Lesson Plan: Friction Science
This lesson plan includes the objectives, prerequisites, and exclusions of the lesson teaching students how to describe the effects of friction on the motion and energy of objects.
Objectives
Students will be able to
- recall that friction is a force,
- recall that friction acts in the opposite direction to the direction of motion,
- recall that friction reduces the kinetic energy of objects,
- recall that friction between objects can increase their temperatures,
- recognize sources of friction,
- recognize methods for increasing or reducing the friction between two surfaces.
Prerequisites
Students should already be familiar with
- the fact that heating is the transfer of thermal energy,
- the term dissipation,
- the fact that a force acting on an object changes the velocity of the object.
Exclusions
Students will not cover
- any calculations,
- velocity-dependent friction forces.
