How to Whirl a Squirrel off of a Bird Feeder

Now usually, a squirrel will jump off a bird feeder that starts to spin—but not the one in this viral video.But what is the force-paired object pushing on the squirrel?When you drop that apple, the gravitational force increases its speed as it falls, thus increasing its momentum.

Avast Antivirus Shuts Down Its Shady Data-Selling BusinessKudos this week to Motherboard and PC Mag, who jointly further exposed the shady practices of security company Avast.By the end of the week, Avast had decided to stop collecting and selling user data, and to wind down Jumpshot altogether.

Could You Bungee-Jump Using Only Magnets?

Could You Bungee-Jump Using Only Magnets?

That’s the premise behind this video of the supposed “first wireless bungee jump.” Let me be real clear: It’s a fake.As the cord stretches, it exerts an upward force on the jumper in the same direction that the ground would push.

Great Stunt, Spider-Man! Now Let's Fine-Tune the Physics

Now, if we put this vertical acceleration together with the fixed horizontal velocity , we get something special, called projectile motion. On the next jump, I get a vertical acceleration of –6.074, which is closer, but you can see that the fit is pretty janky.

The Physics of the Millennium Falcon's Jump to Hyperspace

The Physics of the Millennium Falcon's Jump to Hyperspace

To estimate the acceleration, we can look at the angular size of the back of the Falcon as it moves away. All I need to do is measure the position of the sides of the Falcon and use that to calculate the angular size in each frame of the video during the jump to hyperspace.

A Physics Analysis of Every Jedi Jump in All of Star Wars. For these Jedi jumps in Star Wars, it's plausible to estimate the distance scale by looking at things like Ewan McGregor (height of 1.78 meters) or Liam Neeson (height of 1.93 meters).

The Odd Physics of Rey's Backflip in Star Wars: Episode IX

The Odd Physics of Rey's Backflip in Star Wars: Episode IX

For Rey jumping over (I assume she makes it) a TIE fighter, I'm just going to look at her vertical motion. There is some type of TIE fighter zooming toward Rey. You would think her goal is to jump over the spacecraft, but who really knows.

The Physics of Building Jumps in The Matrix

The Physics of Building Jumps in The Matrix

If I assume he jumps like a normal human with an upward speed of 3 m/s (this would give a 0.6 second hang time), then the gravitational field would be 1.4 N/kg.

Here is the rule that I have for a jumping Captain Falcon: Yes, that seems like a crazy model, but when I run it I get the following plot (along with data from the video analysis).

But both Uber and Lime say they’ve been snubbed, and that they want to expand service to more lower income New Yorkers.A mock-up of Lyft's branded dockless bikes, which the company says it might deploy in cities all over the US.

Climate change warning: Sea levels rising even FASTER as ice caps melt

Climate change warning: Sea levels rising even FASTER as ice caps melt

GETTYA two metre jump could see a host of major cities be partially submergedCo-author John Fasullo, a climate scientist at the National Center for Atmospheric Research, said: "This study highlights the important role that can be played by satellite records in validating climate model projections.”If the calculations are correct, it would mean that sea levels could rise by almost one metre by 2100, which would be devastating for island countries around the globe.
