# Investigating what effects the acceleration of an object; will its mass or the force acting on it effect the acceleration.

Extracts from this document...

Introduction

Aim: I am trying to find out what effects the acceleration of an object; will its mass or the force acting on it effect the acceleration. In order to carry out this investigation I will do two experiments. Firstly, I will add a mass on to the end of a trolley and a piece of ticker tape will be attached to the end of a trolley, which will go through a ticker timer, which is a piece of equipment that has a vibrating mechanism inside of it that once on will make dots on a piece of ticker tape, once the trolley finishes you can see on the ticker tape that the dots will be farther apart from the last showing acceleration. ...read more.

Middle

timer once the trolley finishes you can see on the ticker tape that the dots will be closer together not farther apart like the last experiment. I will do this three times adding more weight each time, which will make the trolley go slower than the last. Fair test: I will change the mass upon the trolley, which will and slow it down depending on the mass. I will also change the force pulling the trolley, which will fasten it up depending on the force. I will keep the trolley the same size for each force experiment, also the force for each of the mass experiment so it will not influence the results. ...read more.

Conclusion

Prediction: In the experiment I am about to complete, I predict that if I add more force to an object it will increase the acceleration. A force of two Newton's will pull an object harder than a one Newton weight, increasing the acceleration, and if I add three Newton's it will pull an object even harder giving an enhanced acceleration than before because the more force the faster it will go increasing the acceleration. I also predict that if you add a mass onto an object it will decrease the acceleration. A mass of two kilogram's will slow an object down more than one kilogram, giving a decrease in acceleration, and if I add three kilograms, it will slow down an object further than before. ...read more.

The only type of change in velocity I have not shown is deceleration. Deceleration is when the trolley reduces its velocity. This can be represented on a ticker timer tape by the dots first having big spaces in between them and gradually the space between each dot gets smaller and smaller.

2. ## Investigating the relationship between force, mass and acceleration

We would expect these relationships because: Evaluation: This experiment has worked well as we were able to prove the hypothesis quite accurately. The experiment allowed us to calculate the acceleration very accurately and was relatively easy to carry out. We encountered a few problems, and improvements need to be made to improve the accuracy of our results.

The weight will give a constant force. The gravity will be the same, using a falling mass tied with the string I can provide the trolley with a constant force and now in this investigation it has been proved that Acceleration= force/mass Is correct.
