Scientists joke





v What are Newton's laws of motion?

It's not only thick people who have trouble understanding Newton's laws. But although they appear complicated, they are actually very simple. However, first we must get to know four scientific terms:

Force: When you kick your sister in the shin, you are using force.

Mass: If she is fat she has lots of mass.

Inertia: Being fat, she will not be able to chase you. She has inertia.

Energy: Every time you kick her, molecules in the form of waves pass from your foot to her shin. This is energy. There can be lots of energy, like a nuclear bomb, or a tiny amount, like when one of your brain cells dies.

Newton's First Law If something is not moving it will stay where it is. Kick your sister in the shins. Go on, do it now. You will see that she reacts. Let's just think about what happened there. If you hadn't kicked her, she would have stayed where she was, probably sitting in front of the TV eating cakes. Hence, the first law is proved. Newton discovered this law when an apple fell on his head. To this day it is know as Newton's Apple Law.
Newton's Second Law Every action results in a small loss of energy. You know how when you do a lot of exercise, you run out of breath? Well, this is proof of Newton's second law. This may seem simple but it has terrible consequences for the universe. You see, if the universe runs out of energy soon, everyone in it, including you and your family, will just waste away into nothing! But don't worry too much — scientists don't think this will happen in your lifetime.
