If I have ___ x 2 meters= 10 joules, How many newtons do I have?
300
Force and distance.
In order to have work, what two elements do you need?
300
Answers may vary.
Give us two examples of work:
300
apple
What piece of fruit landed on my handed supposedly?
300
move an object
To do work, a force must be exerted to...
400
No.
If I have a force but no distance, do I have work?
400
Yes.
Example:
30 Newtons X .5 meters= 15 Joules
30 Newtons X 1 meter= 30 Joules
If you double the distance, do you double the work?
400
No, he did not, he was a child prodigy.
Did he go to school?

1. an object at rest will stay at rest unless acted upon by an outside force
2. inertia
3. an object in motion will stay in motion unless acted upon an outside force.
What is the three things Isaac Newton created?
400
the more work you do!
Scientists know that the great the distance an object is moved...
500
Yes, if the force is doubled, then the work is doubled.
Example:
10 N x .5 meters= 5 Joules
20 N x .5 meters= 10 Joules
If I double the force, is the work doubled?
500
Yes, turning the pages is working because the force of you fingers is pushing the pages a distance.
HOWEVER, "holding" a book for 2 hours is NOT work!
Is reading book work? Why/Why not?

Found on a spring scale under "N" discovered by Isaac Newton, used to measure the amount of force.
What is the definition of a newton?
500
energy
What is needed to both apply a force and to make machines work?
