Run the following experiments:
Test the hypothesis that the
acceleration of a given 'beam' coasting to rest on a die is independent of its
average speed.
- Spin a 'beam' on a die and measure
through what angle it coasts and how long it takes to come to rest. Take
at least 10 measurements.
- Graph acceleration vs. coasting
distance for the 'unloaded beam' and for the 'loaded beam'.
Test the hypothesis that the
acceleration of the 'beam' is influenced by the mass of the 'beam':
- Place balanced masses on the ends
of the 'beam' and repeat the experiment.
Observe a 'collision' between a pearl pendulum and the 'beam':
- Collide the pendulum with the beam, with the beam initially
at rest.
- Observe the length and pullback of the pendulum, where it
hits on the 'beam', how far the pendulum bounces back and how far the 'beam'
coasts before coming to rest.
-
- For each trial calculuate, based on PE change, the initial
velocity of the pendulum and its rebound velocity.
