Lab 08- Torque Lab

Objective: What causes rotational motion? The determining concept for rotational motion is torque. We will experiment with various situations to see how the concept of torque can be used to determine the rotational motion.

Theory: The principle behind balance can be explained by torque. Torque is the critical concept for rotational equilibrium. This can be explained by the balance experiment below:
