In this physics lesson, we break down how the force of friction always opposes sliding motion, whether it’s static or kinetic friction. Through clear demonstrations, motion tracking, and connections to Newton’s Laws of Motion, you’ll see...

All the light that we see are electromagnetic waves. All different wavelengths are equivalent, except that waves of higher frequencies are more energetic. The speed of all these EM waves, however, is the...

Summary:

If you point a powerful laser at the moon, and spin it 100 times per second, the dot on the moon will move 3X the speed of light. This is ok. The maximum speed limit is not a limit with which...

How does the Earth's rotation affect the speed of an aircraft and duration of a flight? Why is it longer to fly east to west? How does the Coriolis Effect and Jet Stream affect this? Join us as we explore and explain this phenomenon!

This video discusses the concept of redshift and the expansion of the universe, starting with the discovery of the universe's expansion through the redshift of light from distant galaxies. It explains the three types of redshift: Doppler...

How a unique but simple experiment in the 19th century gave a new insight into the behaviour of sound waves. Physics - Waves - Learning Points. The Doppler Effect is when the pitch of a sound seems to change as it moves past. The...

The Doppler Effect is demonstrated. Animations are used to show the observed change in wavelength and frequency.
