Newton's Second Law of Motion
This section introduces Newton's Second Law of Motion - The acceleration of an object is directly proportional to the net force acting on the object, and inversely proportional to the mass of the object. 2018-03-21, 1127👍, 2💬
Newton's Third Law of Motion
This section introduces Newton's Third Law of Motion - If a force is exerted by one object to another object, another force is simultaneously exerted by the second object to the first object with equal strength and opposite direction. 2017-11-28, 1581👍, 1💬
Meter Based on Earth's Meridian
This section introduces an old definition of 'meter' which uses the Paris meridian line. A 'meter' is about one ten-millionth of the length of a quadrant of the Paris meridian. 2017-10-08, 2114👍, 2💬
💬 2017-10-08 Herong: Peter, what's the difference between inaccurate and miscalculated?
💬 2017-10-07 Peter: This explanation is incorrect. You are inferring from speed of light definition and assuming a broader sense of “correct” and wo...
