ICSE Class 6 Physics — Flashcards for Quick Revision

A: Matter is anything that occupies space and has mass. Examples: book, water, air. All things around us—living and non-living—are made of matter.

A: The three states of matter are: Solid, Liquid, and Gas. Example: Ice (solid), Water (liquid), Steam (gas).

A: Solids cannot be compressed easily because their molecules are tightly packed with very little space between them. The intermolecular forces are very strong, so the particles cannot be pushed closer.

A: A physical quantity is any quantity that can be measured. Examples include length, mass, time, and temperature. These are measured using standard units like metre, kilogram, second, and degree Celsius

A: Our senses like touch or sight are subjective and can vary from person to person. For example, one person may feel water as warm while another feels it as hot. So, we use standard instruments like rul

A: Every measurement requires: (1) A number (n) that tells how many times, and (2) A unit (u) which is a standard of comparison. So, Measurement = n × u. For example, 5 metres means 5 times the unit 'met

A: Force is a push or pull acting on an object. It can change the state of motion or shape of the object. Example: Pushing a door to open it.

A: 1. Pushing a trolley at the market. 2. Pushing a car that has stopped working.

A: 1. A bull pulling a cart. 2. A person pulling a luggage trolley at the railway station.
