OBJECTIVES:

• Write the definition for work; state the SI unit for work.

• Calculate the work done by a constant force when the force and displacement make an arbitrary angle with each other.

• Name and describe the two types of mechanical energy.

• Write the formulas for kinetic energy and gravitational potential energy using standard symbols.

• Calculate the potential energy of a single body in a uniform gravitational field.

• Calculate the change in kinetic energy or speed that results from performing a specified amount of work on a body.

• Calculate the work performed by the net force, or by each of the forces that make up the net force, on a body that undergoes a specified change in speed or kinetic energy.

• Apply the work – energy theorem to determine the change in a body’s kinetic energy and speed that results from the application of specified forces, or to determine the force that is required in order to bring a body to rest in a specified distance.

• Relate the work done by a force to the area under a graph of force as a function of position, and calculate this work in the case where the force is a linear function of position.

• Use integration to calculate the work performed by force F(x) on a body that undergoes a specified displacement in one dimension.

• Write the definition of power; state the SI unit of power.

• Calculate the power required to maintain the motion of a body with constant acceleration.

• Calculate the work performed by a force that supplies constant power, or the average power supplied by a force that performs a specified amount of work.

• Write an expression for power when an object moves with a constant speed due to a constant force.

• Distinguish between conservative and non-conservative forces.

• State the general relation between force and potential energy.

• Calculate a potential energy function associated with a force F(x).

• Given the potential energy function U(x), calculate the magnitude and direction of the force.

• Analyze a graph of potential energy as a function of distance to determine the turning points and to understand the significance of those turning points.

• State the generalized work-energy theorem and use it to relate the work done by non-conservative forces on a body to the changes in kinetic and potential energy of the body.

• Describe and identify situations in which mechanical energy is converted to other forms of energy.

• Recognize and solve problems that call for application both of conservation of energy and Newton’s Laws.
