# Isaac Newton's second Law of Motion states that, Force = Mass x Acceleration.

Extracts from this document...

Introduction

Newton’s Second Law Coursework

## Introduction

Isaac Newton’s second Law of Motion states that, Force = Mass x Acceleration. For this project I intend to prove or disprove this theory.  The fact that the Law has survived 300 years of evolving science provides much of the needed evidence that the Law is truthful and works but I will do the experiment to determine my own set of results.

## Newton’s Second Law

Newton’s Second Law is a way of finding the force that is acting on a certain object by using the known mass of the object and the projected acceleration and that the mass is inversely proportional to the acceleration.

For example, A bus keeps going forward because the forces of acceleration and friction are unbalanced but as soon as these forces become balanced than the bus will keep a steady speed.  It is this that I am going to investigate.

The Law can be tested quite easily by using a simple test, involving a trolley, a ramp and some weights.

Middle

A list of the equipment I will need is shown below:

1. A Trolley
2. A Two Metre long ramp
3. A Ticker Timer
4. Ticker Tape
5. A Pulley – so when we let the weights drop there will be as little friction as possible.
6. String
7. 5x 1Newton weights

We will measure the acceleration caused by a certain weight three times to make sure we get the right results.

## The Variables

• Mass
• Acceleration
• Force
• Friction

See page one for variables being tested.

## How to make it a fair test

To make the experiment fair, the only variable that I will change is the amount of weight that is used to pull the trolley down the runway.  All the other components i.e. length of string, height of runway, and stated variables will be kept the same.

## Prediction

Based on the results that we obtained when we used Newtons Theory to work out the projected accelerations for each different weight, I would say that the more weight that is applied to pull the trolley down the ramp the more the trolley will accelerate.  This is because the trolley has an unbalanced force which means it will accelerate.

Bearings and lubrication are used to reduce friction between a wheel and its axle. The ball bearings reduce the area of contact between the moving surfaces. The oil between the bearings, wheel and axle acts as a lubricant by separating the moving surfaces with a thin layer of liquid (we

The next scientific that I will look at is that worked on by the famous scientist that I have already mentioned - Sir Isaac Newton. During his work he discovered some laws of motion, which are quite appropriate to what I am investigating: Law 1: Any object will continue to

as m2gh, as only the dropping weight has g.p.e. The letter 'g' is the gravitational constant, and is approximated as 9.81. The letter 'h' is the height. Equally, k.e. is 1/2(m1+ m2)v2, as both the dropping mass and the trolley will move. By Law of Conservation of Energy, energy can neither be created nor can it be destroyed, however it can be converted from one form to another.

2. ## An investigation into the acceleration of a trolley up a ramp.

I will be using a ticker tape timer to measure the acceleration. This will be attached to the trolley using 'blu tac' and the trolley will have a mass of 500g in addition to it's original mass. The trolley will be attached to a pulley which in turn will be attached to a mass that will be varied.

1. ## What affects the acceleration of a trolley down a ramp?

Friction Friction is a force linked to movement; it slows things down, or stops them from moving. The direction of the frictional force is always opposite to the direction in which the object is trying to move. Friction arises because of the roughness of the two surfaces that are moving
