Hypothesis: The increase of the ramps angle is directly proportional to the ball's time of speed. The object rolls without slipping down the ramp. This page: Rolling Motion looks at the situations when the ball is rolling without slipping and when it isn't. Each case, however, gives a different formula for the force imparted by the contact of the ball with the incline. The applet then displays the motion of the ball as well as position, velocity, and acceleration graphs in real time. Use suvat equations to work out the speed and acceleration ect of the ball and you can easily work it out. To switch between accounts click on the account below. A really simple way to solve the dynamics of this system is to split the ramp into, say, 100 elements then compute the acceleration of the ball at the start, integrate the acceleration to get the velocity at the next point. This is not realistic at very large angles of incline. To do this you will want to mark out eight evenly spaced marks on the ramp and take note of the time that the ball crosses each mark (Image of what the ramp should look like below). Optional (to show angle of plane and related frictional effects). Galileo's hypothesis was that balls rolling down ramps of equal height would reach the same velocity as a free-falling ball no matter the slope (steepness) of the ramps. The AIP Style presented is based on information from the AIP Style Manual. With friction, there is both translational and rotational kinetic energy as the ball rolls down the ramp. Interact on desktop, mobile and cloud with the free WolframPlayer or other Wolfram Language products. The cube slides without friction, the other objects roll without slipping. Contact us! Because timing and other factories like wind resistance are an issue at great heights (like dropping a ball from the height of a building), Galileo and fellow scientists used inclined planes, like ramps, to conduct their experiments.
