Word Problem Instruction: On your answer sheet solve the given word problem involving Gravitational Potential Energy. Identify the given in the problem, what is ask, and show your complete solution. 1. A 550-kg roller coaster car starts from rest at 50 meter above the ground. Calculate the change of gravitational potential energy at the end of the ride when it is now 2 meters above the ground? 2. Refer to problem 1, what would be the amount of KE if the coaster is already at 2 meters above the ground? 3. Does the change of gravitational potential energy depends on the path followed in moving between those position?

Instruction: Provide the possible explanation to the given situation based on the learned concepts in the discussion above. Bases for rating answers: 5 points - discussed well with physics concepts clearly explained 3 points - discussed well but physics concept is vague 1 point - tried to answer 1. Why are racing cars are built broad and low? 2. The legs of a baby's highchair are set wide apart, why do you think so? 3. Why is it that luggage compartment of a tour bus is located at the bottom and not on the roof? 4. If two objects collide and one initially at rest, is it possible for both to be at rest after collision? Is it possible for one to be at rest after the collision? Explain
