![]() ![]() Given the angle the rope is deflected from the vertical, find the acceleration of the truck. A ball hangs from a rope that is attached to the ceiling of a truck. This video covers 2 Newton's 2nd Law Problems. Video B2.1: Two Newton's 2nd Law Example Problems : Ball Hanging From the Ceiling of a Truck and Crate in a Truck. It looks at an object on an inclined plane where friction is present. Video B2: Inclined Planes (Continued from Video B1): This video is continued from video B1. Video B1.2: The Force of Kinetic Friction This video explains why a string or rope of negligible mass will usually have the same tension throughout it. Video B1.1: Basics on the Force of Tension. This video shows the steps to solving a Newton's second law problem with particular attention given to an object moving on an inclined plane. Video B1: Solving Newton's Second Law Problems. Some basics of the relationship between velocity and acceleration vectors. Video A9: Vector Basics (part 2) Vector Basics (part 2). Just the basics of vector notation including an explanation of unit vectors. AP PHYSICS C HOW TOAll velocities are relative, this video describes how to find the velocity of one object relative to another object using vectors. It is a good method for quickly checking your answers on kinematics tests. This video uses the idea of average velocity to quickly solve some types of kinematics problems. ![]() Video A5: A Quick and Intuitive Way to Solve Some Projectile Motion Problems. AP PHYSICS C FREEVideo A4: A Quick and Intuitive Way to Solve Some Free Fall Problems. Video A3: A Quick and Intuitive Way to Solve Some Kinematics Problems. Note: integral calculus is used for these derivations. Video A2.1: Deriving the Kinematics Equations for Straight-Line Uniform Acceleration Using Calculus. Video A2: Deriving the Kinematics Equations for Straight-Line Uniform Acceleration Using the v vs. Quickly explains what is meant by each of these terms including average and instantaneous velocity.
