Physics questions

  1. What is the difference between “torque” and “force”? Describe/illustrate the concept of torque using an example. 2. Describe the nature of the torque-velocity relationship. In other words, what happens as contraction velocity increases? What type of contraction is occurring when peak torque is being produced? 3. Physiologically, what might determine the nature of the torque-velocity relationship? In other words, why does contraction velocity affect the amount of torque that can be produced by a skeletal muscle? Consider the cross-bridge cycle as you think about this question.
