The Effect of Height of a Ramp on the Speed of a Trolley

For this piece of coursework, I intend to investigate the relationship

between the heights of a ramp to the change in speed. I will be

measuring the speed from these heights: -

* 5cm

* 10cm

* 15cm

* 20cm

* 25cm.

Formula

AIM

The aim of this investigation is to find out what the relationship his

between the height or a ramp and the change in speed.

Hypothesis

The greater the height of the ramp the more the speed of the trolley

would increase.

Hypothesis Explanation

The greater the height of the ramp the more speed of the trolley would

increase. The change in height increases the change in speed; this is

because the higher the ramp the more gravitational potential energy is

stored. The reason is the Gravitational potential energy is the energy

stored in an object as the result of its vertical position in this

case it’s the height of the ramp. The energy is stored as the result

of the gravitational attraction of the Earth for the object. In this

experiment I am trying to find out the relationship of the height and

the change in speed; which is a direct relation between gravitational

potential energy and the height of the ramp; the higher that the

trolley is elevated, the greater the gravitational potential energy.

Prediction

I predicted that the more the ramp increases in height the more the

change in the speed will also increase. I also think that the

relationship between the height of the ramp and the change in speed

will be directly proportional.

What will be done throughout the experiment?

I will do my experiment by:-

* I will firstly I will get everything I need for my experiment.

* I will then use a small pile of books and set the ramp up at the

first height of 5cm.

* I will next make sure that the stop watch is ready to start, meaning
