HOOKE’S LAW PRACTICE
1. A spring is stretched from its resting position a distance of 0.1 m. If the spring constant is k = 2.5 N/m, what
is the force being exerted on the spring?
2. If a spring is stretched a distance of 0.25 m with a force of 20 N, what is the value of the spring constant k?
3. If the spring constant k of a pogo stick is 3500 N/m and the weight of the person on the pogo stick is 700 N,
how much is the spring in the bottom of the pogo stick compressed?
4. What force is required to deform a spring with a spring constant of 1250 N/m by 2.5 cm?
5. A spring extends by 10 cm when a mass of 100 g is attached to it. What is the spring constant?
6. A spring with a spring constant of 0.70 N/m is stretched 1.5 m. What was the force?
7. How far will 20 N of force stretch a spring with a spring constant of 140 N/m?
8. A spring is stretched 0.15 m and the force was 1500 N. What is the spring constant?
9. A spring is stretched 0.75 m by using a force of 30 N. What is the spring constant?
10. A spring has a constant of 875 N/m. What force will cause this spring to stretch 4.5 m?
11. A spring with a spring constant of 25 N/m is stretched 65 cm. What was the force used?
12. A 25 N force stretches a spring 280 cm. What was the spring constant?
13. Using the graph above, (a) determine the spring constant, (b) write the Hooke’s law equation for this
spring.
14. The table below was data that was collected from 2 springs.
(a) Draw a force vs. length graph and place both springs on the same graph.
(b) Which spring is stiffer? How do you know?
15. The graph above is the data collected from two springs, a red spring and a blue spring.
Which spring has the greater spring constant? How do you know?
16. Using the graph above, (a) determine the spring constant, (b) write the Hooke’s law equation for this
spring.
17. The table below was data that was collected from a spring.
(a) Draw and label a force vs. length graph.
(b) What is the spring constant?
