Vertical Marble Launcher

Easy to read protractor allows for precise measurements and calculations.

Vertical marble launcher.

The launcher can launch at angles from 0 horizontal to 90 degrees vertical. You can use a bubble level to align the. Gravity being a vertical force causes a vertical acceleration. Use the vernier projectile launcher to investigate important concepts in two dimensional kinematics.

Place the cpo launcher near the edge of a student desk. The vertical velocity component vy is equal to v sin α. B how far from the table will it hit the floor. For this experiment you will use angles from 0 to 80 degrees.

Velocity of the marble can range from 3 m s to 9 m s. Projectiles are objects upon which the only force is gravity. Launch steel balls at angles between 0 and 70 degrees and over distances up to 2 5 m. Three vectors v vx and vy form a right triangle.

A the time of flight assume down is positive. B the horizontal distance. This design of a marble launcher uses a plunger that is pulled back inside of the barrel so that a compression spring begins to compress and create potential energy once released the spring drives the plunger through the barrel which forces the marble out of the barrel. The vertical velocity changes by 9 8 m s each second of motion.

The solid heavy base provides an easy to use and reliable setup. Arrange the desk in a way such that the direction of launch will be clear for at least 4 meters. Marbles can be launched from five different speeds at any angle between 0 and 90. Extra problems 1 a car dnves offa wharf at 15 m s if the wharf is 25 m above water calculate.

Put the timer in interval mode and connect the photogate to input a. 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. 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. 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 test involved launching the object and measuring the initial height angle and the displacement of the object. Write down the equations of motion. If additionally α 90 then it s the case of free fall.
