IGCSE Physics PowerPoint Presentation | Speed , Velocity and Acceleration
1. Speed as distance covered per unit time; units in meters per second or kilometers per hour; average speed calculations based on uniform motion.
2. Velocity as a vector quantity with magnitude and direction; directional impact on measurements; examples illustrating motion in different directions.
3. Acceleration as the rate of velocity change over time; described as positive, negative (deceleration), or constant; practical examples of varying acceleration scenarios.
4. Motion analysis through velocity-time graphs; gradient for acceleration determination; area under the graph representing distance traveled; scenarios of steady motion, acceleration, and deceleration.
5. Free fall under gravitational acceleration; air resistance influencing objects differently based on shape and surface area; terminal velocity achieved with balanced forces.
6. Interaction of drag and gravity; larger objects experience greater drag; terminal velocity reached when upward drag equals downward gravitational force.
