Q.

1.Assertion:The position time graph of a body moving uniformly in a straight line parallel to position axis. Reason:The position time graph in a uniform motion gives the velocity of an object.

2.Assertion:Average speed is equal to total distance travelled divided by total time taken. Reason:The average speed of an object may be equal to arithmetic mean of individual speed. MY DOUPT: AVERAGE SPEED = \(\frac {(V_1+V_2)}2 \), FOR FIRST HALF OF TIME , the velocity is \(V_1\) and the NEXT HALF OF TIME, the velocity is \(V_2\).Form this situiation average speed may be equal to arithmetic mean of individual speed.
