Acceleration - History, Linear Acceleration, Circular Acceleration, Force And Acceleration
object time units motion
The term acceleration, used in physics, is a vector quantity. This means that acceleration contains both a number (its magnitude) and a specific direction. An object is said to be accelerating if its rate of change of velocity is increasing or decreasing over a period of time and/or if its direction of motion is changing. The units for acceleration include a distance unit and two time units. Examples are m/s2 and mi/hr/s. Sir Isaac Newton (1642-1727) in his second law of motion defined acceleration as the ratio of an unbalanced force acting on an object to the mass of the object.

The study of motion by Galileo Galilei (1564-1642) in the late sixteenth and early seventeenth centuries and by Sir Isaac Newton in the mid-seventeenth century was one of the major cornerstones of modern Western experimental science. Over a period of 20 years, Galileo observed the motions of objects rolling down various inclines and attempted to time these events. He discovered that the distance a…
An object that is moving in a straight line is accelerating if its velocity (sometimes incorrectly referred to as speed) is increasing or decreasing during a given period of time. Acceleration (a) can be either positive or negative depending on whether the velocity is increasing (+a) or decreasing (-a). An automobile's motion can help explain linear acceleration. The speedometer measures th…
In circular motion, the velocity may remain constant but the direction of motion will change. If our automobile is going down the road at a constant 60 MPH and it goes around a curve in the road, the auto undergoes acceleration because its direction is constantly changing while it is in the curve. Roller coasters and other amusement park rides produce rapid changes in acceleration (sometimes calle…
Before the time of Sir Isaac Newton, the concept of force was unknown. Newton's second law was a simple equation and an insight that significantly affected physics in the seventeenth century as well as today. In the second law, given any object of mass (m), the acceleration (a) given to that object is directly proportional to the net force (F) acting on the object and inversely proportional…
