5 Questions
What are Newton's three laws of motion?
- A body remains at rest, or in motion at a constant speed in a straight line, unless acted upon by a force. 2) When a body is acted upon by a net force, the body's acceleration multiplied by its mass is equal to the net force. 3) If two bodies exert forces on each other, these forces have the same magnitude but opposite directions.
When were Newton's three laws of motion first stated and in which publication?
Isaac Newton first stated the three laws of motion in his Philosophiæ Naturalis Principia Mathematica (Mathematical Principles of Natural Philosophy), originally published in 1687.
How did Newton use his laws of motion and what did they lay the foundation for?
Newton used his laws of motion to investigate and explain the motion of many physical objects and systems, which laid the foundation for classical mechanics.
What limitations to Newton's laws have been discovered?
New theories are necessary when objects move at very high speeds (special relativity), are very massive (general relativity), or are very small (quantum mechanics).
In what terms are Newton's laws often stated?
Newton's laws are often stated in terms of point or particle masses, that is, bodies whose volume is negligible.
