Physics Aviary
Physics Aviary: Atwood Machine Lab
This lab was designed to have students practice the Atwood lab prior to doing it for real. Students can adjust the masses and the planet and then collect position vs. time data and velocity vs. time data.

Physics Aviary: Practice Problems: Forces on Incline Problem Medium
Students must find out force normal on an object on an incline at the angle at which the object is first about to slip.
Physics Classroom
The Physics Classroom: Vectors: Forces in Two Dimensions: Addition of Forces
In this tutorial, examine the effect of forces acting at angles to the horizontal, such that the force has an influence in two dimensions- horizontally and vertically.

Khan Academy
Khan Academy: Inelastic Collision Review
Review the key concepts and skills for inelastic collisions. Understand how to determine if a collision is elastic or inelastic.
Khan Academy
Khan Academy: Conservation of Angular Momentum Review
Review how angular momentum is conserved if there is no external torque applied to a system. Specific scenarios are highlighted: system changing it rotational inertia, orbiting bodies, and rotational collisions.
