I have not as yet been able to discover the reason for these properties of gravity from phenomena, and I do not feign hypotheses. For whatever is not deduced from the phenomena must be called a hypothesis; and hypotheses, whether metaphysical or physical, or based on occult qualities, or mechanical, have no place in experimental philosophy. In this...
The First Law of Motion, commonly called the “Principle of Inertia,” was first realized by Galileo. (Newton did not acknowledge Galileo’s contribution.) Newton was particularly concerned with how to phrase the First Law in Latin, but after many rewrites Newton choose the following expression for the First Law (in English translation): Law 1: Every ...
Newton began his analysis of the cause of motion by introducing the quantity of motion:
The quantity of motion is the measure of the same, arising from the velocity and quantity of matter conjointly. The motion of the whole is the sum of the motion of all its parts; and therefore in a body double in quantity, with equal velocity, the motion is double, with twice the velocity, it is quadruple.5 Our modern term for quantity of motion is...
Motion. • What is Motion in Physics? In physics, the motion is the change in position of an object with respect to its surroundings in a given interval of time. The motion of an object with some mass can be described in terms of the following: Distance. Displacement. Speed. Velocity. Time. Acceleration. Main types of motion.
Application of Newton’s laws: Prescription. Step 1: Divide a composite system into constituent systems each of which can be treated as a point mass. Step 2: Draw free body force diagrams for each point mass. Step 3: Introduce a coordinate system, the inertial frame, and write the equations of motion.
velocity = speed + direction of motion Things that have both a magnitude and a direction are called vectors. More on vectors in Ch.3. For 1D motion (motion along a straight line, like on an air track), we can represent the direction of motion with a +/– sign. + = going right .
