👉 Learn how to determine the transformation of a function. Transformations can be horizontal or vertical, cause stretching or shrinking or be a reflection about an axis. You will see how to look at an equation or graph and determine the...

It’s no surprise that forces are everywhere! But how do we work out which forces are important, and which ones can be ignored? This lesson will distinguish between external and internal forces, before diving into more examples of contact...

Describe transformations of a function in function notation

From a tuning fork, to a speaker in slow motion, this is a close look at what sound is. Both linear and spherical wave fronts are animated. The human audible range is demonstrated.

Web development is moving fast and to keep up to mark, you need a technology stack that is . The MEAN stack includes MongoDb, Express, Angular, and Node.js. These tools provide a rich environment to build advanced web...

Waves are vibrations that transfer energy from place to place without matter being transferred. Think of a Mexican wave in a football crowd: the wave moves around the stadium, while each spectator stays in their seat only moving up then...

In chemistry we talked about the first law of thermodynamics as being the law of conservation of energy, and that's one way of looking at it, but physicists like doing math more than chemists do, so let's talk about the first law in...

This video discusses the properties that all waves have in common, including amplitude and wavelength. It also demonstrates how to calculate the speed of a wave using the equation v = Fλ, where v is the wave speed, F is the frequency in...

Describe transformations of a function

This is a video discussing the differences between beams and columns in structural engineering. The video explains that while all columns are beams, not all beams are columns, as columns can only experience compression while beams can...

This video reviews what harmonic motion is then provides definitions of all the components of the wave. Real world examples of simple harmonic motion are shown. Students will learn how to calculate frequency using a pendulum and a spring.

Helping children relate to the topics they study is what the Real World Science series of videos does best. Real World Science: Sound helps students learn the principles of sound, the range of human hearing and significant terms, as they...

Four mechanical wave graphs are introduced and used to understand and demonstrate transverse waves, longitudinal waves, wavelength, and period.

This video explores the characteristics of waves. It explains the speed of waves, how this value is calculated and the four basic interaction between waves. Other terminology includes: vibration, crest, trough, amplitude, wavelength,...

Upon viewing the The Nature of Waves video series, students will be able to do the following: Define waves as traveling disturbances that carry energy through matter or space. Explain that waves do not actually move matter. Instead,...
