name of the type of energy transfer when the object is pushed
mechanical
name of energy transfer which happens when an object gives out light
radiation(waves)
what is the name for the rule “energy cannot be created or destroyed, only transferred”
law of conservation of energy
write the equation which links distance, force and work done
work done = force x distance
