Watts (W) = joules (energy) per second
This content discusses the concept of energy transfer through power, measuring power in watts, and concentration in substances. It covers the definition, relation to work and energy, ways to increase power, and importance of concentration in solutions. Tangent, a mathematical term, is also explained along with its application in geometry. Explore the world of science in relation to these fundamental principles.

Science definition: Draw it The amount of energy transferred per second. Power Use it in a sentence/ equation Measured in: Work (joules) Power (watts) = Watts (W) = joules (energy) per second Time (seconds)
Power can be increased by Power is measured in With greater power, more _________ is transferred per second. Power is not energy. Power is the _______ of energy from one store to another.
I think this word meansthe number of particles or mass of a substance in a certain volume of liquid or gas Are there parts of the word I recognise? - con (together) e.g. construct - centrate (middle) e.g. centre An example is - A salt solution has a high concentration. The word in a sentence The gas particles moved from an area of high concentration to an area of low concentration. It is not about focussing on school work. It is not related to solids directly Why is this word important? - Tells us how much of a substance is in a certain volume How does this word fit with other words I know? Dilute Dissolve Solution Solute Solvent
Tangent - a straight line or plane that touches a curve or curved surface at a point. (noun) - The tangent touches the curved line. - What is the difference between the tangent and the chord? - His teacher often goes off on a tangent in lessons! From the Latin word tangens meaning to touch; to handle . How do the pictures relate to the word tangent ? Use the word tangent in 3 different sentences. Complete a Frayer Model for the word tangent .
