A horizontal line means the object is moving at a constant speed. The gradient of the line = the rate of change of speed. The steeper the line, the greater the increase in speed. The area under the ...

One must get the methods of measuring position and time working together if we are to obtain a reliable representation of motion. To that end we have developed a unique system composed of elements ...

Difference between Speed and Velocity: Speed and velocity are the most basic concepts from Physics. They form the part of your Physics textbook right from early classes when Physics is introduced as a ...
