PHYS 12728: Concepts of Physics

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.

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.

Exploring the behavior of oil and water in a U-shaped tube when a barrier is removed. Understand the impact of differing densities on fluid heights. Witness equilibrium scenarios effects of equal densities and the displacement dynamics of lighter liquids.

Estimate a car's initial speed from skid marks using physics principles. Apply Newton's Second Law and equations of motion to deduce the initial velocity. Understand the role of frictional force in car deceleration during accidents.

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 key reasons why measurement standards rooted in laboratory procedures offer advantages over standards based on specific objects, like the international prototype kilogram. Dive into the world of metrology and standardization in this informative video.
