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.
The potential energy of a freely falling body decreases continuouslyWhat happens to the loss of potential energy?
It becomes kinetic energy. And as an object goes up against gravity, it gains potential energy and loses 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.
What does potential energy and kinetic energy have to do with mechanical energy?
Potential and Kinetic Energy add up to produce mechanical energy.

What is the definition of mechanical energy?
Energy an object has because of its motion or position. A combination of kinetic and potential energy resulting from the force of gravity and/or the movement or release of a machine component, such as a spring, clamp, or wheel. The total mechanical energy is the sum of the potential and the kinetic energy.

What type of energy is kinetic and potential?
Kinetic and potential energy are types of mechanical energy.
Is a falling ball potential or kinetic energy?
it is kinetic because it involves releasing the energy.
Can objects mechanical energy be equal to its gravitational potential energy?
Yes. Mechanical energy is the sum of potential energy and kinetic energy; this includes gravitational potential energy.
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.

Does gravity cause kinetic energy to change into thermal energy?
No. Friction with the air does with an object in free fall in the earth's atmosphere. Gravity causes a falling body to accelerate so it changes potential energy into kinetic energy.
