Distinguish between speed and velocity.
Solution 7RQ Step 1 : We need to distinguish between speed and velocity speed velocity distance travelled by an object distance travelled by an object per unit volume in a particular direction scalar quantity vector quantity it is calculated using distance travelled it is calculated using displacement and time and time taken taken it is denoted by km / hr , mph , feet it is usually written in m/s formula velocity = distance travelled formula time taken displacement velocity = time taken
