Velocity is a vector physicalquantity expressing character displacement of an object per unit of time. Its dimensions are [L] / [T]. This unit in the International System is m / s. The velocity is considered the direction oftravel and the module, which is called speed or quickness. Just as speed is the rhythm or rate of change of position per unit time, acceleration is the rate of change of velocity per unit of time.[Robert Resnick and Jearl Walker, Fundamentals of Physics, Wiley; 7 Sub edition (June 16, 2004)].
Make a scale model crane. The problem is to make a crane that has the same featuresas the original cranes and may still be loaded. When you lift up the object that we will get in a lift height needed and when we drop the problem will calculate the exact time to get the speed usingthe formula distance time
Is it true that more weight, gives more speed?
If we use the gravity and momentum, using the weight of an object. Then we will check the researchto see if they tell the truth that more weight will fall faster.

Aristotle studied physical phenomena without actually conceptualize a notionof speed. Explanations of Aristotle (who subsequently prove incorrect) only phenomena described in words, without using mathematics as a tool.
It was Galileo Galilei who, studying the motion of bodieson an inclined plane reached a speed concept. What he did was to divide the distance in units of time. That is, a fixed pattern of one unit of time, eg 1 second, and from this the distance linked...
