Conduction, convection and radiation are all ways in which heat is transported. How does each work, and what are they useful for? Physics - Energy And Radioactivity - Learning Points. The three types of heat transport are conduction,...

Sound waves move through different mediums at different speeds, but why is this? What factors affect the speed of sound? Physics - Waves - Learning Points. Speed of sound depends on many different factors. Temperature, elasticity and...

Sounds can vary greatly: extremely quiet or deafeningly loud, high and shrill to low and booming. Why are they so different? Physics - Waves - Learning Points. Sound is a vibration passed to and fro along particles forming a wave. It can...

We compare the density of oil, salt water and fresh water using displacement tanks. Equally weighted measuring cylinders are placed into the three liquids and the amount of water displaced is collected for comparison. Physics - Forces -...
