Energy

Energy. Book Chapter 15. Energy. Work is a transfer of energy. Mechanical energy is when objects have the ability to do work. There are two types of mechanical energy: 1. Potential Energy (PE) 2. Kinetic Energy (KE). Kinetic Energy is energy in motion.

Types of Energy

Types of Energy. What is energy?. Energy is the ability to do work or cause change. Work is done when a force moves an object through a distance. Work is the transfer of energy . (The object that work is being done on gains energy) Both energy and work are measured in joules (J).

Definition of Work

Chapter 5. Section 1 Work. Definition of Work. Work is done on an object when a force causes a displacement of the object. Work is done only when components of a force are parallel to a displacement. Chapter 5. Section 1 Work. Definition of Work. Chapter 5. Section 1 Work.

Physics

Physics. Energy and Work. The Energy. We define energy the ability of a body or of a system to do work and the extent of this work is in its turn the energy measurement. Energy is an inherent, measurable property of matter belonging to the very existence of physical bodies.
