Newton’s hypothesis was that some(?) Force was pulling the apples vertically downward. As long as the force is applied, the speed of the object continues to change and/or the direction of the object continues to change and/or the shape of the object continues to change. Velocity is the speed of a moving object in a certain direction.Ī Force is any action (a push or pull) that causes an object to change in speed, change in direction, or change in shape. Since the apples are falling in one direction, vertically, instead of speed, scientists call the motion velocity. Newton noted that apples always fall vertically (straight down). Much of Newton’s evidence was collected by observations,directly and indirectly, then with logical reasoning, he made informed decisions….
The name is derived from the Latin word “ gravis,” which means “ heavy,” “ having weight,” while the Law of Gravitation is defined as “ That mutual action between masses of matter by virtue of which every such mass tends toward every other with a force varying directly as the product of the masses, and inversely as the square of their distances apart.”Ī way of gaining knowledge by means of direct and indirect observation or experience.
We are such stuff As dreams are made on, and our little life Is rounded with a sleep. These our actors, As I foretold you, were all spirits and Are melted into air, into thin air And, like the baseless fabric of this vision, The cloud-capp’d towers, the gorgeous palaces, The solemn temples, the great globe itself, Yea, all which it inherit, shall dissolve, And, like this insubstantial pageant faded, Leave not a rack behind. You do look, my son, in a moved sort, As if you were dismay’d.
