The lecture explains the concept of free fall, where only gravity acts on a body, causing it to accelerate towards Earth. It discusses displacement and velocity changes over time, illustrating how velocity increases as a body falls. The constant acceleration of 9.8 m/s², known as acceleration due to gravity, is highlighted. The lecture also addresses tricky questions about acceleration at peak points when a body is thrown upwards, emphasizing that acceleration remains constant at 9.8 m/s². Finally, it clarifies that the direction of acceleration due to gravity is always downward.
