Founded by two veterans of Apple’s still-secret driverless car project, Aeva is a startup promising a different kind of lidar—one that can measure the velocity of objects in addition to their distance ...

This force will cause the cart to accelerate—in this case, to the left, or the opposite way it was heading, which is why it slows down during impact and even reverses direction. But what is the ...

Learn how to calculate the angular velocity required to create artificial gravity in a rotating system. This video explains the physics behind centripetal acceleration, rotation radius, and angular ...
