8. DO NOW
Calculate the potential energy of a bird sitting on a tree limb. The mass of the bird is 0.1 kg and it is 5 m off the ground.
What is the kinetic energy of a 2000 kg car that is traveling at 10 m/s?
Are you really doing work when you do your science homework?

9. 8.1 Work
In science, work is a form of energy you either use or get when a force is applied over a distance.
You do 1 joule of work if you push with a force of 1 newton for a distance of 1 meter.

10. 8.1 Work
When thinking about work, remember that work is done by forces that cause movement.
If nothing moves (distance is zero), then no work is done.

11. 8.1 Work
Force (N)
W = F x d
Work (joules)
Distance (m)

12. 8.1 Work and energy Doing work always means transferring energy.
The energy may be transferred to the object you apply the force to, or it may go somewhere else.

13. 8.1 Work and energy
You can do work to increase an object’s potential energy.
Then the potential energy can be converted to kinetic energy.

14. 8.1 Work
A raised object’s potential energy equals the amount of work it can do as it moves down.
The amount of kinetic energy an object has equals the amount of work the object can do by exerting force as it stops.

15. 8.1 Work
If force is equivalent to the weight of the object in newtons, and
height (h) is equivalent to distance (d),
Then multiplying the weight by height gives you the amount of work the object can accomplish as it moves down (as well as its potential energy).

16. 8.1 Work
Force A does no work because it does not cause the block to move.
Force B is applied at an angle to the direction of motion, so only part of force B does work.
The most effective force to move the block is force C.

17. Solving Problems
How much work is done by a person who pulls a cart with a force of 50 newtons if the cart moves 20 meters in the direction of the force?

18. Looking for: Given: Relationships: Solution Solving Problems
…work done by person
Given:
…force = 50 N (forward);
…distance = 20 m
Relationships:
Work = force x distance
Solution
50 N × 20 m = 1,000 joules.
