3 cards from this section. Quick, good the night before a test.
What is the basic formula for kinetic energy?
Think about the factors affecting energy when an object is in motion.
What does potential energy depend on in the context of water waves?
Refer back to the discussion about wave height and displacement.
What does kinetic energy depend on?
Remember the kinetic energy formula.
True or False: Potential energy in waves is zero when waves are absent.
Consider what happens to energy when waves are not present.
A wave with an amplitude of 1.5 m travels through water with a density of 1000 kg/m³. Calculate the total energy per unit surface area at the crest and trough.
Use the total energy formula appropriately.
If a water wave has a kinetic energy of 500 J and increases in speed, resulting in a final velocity of 8 m/s, what was the mass of the water that caused this energy?
Remember to rearrange the kinetic energy formula correctly.
