What is gravity?
This video considers peoples’ understanding of gravity and through these ideas shows that it is a force of attraction between masses. Some of the detail is covered in other Veritasium videos.
What is NOT random?
This challenging video takes a philosophical approach to discussing what information is. It begins by equating information to entropy. Entropy is explained as the degree of order or alternatively randomness that exists. Examples of ordered information are the arrangement of molecules in DNA, letters in words and...
What is quantum mechanical spin
This video explains the term spin. It introduces the idea of a magnetic dipole in electrons and shows how, in an external magnetic field, electron spins can be aligned or opposed (different quantum states).
However, when considering just two electrons coupled together the possible quantum positions becomes...
What is water made of?
This very basic video shows what people believe water is. It might be useful as a discussion point.
What powers Australia?
This is a video that asks young adults their opinion of nuclear power being used in Australia. 90% of Australia’s power derives from coal and gas. There are no nuclear power stations.
The comments from audience could be used to initiate similar discussions for the UK.
What's in a candle flame
This video uses two oppositely charged metal plates to demonstrate that a candle flame contains ions. Positive ions are attracted to the negative plate, while negative ions the positive plate. Even when the candle is extinguished, the smoke is attracted to both plates and so must also contain ions.
...When is a bungee jumper's acceleration max
The video asks students to predict when a bungee jumper experiences maximum acceleration. The answer is at the very bottom of the jump. This is often counter-intuitive as the velocity at this point is almost zero.
However, acceleration is the rate of change of velocity over time, a = Δv/Δt...
Where did the Earth come from?
The video begins by showing the many misconceptions that people have concerning the Earth’s formation. It then explains that the Earth was formed from elements formed in stars.
Where does the Sun get its energy?
The video begins by demonstrating the many misconceptions people have about the source of the sun’s energy. Using water-filled spheres, collisions between protons are modelled and the creation of energy and helium nuclei. The equation E=MC2 is introduced and is used to show that mass is converted into...
