Learning Targets

Students should understand the concept of potential energy, so they can:

(29) Write an expression for the force exerted by an ideal spring and for the potential energy of a stretched or compressed spring.

(30) Calculate the potential energy of one or more objects in a uniform gravitational field.

Students should understand the concepts of mechanical energy and of total energy, so they can:

(31) Describe and identify situations in which mechanical energy is converted to other forms of energy.

(32) Analyze situations in which an object’s mechanical energy is changed by friction or by a specified externally applied force.

Students should understand conservation of energy, so they can:

(33) Identify situations in which mechanical energy is or is not conserved.
