Gravity and drag. Gravity accelerates the object and drag (caused by friction) slows it down. When the full effect of these two forces have been applied to an object, that object is said to have...
Well I tell u like this velocity,v equalls accelaration * time. When v is 0 thenaccelaration,a and time becomes zero. When a is zero then force is zero then workis zero then Energy is zero then...
