47. Newtons First Law states that objects maintain a constant speed velocity unless acted on by a net
Lab # 7: Ballistic Pendulum
In this experiment, the speed of a projectile will be measured in two different ways;
through the use of conservation laws and using kinematic equations as in projectile motion.
