical energy. Water above a dam has potential energy from gravity and also from the weight of the water around it. Once it is moving or flowing down through the pipes it then has kinetic energy.
