Yes, walking is an example of mechanical energy because it involves the movement and interaction of the body's muscles and bones in order to change the position of the body. This movement is powered by the conversion of stored chemical energy in the body into kinetic energy.

A common example of mechanical energy is a moving car. The kinetic energy possessed by the car as it moves is a form of mechanical energy.
The type of energy involved with a person walking is mainly mechanical energy. This energy comes from the chemical potential energy stored in the person's body, which is converted to kinetic energy as they move.
An example of mechanical energy converting to electromagnetic energy is when a generator converts the kinetic energy from a spinning turbine (mechanical energy) into electrical energy (electromagnetic energy) through electromagnetic induction.
No, a forklift is a machine that uses mechanical energy to perform work, it is not an example of mechanical energy itself. Mechanical energy is the sum of kinetic and potential energy in an object or system due to its motion or position.
Physical energy is a broad term that encompasses all forms of energy present in a system, including mechanical energy. Mechanical energy specifically refers to the sum of potential and kinetic energy in a system due to its motion and position. Physical energy includes other forms such as thermal, electrical, and chemical energy.
