1. Understanding physical principles is often very useful in everyday life. For example, a skater develops an intuitive understanding of angular momentum in order to master making turns, and virtually all of us as car drivers come to understand the principles of inertia, velocity, and linear momentum. Can you name at least 2 everyday situations where physics plays a role and what physical principles are involved?

2. What is the difference between a vector and scalar distance? Name at least 2 examples from everyday life where each is used.

3. What is the difference between speed and velocity? between velocity and acceleration? Name at least one example from everyday life where each of these concepts (speed, velocity, acceleration) is important (3 total).
