Learning Objectives
- 7.01 Apply the relationship between a particle’s kinetic energy, ass, and speed.
- 7.02 Identify that kinetic energy is a scalar quantity.
7-2 Work and Kinetic Energy (1 of 16) Link to heading
Learning Objectives
- 7.03 Apply the relationship between a force (magnitude and direction) and the work done on a particle by the force when the particle undergoes a displacement.
- 7.04 Calculate work by taking a dot product of the force vector and the displacement vector, in either magnitude-angle or unit-vector notation.
- 7.05 If multiple forces act on a particle, calculate the net work done by them.
- 7.06 Apply the work-kinetic energy theorem to relate the work done by a force (or the net work done by multiple forces) and the resulting change in kinetic energy.

7-4 Work Done by a Spring Force (1 of 13) Link to heading
Learning Objectives
- 7.09 Apply the relationship (Hooke’s law) between spring force, the stretch or compression of the spring, and the spring constant.
- 7.10 Identify that a spring force is a variable force.
- 7.11 Calculate the work done on an object by a spring force by integrating the force from the initial position to the final position of the object or by using the known generic result of the integration.
