... The work done on an object by a net force is equal to the change in the KE of the object. Work in direction of motion = Increase in KE Work in opposite direction of motion = Decrease in KE = Increase in Thermal Energy The Law of Conservation of Energy tells us that energy can be neither created nor ...

NOTES SPS7 Energy Transformation
... Energy can be defined as the ability to do work. If an object or organism does work (exerts a force over a distance to move an object) the object or organism uses energy. Because of the direct connection between energy and work, energy is measured in the same unit as work: joules (J). In add ...

Energy and Forces - No Brain Too Small
... Forces can make moving things go faster or slower. Forces can change the direction in which an object moves. When one moving object hits another they may both change direction. The force causing the change is called a contact force. When one force acting on an object is greater than the net effect o ...
