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, 733👍, 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, 698👍, 1💬
Reciprocity of Time Dilation
This section introduces the reciprocity of time dilation. Elapsed time of a moving clock is slower when measured by a stationary observer; and elapsed time of a stationary clock is slower when measured by a moving observer. 2017-12-09, 590👍, 2💬
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, 540👍, 2💬
Meter Based on Seconds Pendulum
This section introduces an old definition of 'meter' which uses a seconds pendulum. A 'meter' is the length of a seconds pendulum, which swings a full cycle in 2 seconds in small angles. 2017-06-14, 451👍, 1💬
