Question

What are two forms of mechanical energy

Answer 1

Hey there! 

There are two different forms of mechanical energy: Kinetic energy and Potential energy. 

Kinetic energy is created by an object's motion. 
Potential energy is created by an object's position or its configuration. 

Thank you! 

Answer 2

A) Kinetic energy. It is a type of energy which depends on the mass and speed of a system:

$E_k = \frac{1}{2}mv^2$

b) Gravitational potential energy: This type of energy depends on the position (height) and mass of the system:

$E_p = m\cdot g\cdot h$
