1. WORK O W K R

2. WORK

3. WHAT ARE THE COMPONENTS OF WORK?

4. FORCE

5. -Is measured in terms of Newton, or simply the product of an objects mass (Kg), and the acceleration due gravity (9.8 m /s Sq.)

6. DISTANCE

7. Refers to the length the object had been to, it is either a vertical or a horizontal manner.

8. WORK = X DISTANCE FORCE

9. Quantitatively; W = Fd F = W / d d = W / F

10. Where: W refers to (work) F to (force) and d (distance)

11. Problem #1: A metal box is being pulled by a boy to a distance of over 0.025 km, How much work is done if the force applied is 75 N?

12. Given: F = 75 N d = 0.025 m W?

13. Solution: W = Fd = 75 N (25m) = 1875 Nm

14. Problem #2: How high is a sack of cement taken if the force applied upon carrying it is 45N, and the approximated work done is 65Nm?

15. Given: F = 45N W = 65Nm d?

16. W=Fd d = W/F = 65Nm / 45N = 1.44 m
