Before I start my investigation I am going to clarify the difference between velocity and speed as many people get this wrong. ... Speed is the distance traveled in unit time, without knowing the direction. In my investigation I am going to drop cake cups from several heights to calculate the constant speed that the cups will travel downwards. ... As I do this I will add more cups to the original first cup to find out that if you double the weight it also doubles the speed. ... Results Table (time in seconds) Cups Time in (s) Time in (s) time in (s) average (s) m/s velocity v...

Producing more down force gives a car more control and stability but sacrifices speed. ... Interference Drag: A fundamental fact of aerodynamic life is that drag increases with the square of the speed. Meaning when you double the speed, you quadruple the drag. ... Aerodynamic down force - measured in pounds - is a square function of speed. Its impact increases at higher speeds. ...

The kinetic energy [K.E = ½ mv ] depends on the mass of the object and its speed. ... The falling motion of the bob is accompanied by an increase in speed. As the bob loses height and PE, it gains speed and KE. As the speed is increased, and the bob moves from Q to X, the total energy exhibited at X will be at its maximum. Alternatively if the speed is decreased, and the bob moves from X to Q, the total kinetic energy exhibited will be zero. ...
