Physics Aviary
Physics Aviary: Practice Problems: Stopping Distance Problem
Students must calculate coefficient of friction based on the distance required to stop a car moving along a roadway.
Physics Aviary
Physics Aviary: Practice Problems: Motion on Incline Level 2
Students must calculate the distance an object will move up an incline using Newton's Laws. Mass, angle, gravitational field, coefficient of friction and initial speed will be generated randomly.
Physics Aviary
Physics Aviary: Practice Problems: Motion on Incline Level 3
Students must calculate the speed of a block when it returns to its original location on an incline using Newton's Laws. Mass, angle, gravitational field, coefficient of friction and initial speed will be generated randomly.

Physics Aviary: Practice Problems: Acceleration on Incline Problem Medium
Students must calculate the acceleration of an object down an incline when there is friction present. Mass, angle and coefficient of friction will be generated randomly.
