Conservation of Energy SPH3U
The Law of Conservation of Energy “For an isolated system, energy can be converted into different forms, but it cannot be created or destroyed.”
The Law of Conservation of Energy “For an isolated system, energy can be converted into different forms, but it cannot be created or destroyed.” No external force is doing work on the system.
The Law of Conservation of Energy “For an isolated system, energy can be converted into different forms, but it cannot be created or destroyed.” For example, gravitational potential energy may be converted to kinetic energy.
Conservation: Example A ball is launched at 15 m/s horizontally from a ledge 15 m above the ground. What is the speed of the ball when it lands?

Friction causes kinetic energy to transform into thermal energy Friction causes kinetic energy to transform into thermal energy. Example: A 20-kg curling rock slides in a straight line for 30 m. The coefficient of kinetic friction is 0.1. How much thermal energy is produced during the slide?
Example: A 20-kg curling rock slides in a straight line for 30 m Example: A 20-kg curling rock slides in a straight line for 30 m. The coefficient of kinetic friction is 0.1. How much thermal energy is produced during the slide? Therefore 600 J of thermal energy was produced.
