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.

Introduction to forces. Learn about the different types of forces and the difference between contact and non-contact forces. Pressure is a measure of how concentrated a force is. The amount of pressure exerted on an object depends on the force applied and the surface area it is spread over. Force diagrams and resultant forces. Learn about drawing and interpreting force diagrams. Find out how to calculate resultant forces acting on an object. Find out more about the difference between motion and speed and how to use the speed equation.

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. Friction is a force that acts between two touching surfaces and prevents or resists them moving against each other. When an object moves through the air it experiences air resistance. This force acts against the direction of movement. When an object pushes on a surface like a table, wall or the ground, the surface pushes back on the object with a balancing force.
