Read each question carefully and answer to the best of your ability. Show all your work for calculation problems.
1. Which of the following best describes Hooke's Law?
Force is proportional to acceleration.
Force is proportional to the extension or compression of a spring.
Energy is conserved in all systems.
Work done is equal to the change in kinetic energy.
2. What is the formula for spring potential energy?
PE = mgh
KE = 1/2mv^2
PE = 1/2kx^2
F = ma
3. According to Hooke's Law, the restoring force of a spring is directly proportional to its .
4. The spring constant (k) is a measure of the of a spring.
5. A spring has a spring constant of 200 N/m. If it is stretched by 0.15 meters from its equilibrium position, calculate the force exerted by the spring. (Show your work)
6. Explain the relationship between work done on a spring and the potential energy stored in it.
7. Observe the diagram below showing a spring in different states. Answer the questions that follow.
a) In which state (compressed or stretched) does the spring have more potential energy?
b) If the spring constant remains the same, what factor primarily affects the amount of potential energy stored?
8. Hooke's Law applies to all materials, regardless of how much they are stretched or compressed.
True
False
9. The units for spring potential energy are Joules (J).
