[BLANK]
Kristina demonstrates a toy for her younger brother. The steps to operate the toy are listed below.Step 1. Push the toy down.Step 2. A spring compresses.Step 3. Release the toy.Step 4. The toy jumps into the air.
Every spring has an equilibrium position. Which statements describe a spring at its equilibrium position? Check all that apply.
An eagle that has a mass of 4.5 kg is spotted 5 m above a lake. It flies up to its nest in a tree at a height of 25 m.
A compressed spring has 16.2 J of elastic potential energy when it is compressed 0.30 m. What is the spring constant of the spring?
An object that is 0.5 m above the ground has the same amount of potential energy as a spring that is stretched 0.5 m. Each distance is then doubled.
Which describes how the spring constant affects the potential energy of an object for a given displacement from an equilibrium position?
Doubling which quantity would cause the largest increase in a spring’s elastic potential energy?
Lamar writes several equations trying to better understand potential energy.
How does the work needed to lift an object and the gravitational potential energy of the object compare?
