Acceleration and Force Experiment (Constant Mass) - GCSE Physics

This video demonstrates the experiment we can do in order to investigate the relationship between the acceleration of an object (with a constant mass) and the applied force.

The experiment involves a trolley that can be connected to a phone, some masses and a piece of string. By dropping some of the masses off a table, we can cause the trolley to accelerate. This acceleration is the acceleration due to gravity. We change the mass of the trolley and the mass that's dropped but the total mass does not change. By changing the mass that's dropped, we change the force acting on the trolley. The force acting on the trolley is equal to the weight of the mass that's dropped.

Once we have our readings, we can plot them on a graph to investigate the relationship between acceleration and force.

The blank and filled in results tables can be found here:

Superb. Crystal clear explanations. Thank you.

[nithilalogathas]

Thank you so much! I'm just really worried about my A Levels this year; it seems like it comes down more to luck and how much the teachers know you for good grades. Your videos help me to hold on to that string of hope that maybe the 'mini tests' would be a heavier weighting than teacher assessments. Thanks again.

Lol, may the force be with you. 🙂 Thank you for the tutorial.

Hi..can u share the apps to measure the acceleration in the experiment?

[saiki]

what if the mass applied on top of the cart is not given but the one hanging off the edge is, how could i find out what the mass applied on the cart is?

[LaraB-mb]

Is anything changing in the experiment if the mass is constant? If so, what would the independent variable therefore be?

[blqees]

is the mobile application did you use?

[manolawroaa]

If I want to buy this cart and all the demonstration where I can get them online

[na_ndii]

Hello where can I find the results video, thank you for this I was drowning

[samuelbanner]

unfortunately i now think heavier masses fall quicker

[bavelleymokwena]

What are the apparatus used in this expriment

[Harry-cxx]

im a bit confused as to what part of the mass is staying the same in this experiment, as you are removing mass from the trolley, and adding it to the string, right???

[shahdmeziati-mine]

sirrr uno on your website how do I know what is triple and what is not and whats higher or foundation
