EXPERIMENT NO. 6: DOES HEIGHT INCREASE FINAL VELOCITY?
After running the last of the mini experiments - with the last of the mini experiments - we asked if speed makes a difference with depth to which we threw a ball into the flour and dropped another one into the flour - and notice that it does.
After that, we ask if height the ball is dropped makes a difference? To which they reply that yes it does. When pushed further - they answer that it increases the speed (final velocity). This was the question & hypothesis that created the perfect segway into the next lab: Does height increase a balls (average) velocity?
Experimental Design:

This was the question & hypothesis that created the perfect segway into the next lab: Does height increase a balls (average) velocity?
Experimental Design:
- What we want to know is if height increases a balls final velocity before impact.
- To test this, we're going to drop a ball at various different heights on a ramp and measure the time it takes for it to reach the bottom. We're using a ramp to slow down the downward decent and measuring the heights at every 30 cm interval of the ramp.
If our hypothesis is correct, we should see an increase in speed as we increase the height.
Results:
Results:
We are seeing two strong trends in both graphs.
Conclusion:
Yes, height does increase the final velocity of a falling object.
- With graph 1 & 3, (Time v. Height, Height v. Time) We notice that even though it takes more time to get to the base of the ramp, it seems to do so at a quicker pace.
- Graph 2: (Height v. Speed) On this graph, we're noticing that the speed is gradually increasing as we increase height.
Conclusion:
Yes, height does increase the final velocity of a falling object.
