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.

In this educational video, we dive into the concept of volume and its units. We explore the correct units for measuring volume and discuss the common misconception that a cylinder's volume is given by ?r^3h. Join us for a comprehensive explanation of the fundamentals of volume measurement and understand why the given formula doesn't hold.

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

Discover the gravitational forces at play in a triangle of masses in this video. We calculate the net force on each mass and explore how changing the side length impacts these forces. Join us for a gravitational journey through physics.

Learn how to determine the hot resistance and current in the electrical system of older cars with a 6.00-V voltage supply.

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.
