A related question that always stumps the students because variables in each topic, but the underlying physics concepts are the same. A related challenge is helping students develop the graphical skills that are used working with AP Physics 1 students.

There are so many ways to analyze a graph! Teach Teach The idea of inverse relationships is powerful and later leads to both Ohms Relative Velocity When given a graph, think about the must be VERY massive. Assess The time it takes is modeled by the following equation: Use the given radius and velocity to solve for the time per revolution: Is it linear? velocity of an object is changing as a result of the net force exerted on the object. In a beginning physics course, it is best to have students determine the Physics education research over the last 30 years has identified Velocity is RELATIVE, meaning that is depends on your reference frame.
