The # of times a machine multiplies the input Force

MA= output force/ input force

one of the basic machines that makes doing work easier

1. lever

2. Inclined plane

3. Wheel and axle

4. Pulley

5. Wedge

6. Screw

A machine that is made up of two or more simple machines

The science and technology of building electronic circuits and devices from single atoms and molecules

A machine that works automatically or by remote control.

A fixed point around which a lever rotates

A solid bar that rotates, or turns, around a fixed point (fulcrum);

It is between

the effort force and load.

Example: seesaw

• The load is in between the effort and fulcrum

Example: wheelbarrow

Fulcrum is near the effort force and load is at the other end

Example: fishing rod

A simple machine that is a sloping surface

■ A simple machine that is a wheel attached to a shaft, or axle

A wheel with a grooved rim that turns on an axle.

A simple machine that has a thick end and a thin end; used to cut, split, or pierce objects, or hold objects together.

A simple machine that is an inclined plane wrapped around a cylinder; used to raise and lower weights as well as to fasten objects

The force exerted on a machine.

The force exerted on an object by a machine

I was born in January 4,1643 in UK. I was an established physicist and mathematician, and famous for my law of gravitation, was instrumental in the scientific revolution of the 17th century. In 1687, I published my most acclaimed work, Philosophiae Naturalis Principia Mathematica. I died in London on March 31, 1727.

Among two spherical having uniform density is directly proportional; to the product of their masses and inversely proportional to the square of the distance between them.

It is denoted by g.

It refers to the acceleration that the Earth imparts to objects on or near its surface due to gravity.

In SI units it is measured in m/s2 or m-s-2 or equivalently N/kg or N-kg-1. It has an approximate value of 9.8 m/s2
