Is time goes faster for short things?

    Am i right?
    Short things can be faster!
    theyre moves, to do things are short . and they can finish they jobs more fast for example falling of 2 meter and 5 meter tree . Both fall on same time but 5 meter tree must and in did fall by higher speed than 2 meter tree
    Or
    Openning a big door or small door or walking of big animal and small ones!
    Yes we say time is a taking time to move clock pointer and its static but what if we was wrong? and speed is static and time is dinamic?
    Speed=lenght/time
    Ant can lift huge burden and walking so fast relat to elephent
    Or feel pain faster or think faster and fell faster and happy faster and its life is ended faster!

    You need to be careful to compare like with like and to establish what variables you are dealing with. It is true that things don't just 'scale up and down'. Material strength is relevant when you try to scale things up in size, so an Elephant needs short stumpy legs but a spider can have long spindly ones. That allows high (scale) speeds for small animals. But there is an issue with electric forces vs gravitational forces. We are not much affected by the inter-molecular forces (viscosity) of air or even water but insects find air to be like treacle and an air/water interface is the equivalent of walking on a water bed (they can't easily break through).
    It may appear that a mouse can run fast but, in a straight line, an elephant will win.
    Newton's Laws apply to everything- if you apply them right! :smile:

    I think the issue is not time (which, despite relativity) is pretty much universal in our everyday world.
