Physics/Adva nced Physics The Ramp simulation Name K'24=Â Hr. Open up the following website: http://phet.colorado.edu/simulations/sims.php?sim=The Ramp and click (/run now." The simulation allows us to explore forces and motion on a horizontal surface and on a ramp. This simulation allows us to change different features: object and its mass, the angle of the ramp, the frictional characteristic of the ramp surface, etc. Part A) Learning a bit about the simulation. First off, when you open

stimuli would be the bear. The process is constantly repeated all the time, our body gas sensors that constantly received information of the environment. This information travels in waves. The motion of waves like any other element is bound by forces that can change both the magnitude and direction of a motion. Newton's Laws required waves to be generated by some energy. Without energy there is no motion and without motion there is no wave. Let’s consider a pendulum. If we observe

Phvsics Lab Report Format (Sample Report Attached) General Remarks: Writing a lab report is the only way your TA will know what you have done during the lab and how well you have understood the process and the results. Part of your lab experience should be learning how to organize and present your work in a scientific way. There is no framework that can be used as a "one size fits all", therefore this sample lab report should only be used as an example. Any lab report should have the
