Investigation into the Factors Affecting the Speed of a Trolley on a Slope

APPARATUS:

* 1kg Trolley

* 1kg Masses

* Runway

* Light Gate

* Stop clock

* Power Pack

* Ruler

SAFETY:

* Make sure all wires are secured in sockets.

* No wires are trailing on slope.

* Voltage of light gate has to be between 9V and 15V.

* Weights must be put on trolley safely so there is no chance they might fall off.

* When putting more than 2 weights on, stack safely.

* Turn electricity off after use.

* Before use make sure electricity is switched off so not to get a nasty shock.

In this investigation I am going to set up a 1kg trolley on a slope and I will be letting it roll. I will use a light gate to start and stop the stop clock using a piece of card measured at 10 cm.
Join now!


I will find out the speed of the trolley by dividing the distance (10cm) by the time that was read on the stop clock. The results are shown on page . For each reading I will repeat it 3 times on each side of the slope and find the average, thus making this a piece of reliable evidence. I will be investigating the speed at 5 different heights ranging from 1cm to 13cm, and on each height I will be varying the mass of the trolley from 1kg up to 5kg.To make it a fair test I will ...
