ICSE Class 8 Physics — Chapter Summary

Matter is anything that occupies space and has mass. It can be perceived by the senses and exists all around as living and non-living things. Matter is made of tiny particles called molecules, and the motion and attraction between these particles explain the solid, liquid, and gaseous states. Heatin

Physical quantities such as mass, volume, density, and relative density help describe matter in a scientific way. Density tells how much mass is packed into a given volume. Measurement of density is useful for regular solids, irregular solids, and liquids. The chapter also explains why some bodies f

Force is a push or pull that can change the state of rest or motion of a body, or change its size or shape. When a force acts on a body fixed at a point, it can produce a turning effect called moment of force. Pressure is the thrust acting per unit area, so the same force can create different pressu
