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 ...

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 ...

In this video, we explore the required velocity for an object to achieve a stable circular orbit around a planet. Learn about gravitational force, orbital mechanics, and how speed plays a crucial role ...
