Vertical Marble Launcher

Durable apparatus to study velocity acceleration and projectile motion.

Vertical marble launcher.

The solid heavy base provides an easy to use and reliable setup. Attach one photogate to the marble launcher so that the marble breaks the light beam as it comes out of the barrel. For this experiment you will use angles from 0 to 80 degrees. Arrange the desk in a way such that the direction of launch will be clear for at least 4 meters.

Launch steel balls at angles between 0 and 70 degrees and over distances up to 2 5 m. B the horizontal distance. If additionally α 90 then it s the case of free fall. B how far from the table will it hit the floor.

The vertical velocity component vy is equal to v sin α. A marble with a speed of 2 0 m s rolls off the edge of a table 1 8 m high a how long does it take it to hit the floor. The vertical velocity changes by 9 8 m s each second of motion. Projectiles are objects upon which the only force is gravity.

Place the cpo launcher near the edge of a student desk. The launcher can launch at angles from 0 horizontal to 90 degrees vertical. On the other hand the horizontal acceleration is 0 m s s and the projectile continues with a constant horizontal velocity throughout its entire trajectory. Write down the equations of motion.

If the vertical velocity component is equal to 0 then it s the case of horizontal projectile motion. You can use a bubble level to align the. A the time of flight assume down is positive. Put the timer in interval mode and connect the photogate to input a.

Easy to read protractor allows for precise measurements and calculations. The test involved launching the object and measuring the initial height angle and the displacement of the object. Three vectors v vx and vy form a right triangle. Velocity of the marble can range from 3 m s to 9 m s.

The assignment was to create a projectile launcher to test if increasing the initial angle of an object marble would increase the total displacement of the launched object. Gravity being a vertical force causes a vertical acceleration. Use the vernier projectile launcher to investigate important concepts in two dimensional kinematics.
