PHYS 1100: Physics 1

Explore the relative strengths of two fundamental forces, the electromagnetic force and the gravitational force, in this enlightening physics tutorial. Learn about Coulomb's law and Newton's law of gravitation, and uncover the significant difference in their constants that makes the electromagnetic force much more powerful than gravity.

Discover the physics behind the angle formed by loosely hanging hand straps on a streetcar negotiating a curved turn.

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.

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.

Discover the math behind car spring oscillations when driving over bumps. Understand how a car's weight and driver affect the spring constant and resulting frequency. Grasp the interplay of forces and how they dictate harmonic motion.
