3.3 Work

The kinetic energy of an object is given by: The gravitational potential energy of an object in a uniform gravitational field is given by: When an object falls through a gravitational field, GPE is converted to KE. When it reaches the ground, its GPE is 0 and its KE...

Work done is equivalent to the product of the force and the direction moved in the direction of the force. W=Fx Work done has the unit Nm or joule. It is also equivalent to energy transferred (energy is the capacity to do work).  If the force is applied at an angle to...
