In the video of the scooter ride, we saw that the speed of the scooter was changing according to the situation on the road.
Is it possible in real life to maintain just one same speed, not less or more, throughout the journey?
It might not be possible to maintain the same speed throught the journey. But if you can still imagine a journey like this where the rider just maintains one speed, kilometer after kilometer, it means that for every kilometer it takes exactly the same time to cover it.
This unchanging speed is known as constant speed.
Train in the given picture is covering 15 km in 15 min throughout the journey, so it can be said that the train is in uniform motion or moving with constant speed.
Think of other instances where you can witness objects moving at constant speed?
For example, minute hand and second hand of a clock moves at a constant speed. The speed of the tip of the minute hand or second hand of a clock are same.
Can you measure the speed of the minute hand of your wrist watch?
