PHYS 101: The Physical World

Unlock the secrets of battery performance in this video! We calculate the terminal voltage for a battery with internal resistance, connected in series with resistors of different values. Explore the effects of resistance on voltage in electrical circuits.

Unpack the concept of normal force on a sports car and its driver atop a hill. Utilize Newton's second law to calculate these forces based on speed and hill curvature. Discover the speed at which the driver feels weightless in the car.

Explore the fascinating comparison between the acceleration of a motorcycle going from 80 km/h to 90 km/h and a bicycle accelerating from rest to 10 km/h in the same time frame.

Discover the physics behind violin string tension and the angle-dependent force required when pushing it against the neck. Explore how the angle affects the force needed.

Explore the intriguing dynamics of a spring-mass system, set in motion by a hammer's impact. Learn about period, frequency, amplitude, acceleration, position over time, and the total energy of this unique scenario.

Explore the dynamics of a bead under constant force. Understand its acceleration, velocity over time, and how to calculate its kinetic energy. Witness the interplay of motion equations and real-world applications in a simple system.
