Athlete's Power: Watts in a 5m Rope Climb
Want To Learn More? To watch the entire video and ALL of the videos in the series:
Explore the physics behind an athlete's rope climb. Understand the relationship between power, force, and time, and how to calculate the minimum power output an athlete exerts. Witness the interplay of physics principles in evaluating athletic prowess.
hysics of a Coin Drop in an Ascending Elevator
Want To Learn More? To watch the entire video and ALL of the videos in the series:
In an elevator ascending, an occupant drops a coin, which accelerates at a different rate than expected. This reveals the elevator's own acceleration towards the Earth. By analyzing forces and tensions, we determine the cable's tension to be 16000 N.
River Rescue: Angle for Direct Approach to Child
Want To Learn More? To watch the entire video and ALL of the videos in the series:
Join us for a dramatic river rescue mission! In this video, we solve the problem of how a rescue team can reach a child in danger of drowning in a fast-flowing river. We calculate the angle from the shore for their pilot to approach the child directly, considering the river's current and the boat's speed. Explore the principles of vector addition and save lives!
Spacecraft Speed Change in 1 Week with 0.09-N Thrust
Want To Learn More? To watch the entire video and ALL of the videos in the series:
Discover the impact of a 0.09-N thrust engine on a 480 kg spacecraft's speed during 1 week of maximum power operation. Uncover the assumptions involved in this space physics scenario.
Physics Behind Normal Force: Car & Driver on a Hill's Rounded Top at S
Want To Learn More? To watch the entire video and ALL of the videos in the series:
Unpack the concept of normal force on a sports car and its driver atop a hill. Utilize Newton's second law to calculate these forces based on speed and hill curvature. Discover the speed at which the driver feels weightless in the car.
