Using a graph, see how force increases proportionally with displacement, and how one can use the area under the graph to calculate the work done to compress the spring.

Check your understanding of spring force and Hooke's law in this set of free practice questions.

Review the key concepts, equations, and skills for spring potential energy and Hooke's law. Understand how to analyze a spring force vs. displacement graph.

This formula, when you have 1/2, the spring constant times the length that the spring has been stretched, that's the total amount the spring has been stretched.

Torque produced by gravity acts as the restoring force for the pendulum. Thus, the time period would be inversely proportional to the restoring force or the square root of gravitational …

Overview of key terms, equations, and skills for the simple harmonic motion of spring-mass systems, including comparing vertical and horizontal springs.

It tells you the amount of force that spring is gonna exert will be proportional to the amount that spring has been stretched or compressed from its equilibrium or natural length.
