Previously you studied how physics has a special language in the form of variables. These variables form equations that are used to answer questions about the properties, characteristics, and behavior of motion. Below is a chart that will help you explore some of these equations. As you explore these equations, answer the following questions in your notes.

1. How are the displacement equation and the time equation similar?

   Interactive popup. Assistance may be required.

   Check Your Answer

   The equations both use the delta sign and include the symbols for final (f) and initial (i).

2. How are the velocity and acceleration equation related?

   Interactive popup. Assistance may be required.

   Check Your Answer

   You have to solve for velocity before solving for acceleration.

3. How are the variables of velocity, displacement, acceleration, and time related in the kinematics equations?

   Interactive popup. Assistance may be required.

   Check Your Answer

   Each of the variables plays a role in other equations.

4. How might understanding the relationships between variables and equations help you when trying to solve physics problems?
