Relative Motion in Two Dimensions
... Reason: We know that the centripetal acceleration always points toward the center of the circle. Its magnitude is equal to the square of the speed divided by the radius of motion. That is, ac = v2/r. To measure the speed of an object moving in a circle, we measure the period, T, the time needed for ...

... Q2.5 According to Newton’s first law, the only way the velocity of an object can change is if there is a net force on the object. A car changes speed and/or direction when its tires experience a force exerted by the road. If the road is too slippery, the tires can no longer apply these forces and th ...
