The Florida Supreme Court addressed whether we should now replace the doctrine of joint and several liability with one in which the liability of codefendants to the plaintiff is apportioned according to each defendants respective fault. Analyzing the issue, the Court reasoned that [t]here is nothing inherently fair about a defendant who is 10% at fault paying 100% of the loss, and there is no social policy that should compel defendants to pay more than their fair share of the loss. Ultimately, the Court held that [i]n view of the public policy considerations bearing on the issue, this Court believes that the viability of the doctrine is a matter which should best be decided by the legislature. Thus our experience tells us that a baseball has more mass than a The Concept of Force and Newton's First Law. As a result, the momentum of the moving ball will be transferred to the stationary ball, causing it to move in the direction of the force. Momentum is a property of moving objects that describes how difficult it is to stop them.
