Marble Ramp And Acceleration Lab

Physics 31210 lab 2 projectile motion introduction.

Marble ramp and acceleration lab.

Modeling the marble ramp lab. Although the marble only has a change in speed and not direction we can still determine that acceleration occurred due to the definition. Roll the marble from the top of the plank. In this part the distance rolled down the ramp and the angle of slope are both variables.

By rolling a steel marble down a ramp and measuring its horizontal range you can calculate the marble s launch velocity. The steepness of the incline can be measured by the ratio of height to length. Because the marble gains speed as it travels down the ramp it has acceleration. To confirm this velocity with an independent measurement you can use a photogate.

In groups of 3 begin by picking one person to be the marble starter 1 person as distance marker watcher and one person as timer. In this lab we measured the acceleration of a rolling ball down a ramp at a specific height. Record your distance in the data table. Set up your lab station as follows.

I choose a fishbowl to introduce this activity instead of a lecture or a recipe lab because i want students. A traditional fishbowl is a teaching strategy where students contribute to a discussion or activity. Roll the marble down the longer ramp for increasing amounts of time one second two seconds three seconds etc until the time the marble goes past the end of the ramp. Our variables in which we used to determine speed was a little metal ball and a metal black ramp we placed the ball on to measure its speed.

This relates to the lab results because as we determined the marble gained speed as it advanced down the ramp.

We marked this ramp at each distance in which we were starting the ball from.

Measure the total length of the ramp and record in data table b as l. Bell ringer marble ramp lab.
