Isaac Newton developed the principles of modern physics through his studies on mathematics, optics and motion. His book "Philosophiae Naturalis Principia Mathematica," or "Mathematical Principles of Natural Philosophy," is often cited as the most influential document on physics. Isaac Newton is most famous for his law of gravitation.
Isaac Newton played an integral role in the scientific revolution that occurred during the 17th century. He studied optics heavily and delivered annual lectures as a professor. A major component in his optics study was the reflecting telescope that he invented in 1668. His telescope was the first achievement that gained him fame and acclaim. The telescope also allowed Newton to study outer space and prove his theory of light and color.
Isaac Newton's theories on gravity explain motion in the universe. He started studying why planets orbit each other and came up with three basic laws of motion. The first states that an object does not move unless force is applied to it. The second states that force is equal to mass times acceleration, and a change in motion is proportional to the force applied. The third states that there is an opposite and equal reaction for every action. These laws provided many answers to scientific questions, including how the Earth's tides are created by gravitational forces from the moon and sun, and why the moon orbits the Earth.Learn More
According to Concord Consortium, pith-ball, gold-leaf, and needle electroscopes measure electric charges using Coulomb electrostatic forces. Pith-ball electroscopes use attraction as a measure of charge, while gold-leaf and needle electroscopes use repulsion. These early instruments helped scientist understand and measure electric charges and polarity. Today they serve primarily as demonstration instruments.Full Answer >
Some examples of luminous objects are a burning candle, a light bulb, the sun and other stars, fluorescent materials and tube lights, among other things. Any object is considered luminous if it emits its own light, either through stored energy or energy supplied to the object, which contrasts with non-luminous objects such as the moon, wood, plastics and metals; these objects merely reflect light instead of providing their own.Full Answer >
An object is said to have uniform velocity if the direction of motion and the rate at which the object changes its position is constant. In other words, an object with uniform velocity continues to cover the same amount of distance over the same time interval without changing its direction.Full Answer >
The work of Sir Isaac Newton revolutionized science and laid the foundations of modern mathematics and physics. Among his accomplishments are the formulation of the laws of motion and gravitation, the development of calculus and the invention of the first reflecting telescope.Full Answer >
