Q1}SIMPLE MACHINE=A simple machine is a mechanical DEVICE that changes the direction or magnitude of a force.[2] In general, they can be defined as the simplest mechanisms that use mechanical advantage (also called leverage) to multiply force.[3] Usually the term refers to the SIX classical simple machines that were defined by Renaissance scientists

complex machine=complex machine is a machine made up of two or more simple machines that MAKE your work EASIER to do. There are six simple machines from which all complex machines are made. They include: The lever. The inclined plane.

MECHANICAL ADVANTAGE=Mechanical advantage (also written as MA in formulas) is the factor by which a machine multiplies force. The mechanical advantage of a machine can be used to find out how well a machine WORKS and whether it can perform a particular job.

Q2}work done = f × d

50×10 = 500

Q3} ma = fo/fa =10/4=2.5
