Charecteristics of Potential Energy Question Choose the correct facts about Potential Energy Answers Option 1 A body releases its Potential Energy in the form of Kinetic Energy Option 2 Potential Energy is always positive Option 3 Gravitational potential energy of an object is a function of the height Option 4 Elastic PE is due to the state of Strain of Configuration Option 5 As a moving object slows down, its potential energy decreases Option 6 External force is the negative gradient of potential Feedback The potential energy of a system can be negative because its value is relative to a defined point. Energy conservation says KE decreases, PE increases Solution Correct Incorrect Correct Correct Incorrect Correct
Converting PE to KE Question When a body is released from a height h, the entire PE is converted to KE when it hits the ground The velocity of the body when it his the ground is Hint Answers Option 1 proportional to h Option 2 proportional to Option 3 inversely proportional to h Option 4 proportional to square of h Feedback Wrong Correct Option Wrong Wrong Solution Wrong (Feedback) Correct Option (Feedback) Wrong (Feedback) Wrong (Feedback)
