Physics Aviary: Practice Problems: Time to Traverse the Table
Students must find the time that it takes for the block to move across the table. This will involve an acceleration and a period of travel at a constant speed.
Physics Aviary
Physics Aviary: Practice Problems: Speed of Horizontal Projectile
Students must determine the horizontal speed of a projectile based on the distance that it travels and other given information. Students must find the time of flight and put it in milliseconds. Finally, students must find the final...

Physics Aviary: Graphing Motion Problem Level 2
Find the distance traveled by an object just by looking at the velocity vs. time graph.
Physics Aviary
Physics Aviary: Accelerating Electrons Lab
This lab is designed to have students investigate the factors that affect the speed of an electron and the time it takes an electron to travel the distance between two charged plates.
Physics Aviary
Physics Aviary: Projectile Lab
This lab is designed to have students find the relationships that affect the horizontal distance travelled by a projectile. Students will be able to modify the starting height, initial speed and angle at which the projectile is fired....
Physics Aviary
Physics Aviary: Graphing Motion Problem Level 1 Part 3
Find the distance traveled by an object by looking at the velocity vs. time graph. All velocities are constant.
