What is Work?

Objectives:
Contrast situations where work is done with different amounts of force to situations where no work is done such as moving a box with a ramp and without a ramp, or standing still.
Explain how inclined planes can be used to change the amount of force required to move an object.
Calculate WORK by multiplying amount of force by distance displaced.

PowerPoint Presentation includes the following:
Part 1: What is Work?
Students will analyze different situations to determine whether or not work was done.
Includes –
yes/no response card template to be used during whole group instruction.
Interactive student worksheet aligned with PowerPoint presentation.
Part 2: Calculating Work
Students are introduced to the formula Work = Force X Distance.
Includes –
Animated problem solving for guided practice.
Interactive worksheet aligned with PowerPoint Presentation.
Part 3: Work and Inclined Planes
Students will analyze ramps with different angles to determine how they affect force, distance, and the amount of work done.
Suggestion: This part of the lesson would also be appropriate to use after a hands-on activity over the same concept.
Includes –
Guided notes describing the relationship between inclined planes and work.
Practice problems comparing different angles of ramps.
Interactive worksheet aligned with PowerPoint Presentation.
Exit Ticket

Identifies opportunities for reinforcement.
Includes –
Exit Ticket template for students to record their responses.
