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 physics problem demonstrates how to calculate the work done by the tension force as a cart is pulled up an incline using a rope and pulley system. It covers concepts of work, tension, and inclined planes.

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...

The use of 3-4-5 triangles in creating uniform right-angles and angles of incline in the ancient Pyramids of Egypt. Maths - Shape A Twig Math Film. Reinforce and extend the learning required by the curriculum. Twig’s math films show...

Discover how inclined planes, a basic but powerful type of simple machine, make it easier to move objects with less effort. Learn about the physics behind using ramps and slopes to harness gravity, and explore how different angles of...

Dr. Forrester discusses various types of simple machines, such as the lever, pulley, wedge, wheel and axle, screw, and inclined plane.

In this video, we tackle three multiple-choice questions related to friction. We start with a problem involving a block and a cube, discussing the forces at play and determining the force preventing acceleration. Next, we analyze a book...

This problem is about how the work done by gravity changes when an object slides up instead of down an incline.

Equations to memorize for the AP Physics 1 Exam.

Enjoy learning from Billy as he solves a problem using Work due to Friction equals Change in Mechanical Energy.

A rope is wrapped around a bicycle wheel with a rotational inertia of 0.68MR^2. The wheel is released from rest and allowed to descend without slipping as the rope unwinds from the wheel. In terms of g, determine the acceleration of the...

Billy does an example problem to review the work equation.

Review of all of the Dynamics topics covered in the AP Physics 1 curriculum.

A 0.453 kg toy car moving at 1.15 m/s is going up a semi-circular hill with a radius of 0.89 m. When the hill makes an angle of 32° with the horizontal, what is the magnitude of the force normal on the car?

Billy helps you review Conservation of Mechanical Energy, springs, inclines, and uniformly accelerated motion all in one example problem.

A book is resting on a board. One end of the board is slowly raised. The book starts to slide when the incline angle is 15°. What is the coefficient of static friction between the book and the incline?

You place a book on a 14° incline and then let go of the book. If the book takes 2.05 seconds to travel 0.78 meters, what is the coefficient of kinetic friction between the book and the incline?
