PHYS 1112: Physics I: Mechanics & Heat

Join us in a lunar leap! We estimate how gravity affects jumping distance on the Moon compared to Earth, with the same takeoff speed and angle. Explore the moon's reduced gravity and its impact on human capabilities.

Discover how to calculate rope tension with an object hanging in the center. Understand the relationship between the sag, the weight of the object, and the tension. Convert the result into kilonewtons for easy reference.

Dive into the physics of cliff jumping as we analyze the splashdown speeds of two adventurous youngsters. Explore the factors that determine their speeds and choose the best explanation among the options provided.

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

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.

Delve into Newton's third law of motion and explore how the choice of the 'system of interest' influences whether force pairs cancel each other out.
