Discover the incredible tale of David Purley's survival in a high-speed car crash! In this video, we calculate the magnitude of the acceleration he experienced during the rapid deceleration from 173 km/h to zero. Learn how to express it in units of gravity and explore the limits of human endurance.
Projectile Range and Optimal Launch Angles Explained
Want To Learn More? To watch the entire video and ALL of the videos in the series:
Join us in this enlightening video as we explore the fascinating world of projectiles and their optimal launch angles. We dive into the physics behind how a fixed initial speed affects the range of a projectile and why, for most angles, there are two choices that yield the same range. Delve into factors that affect an archer's ability to hit a target, including wind, and learn why a smaller angle, closer to the horizontal, is often preferable. Discover when and why a larger angle may be necessar
