Acceleration 3

Investigating motion as force is changed

Method

The trolley is released.  The force caused by the weight of the masses moves the trolley.  The light gates note the time as it passes  each one so acceleration can be calculated.

Conclusion

As the weight increases there is a stronger force pulling the trolley and the acceleration of the trolley increases.  As force doubles the acceleration also roughly doubles.

A graph of force and acceleration produces a straight line through the origin.   This tells…
