Velocity describes how an object’s position changes over time, including both speed and direction. It is a vector quantity, so you must specify direction along with magnitude....

Building a robotic arm turns mechatronics theory into a tangible, repeatable system that can position and manipulate objects. In its most common form, a robotic arm is a kinemat...

A slider crank mechanism converts linear motion into rotary motion, or vice versa, using a piston connected to a crank via a connecting rod. In an internal combustion engine, co...

Average velocity describes how quickly an object changes position over time, defined as total displacement divided by elapsed time. The equation for average velocity is v_avg =...

physics

For a projectile launched at speed v and angle θ, the height at which its speed equals 0.5v is h = (3 v^2 sin^2 θ) / (8 g). This is derived by equating the speed at height h t...
