Newton’s Second Law also says that the greater the mass of the object being accelerated, the greater the amount of force needed to accelerate the object. You are increasing the speed of the bicycle by applying force to the pedals. When you push on the pedals, your bicycle accelerates. Your leg muscles pushing pushing on the pedals of your bicycle is the force. Riding your bicycle is a good example of this law of motion at work. Newton’s Second Law of Motion says that acceleration (gaining speed) happens when a force acts on a mass (object). Consequently, the principles are referred to today by his name – Newton’s First, Second and Third Law of Motion. Newton is best known for three important principles of physics that describe how things move. He lived just before the American Revolution. This was around the time of the early colonization of North America. Sir Isaac Newton was an English scientist.
