Directions: Read the following text to get a basic understanding of the kinematic equations and then answer the questions that follow. The kinematic equations are four equations that can predict unknown information about an object's motion if three of its four variables are known. The equations can be used when an object has either a constant velocity (acceleration = 0 m/s 2 ) or a constant acceleration. The equations of kinematics cannot be used in scenarios where the acceleration is changing. For example, the equations can be used to predict the displacement of a car over a certain time interval if its initial velocity and acceleration are known, but the equations will not be applicable if the car changed its acceleration during the time interval.
