Vertical Marble Launcher Diagram

Use this diagram to answer questions 28 through 30.

Vertical marble launcher diagram.

Shown in the diagram to the right. R 2 vx vy g. Projectile motion lab purpose determine the initial velocity of ball launched horizontally predict and verify the range of ball launched at an angle equipment. Compare the time it takes for the cart to travel from x to z.

Attach one photogate to the marble launcher so that the marble breaks the light beam as it comes out of the barrel. T 2 vy g range of the projectile. Vx v cos α vertical velocity component. Stopwatch might be needed for part 2.

Uff that was a lot of calculations. Vy v sin α time of flight. Let s sum that up to form the most essential projectile motion equations. A marble launcher shoots a marble horizontally from the height of 0 2 m above a horizontal floor.

Place the cpo launcher near the edge of a student desk. Cart eventually lands at point z. Use the graph to the right for questions 6 through 8. Launching the object from the ground initial height h 0.

Marble either a plastic or steel marble my group selects the marble meter stick. The vertical velocity changes by 9 8 m s each second of motion. C setting up the marble launcher c 1 1. This angle will be the angle θ of the initial velocity v o.

Put the timer in interval mode and connect the photogate to input a. Gravity being a vertical force causes a vertical acceleration. Projectiles are objects upon which the only force is gravity. Procedure for the horizontal launch to find the device launch velocity.

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. The marble launcher has different angle settings from 0 to 90. For this experiment you will use angles. The angle can be changed by untightening the large knob on the rear of the launcher arm of the marble launcher and rotating the launcher arm to the appropriate angle then retightening the knob.

The object s vertical displacement as a function of time.
