They may be inevitable OR they may simply be the outcome

Newton’s Law of Universal Gravitation can be summarized as “all mass attracts all other mass.” But if this is true, why don’t we notice the gravitational force of attraction between everyday objects? The reason is because the gravitational force is quite weak.

It’s the most abundant liquid on the planet and by weight we are about 60% water. But do we know what it is made of?

The Mars Helicopter, Ingenuity aims to make the first powered flight on another planet when it takes off on Mars. It has now landed and safely checked in with the rover. It should detach and fly within the first 30-60 days of the mission. I learned a lot getting to visit the drone right before

Key aspects of pyramid construction from quarry to completion. Check out Audible: http://bit.ly/AudibleVe Live show in Alabama: http://bit.ly/VeRAOI The most common misconception about the pyramids is that they were built by slaves. Recent archeological evidence suggests they were instead constructed by paid workers. Some may have performed this work as a form of tax payment

In a candle flame there are electrically charged particles, which you can pull apart using an electric field.

When the rope becomes taut, the force on the jumper is mainly his weight downwards, plus a bit of air resistance up. Therefore his speed is increasing nearly as much as it did when he leapt off the platform. So this is not the greatest acceleration of the jump.

http://www.abc.net.au/catalyst/team/default.htm I have been working with Catalyst on ABC1 to bring some Veritasium to Australian TV. In this segment I ask why astronauts in the space station are weightless. The most common answer is because there is no gravity in space. But of course there is gravity in space, especially where the space station is

This is not just true of slinkies – if you release a steel rod from the top, the top really starts falling before the bottom. If you hit a tennis ball with a racket, a wave has to travel from the strings to your hand before you feel it – and the ball is well

Will the spool go to the right, to the left, or does it depend on how the rope is pulled?

How do you measure big forces accurately? By calibrating your force transducer on the world’s biggest weight – 1,000,000 pounds of force. This machine ensures planes don’t break apart, jets provide required thrust, and rockets make it to their destination. Thanks to the people at NIST for showing me around: Rick Seifarth and Ben Stein.

At the jumper’s fastest point, the acceleration is by definition zero. That is because the jumper is going from speeding up to slowing down. At this instant then there is no change in the jumper’s velocity. This is counter-intuitive for a lot of people because it’s easy to confuse velocity with acceleration. Velocity is how

The aurora borealis or northern lights is one of the most spectacular natural displays on the planet. Theories about its origins have been debated for centuries and common misconceptions persist that the aurora is the sun’s rays scattered off ice crystals in the high atmosphere. In truth, the light is created more than 100km above

When a tube spins with an X and an O labelled at either end, why do we see only one letter during the rotation?

On mobile, click here for the answer: http://www.youtube.com/watch?v=qQCVnjGUv24 When ice is put under pressure, its melting point decreases. When that pressure is removed it goes back to being solid. This process is known as ‘regelation’. In this experiment regelation of ice is attempted with copper wire and fishing line of the same diameter. Which will

When is the acceleration (rate of speeding up or slowing down) greatest during a bungy jump?

How do our eyes scan across a landscape? Contrary to popular belief, they don’t scan smoothly across a scene, they observe a series of images. The eye is capable of panning smoothly however. If something moves in your field of view, your eyes track it smoothly. This has an important effect on our perception of
