This content explains how to analyze forces on an inclined plane for a loaded box, differentiating between static and kinetic friction. It demonstrates calculations for the minimum force to prevent sliding down, the force to initiate...

Explore Newton's Laws of Motion with this physics problem. Determine if a block slides down a vertical wall when pushed by a horizontal force and calculate the wall's reaction force in unit-vector notation.

This video solves a physics problem calculating the speed a cyclist must maintain to achieve a specific power output while climbing an inclined path. It demonstrates the relationship between power, force, and velocity in a real-world...

This video provides a detailed solution to a Grade 11 physics problem involving the work done by a spring force on a box on an inclined plane. It explains how to calculate the work done by the spring as the box moves and the concept of...

This content explores the kinetic energy of a rolling object, comprising both rotational kinetic energy (1/2 I omega^2) and translational kinetic energy (1/2 M v_com^2). It emphasizes energy conservation in rolling, the crucial role of...

Discover how Newton’s First Law, or the Law of Inertia, explains everyday motion—why objects stop, when they keep going, and how friction plays a role. Learn with relatable examples like sliding books, parked cars, and ice skaters.

Forces are all around us and are the reason why objects accelerate (speed up, slow down or change direction)! Forces can either be balanced or unbalanced. When the forces are balanced, the net force is 0 and the object's motion will not...

Contrary to popular belief, temperature is not how hot or cold something is! This is a common misconception that many high school chemistry and science students have. In this video we will dive in to what temperature actually is and what...

Nolik is sad that he can't go sledding with Tom Thomas, and so he pours oil on the desk to make it super slippery. Unfortunately his whole Fixie family ends up getting stuck in the oil slick.
