planing writing of the double pages

The world of science is fun and full of interesting equation. For example E=MC2 (Energy = mass x time) an equation which helps to find the heat of the sun this is helpful. But back to the main subject PHYSICS!!! how fun with its many equations and its interesting ways of showing science through endless possibility. First the experiment will be measuring Newton how fun.

EQUIPMENT:
1.Newton meter
2. 10g weights
3. clamp stand

a Hold the newton meter vertically. There is no force pulling its spring (apart from the weight of the hook), so the reading must be zero. Make a mark on the blank strip that will be the 0 of your newton meter scale. 

b Pull on the spring with a force of 1 newton. On Earth, the weight of a 100-gramme mass is approximately 1 newton. So if you hang a 100-gramme mass from the newton meter, the Earth will pull it down with a force of about 1 newton. That is the force that stretches the spring. Make a mark on the blank strip that will be the 1 of the scale.

c Hang another mass from the newton meter. The force pulling the spring of the newton meter is now approximately 2 newtons. Make a 2 newton mark on your newton meter scale.

d Repeat this up to 10 newtons. You have now ‘calibrated’ your newton meter so that it has a scale for taking measurements.

e Take the masses off the newton meter and hang the unknown mass from it. Record the force of gravity (weight) that acts on this mass. You can now use your newton meter to measure any force, up to 10 newtons.
