    				| 1. | Give two point of difference between speed acceleration | 
| Answer» Speed is the rate of change of distance(basically how much distance(m) has been covered in a particular time(s)). Velocity is the rate of change of displacement( change of distance in a particular direction with respect to time) , and acceleration is the rate of change of velocity per UNIT of time.(AMOUNT of increase or decrease in velocity). Also, speed is a scalar QUANTITY but velocity and acceleration are VECTOR quantities. | |
