Tesla Cybertruck Vs. a Ford F-150: It's All About Friction

Now it's this video of a tug-of-war between the Cybertruck and a Ford F-150 .It's all about friction and the interaction between the tires and the road.The Tesla Cybertruck, with its steel outer shell, is probably more massive than a Ford F-150.Let's be clear.

Google's New Gesture Controls Aren't Just for the Pixel

When Google's next flagship smartphone, the Pixel 4, arrives this fall, it will respond to a series of gesture interactions—a pinch of the fingers, or a wave of the hand—without the user ever needing to touch the screen.

An Electric Pickup Truck Really Could Pull a Freight Train—Here's How

Here is a force diagram for a tiny object pulling a massive object with no friction. For the train (object B), a frictional force is pulling to the right.

R.I.P., Anki: Yet Another Home Robotics Company Powers Down

Anki, maker of Vector, a toy-like autonomous countertop robot, is shutting down, and hundreds of people are losing their jobs. It’s a brutal answer to a question we asked last summer : Sure, home robots like Vector are cute, but is this something consumers actually want?

Estimate the Pulling Force of Boston Dynamics' Robo-Dog Army

That's pretty close to the estimated friction from the robot dogs (maybe my values for the coefficients are off).What about pulling a truck uphill? They also have a decrease in the frictional force needed to pull the truck up the incline.

A Magic Wand? Nope, Just Good Ol’ Fashioned Physics

What happens if I hang a neutral object from the string and bring the positively charged PVC pipe? These moving electrons experience an attractive force from the positive charges on the PVC and thus move to the right side of the metal (as seen in the diagram).
