potential energy and kinetic energy
The correct answer is potential energy and kinetic energy.
Mechanical energy is the energy that is possessed by an object due to its motion or its position. It's a sum of two main types of energy:
- Kinetic Energy: This is the energy of motion. Any object that is moving possesses kinetic energy. The faster the object moves, the more kinetic energy it has. The formula for kinetic energy is given by \(KE = \frac{1}{2}mv^2\), where 'm' is the mass and 'v' is the velocity.
- Potential Energy: This is the energy stored within an object due to its position or configuration. For example, a ball held high above the ground has potential energy due to its position in the Earth's gravitational field. This is often referred to as gravitational potential energy. Other forms of potential energy include elastic potential energy (stored in a stretched spring) and chemical potential energy (stored in chemical bonds).
Therefore, the total mechanical energy of a system is the sum of its kinetic energy and potential energy. Options 2, 3, and 4 represent other forms of energy, but they are not components of mechanical energy.
