Acceleration – an object accelerated by a constant force. When an object is accelerated by a force, there is a transfer of energy. Firstly, energy is required to accelerate the object; this could be chemical, thermal or electrical (the situation will determine the specific type of energy). This energy will then be converted into kinetic energy (used to accelerate the object).
