What is the conservation of energy principle?
Think about how energy behaves in a closed system.
Provide an example of kinetic energy.
Relate to any movement.
What does the conservation of energy state?
Think about the principle of energy in closed systems.
True or False: Kinetic energy becomes potential energy when an object is at rest.
Consider what occurs during motion.
An object is dropped from a height of 20m. Calculate the speed of the object just before it hits the ground (g = 9.81 m/s²).
Remember the formula for potential and kinetic energy.
In a roller coaster, the height at point A is 30m, at point B is 10m. Calculate the speed at point B assuming no friction.
Focus on how energy transitions between heights.
