Motion lesson 7

OUTCOME

By the end of the lesson you will be able to apply conservation of energy to solve a variety of problems

Engage

Energy in a mechanical system will transfer between kinetic and gravitational but the total mechanical energy of the system will be constant

LEARNING TASK

Explain

If a roller coaster (mass m) is released from rest at height h from its lowest point, use conservation of energy to find a relationship for the velocity v, when it reaches the bottom of the track
