1. What is kinetic energy and how does it differ from potential energy? 2. What some specific examples of kinetic energy?

3. What are some examples of kinetic energy being transformed to potential energy?

4. What is the relationship between net force applied, mass, and change in the motion of an object?

5. Using the law of conservation of energy, explain in detail how the kinetic energy is transformed into potential energy on a roller coaster. Be sure to explain the differences and similarities between kinetic and potential energy in your response.

As part of your daily workout, you lie on your back and push with your feet against a platform attached to two stiff springs arranged side by side so that they are parallel to each other. when you push the platform, you compress the springs. you do an amount of work of 79.0 j when you compress the springs a distance of 0.230 m from their uncompressed length. (a) what magnitude of force must you apply to hold the platform in this position? (b)how much additional work must you do to move the platform a distance 0.230 m farther? (c) what maximum force must you apply to move the platform a distance 0.230 m farther?
