linear motion
Movement without curves
Linear motion is movement along a straight line, as opposed to circular or rotational motion.
A car traveling on a straight highway, a ball dropped from a roof, or a train on straight tracks all demonstrate linear motion.
Physics distinguishes between uniform linear motion (constant speed) and non-uniform (accelerating or decelerating).
- accelerationRate velocity changes
- velocityDirected rate of motion
- constant velocityUnchanging speed and direction
- displacementRemoval from usual location
