WebNewton’s first law of motion states that there must be a cause—which is a net external force—for there to be any change in velocity, either a change in magnitude or direction. An object sliding across a table or floor slows down due to the net force of friction acting on the object. WebAn object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force. Balanced Forces But what exactly is meant by the phrase unbalanced force? What is an unbalanced force? In pursuit of an answer, we will first consider a physics book at rest on a tabletop.

WebThe state of motion of an object is defined by its velocity - the speed with a direction. Thus, inertia could be redefined as follows: Inertia: tendency of an object to resist changes in its velocity. An object at rest has zero velocity - and (in the absence of an unbalanced force) will remain with a zero velocity. WebAn object at rest stays at rest and an object in motion stays in motion at a constant speed and direction unless acted upon by an unbalanced force. By the time Newton came along, the prevailing theory of motion—formulated by Aristotle—was nearly two thousand years old. http://physics.bu.edu/~duffy/ns540_fall10_notes01/EP_ch02_2dash1to2dash4.pdf ipos end of life
