True: When an object is not moving but is at a height it has a high gravitational potential energy. , A hotter object has a greater thermal energy store than a cooler object. , Energy cannot be created or destroyed. This is called the conservation of energy. , An object that is moving very quickly has a high kinetic energy. , When a car rolls down a hill it transfers gravitational potential energy to a kinetic energy store. , The units of force are Newtons (N). , The units of work done are Joules (J). , Work done(J)= energy transferred (J). , False: When an object is not moving it has a high kinetic energy. , A cold object has a greater thermal energy store than a hot object. , Energy can be destroyed or created. , An object moving very quickly has a low kinetic energy. , When a car rolls down a hill it transfers kinetic energy to a gravitational potential energy store. , Work done= distance (m) divided by force (N), The units of work done are Newtons (N). ,
