  1. Force & Work Notes TEKS 6.8E investigate how inclined planes and pulleys can be used to change the amount of force to move an object TEKS 7.7A 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

  2. Essential Question How do you know when work is done?

  3. A force is any push or pull on an object.

  4. work. When a force is exerted that moves an object you do

  5. The force must be in the same direction as the object’s motion.

  6. No work is done when… …the force on the object is not able to move the object, so there is no motion. …the movement and the force are not in the same direction.

  7. Calculating Work Essential Question – How do you know the amount of work being done?

  8. The unit of measurement for work is Joules.

  9. The unit of measurement for force is Newtons.

  10. spring scale. The tool used to measure weight or force is a

  11. Work can be calculated using the following formula: W = F X dWork=ForceXdistance

  12. 20N 4 m How much work is done if a force of 20 Newtons moves a box 4 meters?

  13. 20N 4 m W = F X d W=20NX4m W=80 Joules
