Simple Microscope The Structure of the Simple Microscope Describe the structure of the simple microscope A magnifying glass, an ordinary double convex lens with a short focal length, is a simple microscope. The reading lens and hand lens are instruments
Light is a form of energy which controls the sense of vision.
The Concept of Friction Explain the concept for friction Friction is the force which opposes (resists) motion of the body for example: If a block of wood is placed on a table it remains at rest Unless it is acted
Scalar and Vector Quantities Difference between Scalar and Vector Quantities Distinguish between scalar and vector quantities Scalar Quantities These are physical quantities which have magnitude only. Examples of scalar quantities include mass, length, time, area, volume, density, distance, speed, electric
