Hello! You look like Albert Einstein! Are you cutting your crazy hair?
I am not Albert Einstein, I just like my hair like this and I am a scientist.
I have a science project coming up and I was wondering if you could tell me about simple machines.
To start, a simple machine is the most basic device for making work easier. Some examples are incline planes, wedges, ans screws. Work is anytime you exert a force on an object that causes the object to move some distance, like when you pull books out of your backpack. An incline plane is a flat, sloped surface, for example, a ramp. A wedge is a device that is thick at one end and tapers to a thin edge at the other end. A screw is a simple machine that is related to the incline plane. A lever is a rigid bar that is free to pivot, or rotate, on a fixed point. And, last but not least, a fulcrum is the fixed point that a lever pivots around.
Wow! Good thing I was taking notes! Although I still don't really understand it.
I could give you some examples..
Some examples of wedges can be the blade of an axe or a knife. You can also make wedges thinner; like when you sharpen a knife. Screws, on the other hand, can be bolts, drills, or even jar lids! Some examples of levers can be things like catapults, seesaws, and scissors. Something cool about levers and fulcrums is that when you use a spoon, your wrist is the fulcrum and the spoon is the lever. When you turn your wrist, the spoon pivots, or spins, on the fulcrum.
