What happens to an object's potential energy as it gains kinetic energy?
As an object gains kinetic energy (movement), its potential energy decreases. This is because the energy is being converted from potential energy to kinetic energy. The total mechanical energy of the object (kinetic energy + potential energy) remains constant if no external forces are acting on the object.
Compare potential and kinetic energy?
Potential energy is energy stored in an object due to its position or state, while kinetic energy is the energy an object possesses due to its motion. Potential energy can be converted into kinetic energy when the object is in motion, such as when a ball is thrown in the air. The total energy of a system is the sum of its potential and kinetic energy.
What is the potential and kinetic energy of a system with moving parts called?
The potential and kinetic energy of a system with moving parts is called mechanical energy. Potential energy is the energy stored in an object due to its position or state, while kinetic energy is the energy possessed by an object in motion. The sum of an object's potential and kinetic energy is its mechanical energy.
Is mechanical energy found by adding an object's potential energy and kinetic energy?
Yes, mechanical energy is the total energy of an object due to its position (potential energy) and its motion (kinetic energy). It is calculated by adding the potential energy and kinetic energy of an object at a given moment.
Two examples of potential energy converted to kinetic energy?
A pendulum hanging still at its highest point (potential energy) is released, converting its potential energy to kinetic energy as it swings back and forth. An object held above the ground (potential energy) is dropped, converting its potential energy to kinetic energy as it accelerates towards the ground.
