1)speedometre measure average speed
2)no because speed cant be negative
3)If A has both magnitude and direction them it is vector otherwise if only magnitude then scaler
4)acceleration remains constant
5)It does not have units hence no dimentional formula
6)energy stored is equal to amount of work done on the spring
7)If a reterding force is applied in opposite direction of motion example if we provide brake on moving car is negative work done...
