Linear Motion (Translational Motion)
Can be described as movement in a particular direction. An example of this type of motion is a sprinter running down the track towards the finish line. In this case the sprinter is using force generated by his or her muscles which results in motion in a straight line.
This type of motion refers to movement around an axis. In rotational motion the force does not act upon the centre of mass. It is rather off centred which results in the rotation of an object. If a soccer ball is kicked through the centre of mass it will go in a straight line. If it is kicked more to the side of the ball it will rotate and spin.
