Simple Machines | Physics | | Course Hero

Simple machines are devices that can be used to multiply or augment a force that we apply - often at the expense of a distance through which we apply the force. The word for "machine" comes from the Greek word meaning "to help make things easier.". Levers, gears, pulleys, wedges, and screws are some examples of machines.

What is an inclined plane simple machine? - eschooltoday

The Inclined Plane An inclined plane is a simple machine with no moving parts. It is simply an even sloping surface. It makes it easier for us to move objects to higher or lower surfaces than if we lifted the objects directly upwards. It is believed that ancient Egyptians used inclined planes to carry heavy stones to build pyramids.

What are Covalent Compounds? Definition, Formation, Properties

Covalent compounds are formed when the electronegativity values of the elements in a compound are identical or similar. As a general rule, atoms form covalent bonds if the electronegativity difference is less than 2 on the Pauling scale. If the difference in electronegativity is greater than two, the elements form ionic bonds. An example is CO 2.

A compound machine is two or more simple machines working together to make work easier. Scientifically speaking, a machine cannot do work — this ability is strictly limited to a source of energy, such as a human or a battery. Therefore, a machine does not enable you to do less work; rather it enables you to use less force.
