The energy transformation that occurs when a person lifts a chair involves converting chemical energy from the food consumed into mechanical energy to move the muscles, which lifts the chair against the force of gravity.
The transformation energy of a person lifting a chair comes from the metabolic energy produced within the person's body, which is converted into mechanical energy to raise the chair against gravity. This energy is used to do work and overcome the force of gravity acting on the chair.
The energy used by a person to lift a chair is mechanical energy. This energy is converted from the chemical energy stored in the person's muscles to the kinetic energy of the chair and the person as they perform the lifting action.
The mechanical energy from the person hitting the drumstick is transformed into sound energy as the drum vibrates and produces sound waves.
You are using chemical energy produced in your muscles to lift a weight against gravity, which means the weight gains gravitational potential energy
Mechanical energy from the person pushing the button is converted into electrical energy, which activates the doorbell mechanism. The electrical energy then produces sound energy as the bell rings.

The energy source a person is using when lifting a chair is chemical energy stored in their muscles. When a person contracts their muscles to lift an object, chemical energy from food they have eaten is converted into mechanical energy to perform the task.
Chemical energy is transferred into kinetic energy. When a person jogs, motion is produced.
During skydiving, potential energy is transformed into kinetic energy as the person descends towards the ground. As the skydiver falls, gravitational potential energy is gradually converted into motion, increasing their speed until they reach terminal velocity.
The person is using mechanical energy to lift the chair. This involves converting chemical energy from the body into kinetic energy to move the chair against the force of gravity.

The person would be using mechanical energy to lift the chair. This energy is derived from the person's muscles contracting and exerting force to move the chair against gravity.
