PHYS 152: General Physics

Dive into the world of buoyancy and density in this video! We explore how an object's weight changes when immersed in water and oil. Join us to calculate the density of the object and the oil, unraveling the principles of fluid dynamics and buoyant forces.

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!

Discover how energy conservation principles determine the velocity of a bouncing ball. Relate the ball's height and its potential and kinetic energies. Understand the velocity change upon impact and rebound.

Join us in exploring the concept of significant figures in numerical values. Learn to identify and count significant figures in various numbers, from whole numbers to decimals. Understand the precision and accuracy of your measurements through this engaging video.

Discover how to optimize the launch tube acceleration to achieve the maximum height and earn the most points in your laboratory experiment.

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.
