Force & motion
Your always moving
A little gist
Did you know that everything is moving even though it's not moving? Even your moving because you live on earth and earth orbits every second of the day. There is also many laws of motion from the famous Issac Newton. For example, for every actio, there is an equal and opposite reaction.
Some simple machines
Pulley
A pulley is one of many simple machines. The pulley consists of a rope or string and a special wheel that the string or rope goes through.
Inclined plane
An inclined plane is a block of something that has a edge that lets the object go onto and has a thick end that help it get up stairs or a escalator.
Screw
A screw that you put into wood to hold something is basically a bunch of miniature inclined planes that are working together to turn.
Guaranteed to make the work easier.
Frequently asked questions
A lot of people always ask, how does it make work easier? Well it make the work easier because it helps you lift things up without using a lot of strength.
Newtons laws of motion
Law of inertia: objects at rest will remain at rest and objects in motion will stay in motion unless acted upon by an outside force.
F=ma: the greater the force, the greater the speed
The action-reaction law: for every action, there is an equal and opposite reaction.
