How high, how far?

The aim:

The aim of this experiment is to change the angle of a ramp and place a trolley 70 cm away from its edge and release it and see how far the trolley travels off of the ramp.

Prediction:

I predict that the smaller the angle between the ramp and the desk (the less steep) the less the trolley will travel off of the ramp and the larger the angle between the ramp and the desk (the more steep) the more the trolley will travel off of the ramp.

I think this because if the ramp is steeper the trolley will accelerate more as it goes down it and it will travel further and if the ramp isn’t very steep then the trolley will not accelerate very much as it goes down it and it wont travel very far.

Equipment needed:                                       Equipment set-up:

Desk/floor

Ramp

Trolley

Metre Sticks

Calculator

Textbooks

Fairness:

To make this experiment fair I have to make sure that:

  • I put the textbooks under the ramp at the same place each time
  • I make sure that the front of the trolley starts at the 70cm mark
  • I make sure that I let the trolley go rather then push it down the ramp
  • I do each test three times and average out the result
  • Our trolley isn’t biased to one side when it rolls

Measuring:

To find out the distance travelled by the trolley from the end of the ramp I will use a metre stick and will measure from the base of the ramp to the front of the trolley where it has stopped on the desk/floor.

I measured the height of one textbook and found it to be 2cm high, and I made sure that the edge of the textbooks that were holding the ramp up were lined up with the 70cm mark that we made on the ramp.

For each experiment we counted up the number of textbooks and from ...
