![]() This means that, in order for the ball to make it all the way around the loop, it must start at a height at least half a radius above the top of the loop, or 2.5 radii above the ground. ments reveals that most of the kinetic energy of the falling. This can be inserted into the first equation to substitute the known parameter R for the unknown v: explain the physics of this system to their students without justifying the assumptions and. on the falling block, slowing it down, and the block does not break the chalk. Otherwise, the ball will not make it all the way around the loop and will just fall. a) Consider a 1-kg block with a flat bottom and a string attached to the. The acceleration of a rotating object following a circular path of radius R is given byĪt the very top of the loop, the acceleration must be at least equal to g to counteract the gravitational force. Using both ideas in conjunction, you can calculate that you need to start the ball at a height h > 5/2 R and then test this prediction on the track.Ĭonservation of energy states that the change in potential energy equals the change in kinetic energy, or Simultaneously demonstrate rotational motion and conservation of energy.
