Does mechanical energy of a coconut falling from a tree increases or decrease?
The mechanical energy of a coconut falling from a tree decreases. As the coconut falls, its potential energy (due to its height) is transformed into kinetic energy (due to its motion). Therefore, the total mechanical energy (potential energy + kinetic energy) decreases as the coconut falls.
What are the two types of mechanical energy?
The two types of mechanical energy are kinetic energy, which is associated with the motion of an object, and potential energy, which is associated with the position or configuration of an object.
If gravity is the only force present what is the total mechanical energy of a book falling off a shelf at a time when its potential energy is 50 J and its kinetic energy is 60 J?
The total mechanical energy of the book falling off the shelf is the sum of its potential energy and kinetic energy. Therefore, the total mechanical energy is 110 J (50 J potential energy + 60 J kinetic energy).
Is falling rocks mechanical energy?
No, falling rocks would typically be considered potential energy as they have the potential to do work due to their position above ground. Once they start falling, they convert potential energy to kinetic energy.
If an object's mechanical energy is equal to its potential energy how much kinetic energy does it have?
Mechanical Energy= Potential energy+ Kinetic energy, so for the mechanical energy to be equal to be potential energy, the kinetic energy must be 0.

At a certain point of the Kinetic energy of a falling Apple is 5.2 J and it's potential energy is 3.5 j what is the mechanical energy?
The mechanical energy is the sum of the kinetic and potential energy. In this case, the mechanical energy would be 5.2 J + 3.5 J = 8.7 J.
Potential energy plus kinetic energy equal what?
Mechanical energy is equal to potential energy plus kinetic energy in a closed system. The total mechanical energy is conserved.
The sumof the kinetic and potential energies of a freely falling body is?
The sum of the kinetic and potential energies of a freely falling body is constant and equal to the total mechanical energy. This is a result of the conservation of energy principle, where the body's potential energy is converted into kinetic energy as it falls, keeping the total energy constant.
If an object's mechanical energy is equal to potential energy how much kinetic energy does the object have?
Mechanical energy is defined as the SUM of potential energy plus kinetic energy. If all of its mechanical energy is potential energy, it follows that it has no kinetic energy.

What does potential energy and kinetic energy have to do with mechanical energy?
Potential energy and kinetic energy are components of mechanical energy. Potential energy is the energy stored in an object due to its position or configuration, while kinetic energy is the energy an object possesses due to its motion. Together, potential and kinetic energy make up the total mechanical energy of a system.
Can an object have both mechanical and kinetic energy?
Yes, an object can have both mechanical energy and kinetic energy. Mechanical energy is the sum of an object's potential energy and kinetic energy. Kinetic energy is the energy an object possesses due to its motion, whereas potential energy is the energy stored in an object due to its position or state.
