Spread the loveIn physics, displacement is a key concept that allows us to measure an object’s overall change in position. One way to determine such displacement is by analyzing a velocity-time graph.

Velocity-time graph Skydiver’s velocity-time graph If a velocity-time graph of the motion shows a rising or falling line, this means that the velocity is changing.

Velocity-time graphs are similar to speed-time graphs. The following velocity-time graph represents the motion of a bus which travels along a straight road, then returns in the opposite direction.

For robot manipulators executing specified tasks along predefined paths (for example, grinding, welding, and spraying), it is usually desired that the end effector possesses a uniform linear velocity ...
