Force and mass determine acceleration.
... To get more acceleration, he must apply more force. The same idea holds for a ball you whirl on a string. You have to pull harder on the string when you whirl the ball faster, because it takes more centripetal force to keep the ball moving at the greater speed. You can apply the formula for Newton’s ...

Motion in one and two dimensions
... All motions are relative.The motion (velocity) of an object depends on which frame of reference is used to measure it. We say the measured velocity is relative to the chosen frame of reference. Usually the ground is the preferred choice as the reference frame and very often it is not specifically me ...
