That's the correct procedure. The two calculations might or might not produce the same number.Coco12 said:U would minus the 43.6 from the 155 to get the height for the formula whereas u would use the velocity to get the kinetic ?

Kinetic energy is the energy an object possesses due to its motion. It is calculated by the mass of the object multiplied by its velocity squared, and is measured in joules (J).
Potential energy is the energy an object has due to its position or state. It can be further divided into gravitational potential energy, elastic potential energy, and chemical potential energy, depending on the type of energy involved. Potential energy is also measured in joules (J).
Kinetic and potential energy are both forms of mechanical energy, and they can be converted into each other. For example, when a rollercoaster car reaches the top of a hill, it has a maximum potential energy. As it goes down the hill, this potential energy is converted into kinetic energy. The total energy of the system (rollercoaster car and Earth) remains constant.
The amount of kinetic energy an object has is directly proportional to its mass and the square of its velocity. The amount of potential energy an object has depends on its position or state, and the type of potential energy involved. For example, the higher an object is lifted, the greater its gravitational potential energy will be.
The conservation of energy principle states that energy cannot be created or destroyed, only converted from one form to another. This applies to kinetic and potential energy as well - the total energy of a system remains constant, even as the energy is converted between kinetic and potential forms. This principle is a fundamental concept in understanding the behavior of energy in the universe.
