Roller-coaster, Belmont Park, Mission Beach, San Diego, CA, USA

According to the First Law of Motion published by Sir Isaac Newton, objects will move in a straight line unless acted on by an external force. Also known as Linear Motion. There are two cases:

a) the object moves in a straight line at a constant velocity called Uniform Linear Motion.
b) the object speeds up or slows down called Non-Uniform Linear Motion.
