5 cards from this section. Quick, good the night before a test.
What is kinetic energy?
Think about moving objects around you.
Define potential energy.
Consider an object sitting at a height.
What is the formula for kinetic energy?
Focus on the motion aspect of energy.
True or False: Potential energy can be transformed into kinetic energy.
Consider scenarios of falling objects.
A 1500 kg car is at rest at the top of a hill that is 20 meters high. Calculate its potential energy. Then if it rolls down the hill and reaches a speed of 25 m/s at the bottom, calculate its kinetic energy.
Use the formulas for both potential and kinetic energy.
A water balloon is thrown from a height of 5m. If it has a mass of 0.5 kg, calculate its potential energy before being thrown. What will be its kinetic energy just before it hits the ground?
Consider that energy is conserved through the fall.
