Tutor description

• Work can be defined as the application of a force over a distance. In other words, work is the use of a force to move an object a certain distance. • The equation for work done is: W = Fs • where W is work done, F is force in newtons (N) and s is the distance the object moved in metres (m). Work is measured in joules (J), which is equivalent to one newton per metre.

SCIENCEEnergy, Force & MotionWorkcan be defined as the application of a force over a distance. In other words, work is the use of a force to move an object a certain distance. The equation for work done is: W = Fswhere W is work done, F is force in newtons (N) and s is the distance the object moved in metres (m). Work is measured in joules (J), which is equivalent to one newton per metre.Work takes on many forms. It can be most easily seen when an object is moved from one place to another. Work is also taking place, however, when an object is being heated or changes state. In these cases, the work takes place on a particle level. As particles move more quickly, the object heats up and changes state.Energyis the ability of an object to change the velocity, location, shape or state of another object. Some definitions of work state that it is a transfer of energy from one object to another. Like work, energy is measured in joules. There are two main types of energy: kinetic energy and potential energy.Kinetic energyis the energy found in objects that are in motion. Kinetic energy is often used to change the speed or shape of another object. A billiard ball being hit by another billiard ball, for example, shows kinetic energy being used to change the speed of another object. Another example of kinetic energy doing work is when two cars collide with one another and their shape is changed.Potential energyis energy that is stored within an object. There are
