When a person lifts a chair, they use mechanical energy from their muscles that is converted into potential energy as the chair is raised against gravity. The person's muscles do work on the chair to overcome gravity, increasing the chair's potential energy.
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 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 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.
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 is using mechanical energy to lift the chair. Mechanical energy involves the kinetic energy of moving the chair and the potential energy stored in the chair due to its position relative to the ground.

The person is using mechanical energy to lift the chair. Mechanical energy involves the kinetic energy of moving the chair and the potential energy stored in the chair due to its position relative to the ground.
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.
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.
When a person lifts a chair, they are expending mechanical energy to overcome the gravitational force acting on the chair. This mechanical energy is transferred from the person's muscles to the chair, allowing it to be lifted. Additionally, there may also be some heat energy generated due to friction between the person's hands and the chair.
the lifting chair is on the ski lift
You are using chemical energy produced in your muscles to lift a weight against gravity, which means the weight gains gravitational potential energy
Chemical energy from the person's muscles is turned into potential energy.
Since a chair is not intended to be used for moving or lifting it cannot be considered a machine at all.
