Question 1.
What are the two main types of energy in waves?
Show hintHide hint
Think about what energy comes from motion vs. position.
Question 2.
In which direction does potential energy always act?
Show hintHide hint
Consider height and gravitational effects.
3Question 3.
What is the formula for calculating kinetic energy in waves?
- KE = 1/2 mv²
- KE = mv
- KE = mgh
Show hintHide hint
Think about what energy relates to motion.
4Question 4.
Is the total energy in waves doubled when we double the amplitude?
- True
- False
Show hintHide hint
Review how changes in amplitude influence total energy.
Question 5.
Calculate the energy contained in a wave with an amplitude of 3m. Use γ as 9.81 kN/m³.
Show hintHide hint
Don’t forget to square the amplitude first!
Question 6.
Discuss the effects of wave energy on coastal infrastructure during a storm, considering variable wave heights.
Show hintHide hint
How does energy change with height and wave strength?
