Explore the concept of acceleration in this physics lecture, focusing on its definition and the interpretation of acceleration graphs. Delve into real-world examples, including animal movements, car acceleration, and objects on inclined planes. Learn to analyze motion diagrams, determine the sign of acceleration, and interpret position, velocity, and acceleration graphs for various scenarios. Gain a solid foundation for understanding constant-acceleration motion equations, which will be introduced in the subsequent lecture.

THE SIGN OF ACCELERATION
The motion diagram shows a particle that is slowing down. The sign of the position and the sign of the velocity are
For each of the four motion diagrams below, determine whether the acceleration is positive or negative.
