## Acceleration and Freefall

Summary

The content delves into the concepts of acceleration, gravity, and freefall, focusing on their implications in physics and their application in solving kinematic problems. It emphasizes the importance of understanding uniform acceleration, the fundamental kinematic equations, and the special case of freefall under Earth's gravitational pull.

- Acceleration in physics refers to any change in speed, including speeding up and slowing down, with a focus on uniform acceleration where the rate of acceleration remains constant.
- The fundamental equation for constant acceleration is introduced, alongside a discussion on units of measurement for speed and acceleration, and the concept of meters per second squared.
- Graphical representations of acceleration, including speed versus time and distance versus time graphs, are explained to illustrate constant acceleration and deceleration.
- Four crucial kinematic equations are presented as essential tools for solving physics problems involving motion, with specific examples provided to demonstrate their application.
- The concept of freefall is explored, highlighting Galileo's discovery that the acceleration due to gravity is constant and does not depend on an object's mass, with practical problems illustrating its application.
