1. Work
Work the transfer of energy using a force that causes the object to move in the direction of the force

2. Work & Kinetic energy “moving energy”
You can tell if an object has had work applied if it is moving in the direction of the force that was applied.

3. Equation for Calculating Work
Work = Force X distance
W= F X d

4. Equation for Calculating Work
Force is expressed in Newton’s (N)
Basic SI unit for distance is meter (m)
Work is expressed as Newton-meters in a unit called a joule (J)

5. Problem #1: How much work is done by a person who uses a force of 27
Problem #1: How much work is done by a person who uses a force of 27.5N to move a grocery cart 12.3m?

6. Step 1: Write down the equation needed to solve the problem.
W = F x d

7. Step 2: Insert all known measurements into the equation.
W = 27.5N x 12.3m

8. Step 3: Do the math to solve the equation
W = J

9. Step 4: Make sure that all of your numbers have the correct SI unit label and recheck your answers.
