PHY 143: Sex Assault Harassment/Awareness & Avoid

Understand how to determine the coefficient of kinetic friction using a wooden block and a spring. Employing the law of conservation of energy, we use the spring's compression and stretch measurements. Through energy equations and Newton's second law, we deduce that ? equals 0.4.

Join us to explore the science of hand-warming through friction in this video. We calculate the temperature increase as a woman rubs her hands together, converting work into thermal energy. Dive into the physics of heat generation and discover how friction can keep you warm.

Learn how to determine the hot resistance and current in the electrical system of older cars with a 6.00-V voltage supply.

Explore the physics behind a water-skier accelerating from an initial speed to a faster one. Learn how to calculate the work done using the change in kinetic energy. Understand the principle of energy conservation through real-world examples.

Uncover the fascinating science behind peephole lenses, including the principles of light refraction and observer positioning that allow for an extensive field of vision through a hotel room door.

Explore the intriguing physics of a sandal dropped from a moving ship and learn how to calculate its velocity relative to the ship and a stationary observer on shore.
