Waves are all around us. Light is a type of electromagnetic radiation that can be detected by the eye. It travels as a transverse wave. Sound waves are produced by a vibrating object. Everything that makes a sound must have a part that vibrates. Physical changes such as state change and dissolving are reversible, and there is no change in total mass when they happen. Temperature and heat are not the same. Heating matter makes the particles vibrate faster or move faster. Forces, Pressure and Speed. A force is a push or a pull.

All science games. Learn about the speed of sound in air and other states of matter, how an echo is made, and how we can calculate the speed of sound from echoes.

A moment is the turning effect of a force. Forces that create a moment act around a point called the pivot. The pivot is the point around which the object can rotate or turn. It makes calculations easier to try to measure the perpendicular distance between the line of action close line of action The imaginary line which shows which direction that a force is acting. This force has a turning effect on the door - a moment which causes the door to rotate around the hinges - the pivot close pivot A point around which something can rotate or turn. The size of a moment close moment The turning effect of a force. It is very important to remember that the distance from the pivot is measured at a right angle, or perpendicular close perpendicular At right angles to a line.

There are two main categories of forces - contact forces close contact force A force that act between two objects that are physically touching. You cannot see a force but you can see its effect. For example, when you apply a force to push a door open. Scalar quantities only have a magnitude close Magnitude The size of a physical quantity. Vector quantities are represented using arrows. The larger the arrow the greater the magnitude of the vector.

How to weigh a floating object without scales Learn how to find the weight of a floating object. The Sun is our nearest star. They need to be drawn and labelled correctly. The electromagnetic spectrum There are seven types of electromagnetic EM waves, which make up the electromagnetic spectrum. A Moon phase is the shape of the visible part of the Moon, and this changes gradually over the course of a lunar month. Social Studies History. Days, years and months are periods of time which are determined by the movement of Earth around the Sun, and the movement of the Moon around Earth. How to generate electricity.
