Physics Investigation

Introduction

In my investigation I intend to gather enough evidence and explanation to see if and how the mass of a ball will affect its stopping distance.

I will carry out a series of tests starting with changing the mass of the ball then changing height which it's dropped from.

Predictions

I predict that the mass of a ball will most defiantly affect the distance it takes to stop because as the mass increases, the amount of friction with the surface will increase which will slow down the ball sooner.

I believe if the mass of the ball is doubled the friction with the surface it's on will double and therefore half the distance taken to stop.

Equipment

For my investigation the equipment I will require is:

* A ramp and stand ( 1 metre long)

* Carpet (2 by 0.5 metres)

* 2 balls of different masses but same size ( ball 1, 2.8g and ball 2, 44.9g)

* 2 metre rules

My setup

My setup is pretty simple I will use a ramp with a rule along it and some carpet for
