PHYS 102: General Physics 1

Analyze the physics of a falling squirrel, calculating its velocity upon hitting the ground and the deceleration due to limb bending.

Learn how to calculate the kinetic energy of a Saturn 5 rocket with an Apollo spacecraft attached using physics principles and formulas. Understand the importance of unit conversion and the work-energy theorem as you plug values into the KE = 1/2 mv² formula. Discover that the kinetic energy for this rocket and spacecraft combo is an astonishing 1.82 x 10¹³ Joules.

Learn how to compute the displacement of a ball rolling off a table using calculus. Through the integration of velocity over a specific time interval, determine the ball's position. Uncover the mathematics behind real-world motion scenarios.

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.

Explore the physics of a tennis ball hitting a wall and its momentum changes. Learn about the original momentum, changes, and the concept of reference objects in this engaging video.

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!
