# Craters Investigation

Extracts from this document...

Introduction

## Craters Investigation

In this experiment I am going to investigate one factor that causes craters to be different sizes. I am going to do this by dropping a ball bearing with a mass of 63.7g, from varying heights into a tub of sand and then measuring the width of the crater it made.

## Research

On the Moon, craters usually measure up to 200 (320 miles) or more in diameter. Meteorites hitting the lunar surface at high velocity produced most of the large craters. Many of the smaller ones - those measuring less than 1km (0.6 mile) across could have been formed by explosive volcanic activity.

Many craters have a surrounding ring: this is usually quite low although a typical one may be about 1500m (4920 feet) above the surrounding landscape. In many cases, there is a central peak or several peaks within a crater.

The darker areas of the Moon, known as Maria, have relatively few craters. They are thought to be huge lava flows that spread over an area after most of the craters have already been formed.

## Apparatus

· 1 Tub of sand

· 1 Ruler

· 1 Metal Ball Bearing (63.7g)

Preliminary work

For my preliminary work I decided to test my experiment at the two extremes. These will be the smallest height I intend to drop the ball bearing from and the greatest height I intend to drop it from.

These are; 10cm and 100cm

The results I got were:

 Height dropped from Width of crater 10cm 42mm 100cm 90mm

My preliminary work has been positive because I have found that 10cm is a sufficient height to drop the ball bearing from to give me a decent result, the crater is not so small that I cannot read its width easily. I have also found that 100cm is not too high to be accurate with where the ball will land and it does not splash too much sand out of the tray.

Width of crater (mm)

On my first set of readings I had a few anomalous results that I have highlighted in red on my chart, I have repeated these results and written then next to the original ones. I then took the average from the repeated results.

At first I couldn’t tell if the line on my graph was a curve or a straight line. To find out if my graph would level off I tried dropping the ball bearing from 2 metres, twice my maximum height of 1 metre. So if my graph were a straight line it would be a very big crater. However the crater was only 95mm, which is only 10mm bigger than my result from dropping the ball bearing from 1 metre. This shows that the graph would eventually level off. This means that the graph is a gentle curve.

This student written piece of work is one of many that can be found in our GCSE Electricity and Magnetism section.

1. ## Does the height of a crater affect the diameter of the crater produced?

* The amount of sand in the tub. * The size of the different individual balls. * The weight of the balls. * Speed of which the balls are travelling at. * The surface type. The only thing I am going to be changing is going to be the height of the ball in which it is dropped.

2. ## physics of the bouncing ball

As the ball falls the gravitational energy is converted to kinetic energy so the ball accelerates as it falls. When a ball is higher it will fall, and accelerate faster and hit the ground harder, bouncing up higher. Having even less gravitational energy when being dropped from 70cm once again all the balls decreased in bounce height.

Therefore mass is the independent variable. As an independent variable, it simply means I will need to change the mass throughout the experiment in order to demonstrate a possible influence. I have chosen mass because I believe this will have a powerful relevance to the shape, size and depth of

2. ## Physics Coursework Gravity Investigation

more the ball compresses and the more strain potential energy the ball has. The strain energy causes the ball to expand creating the ball to exert another force pushing off from the floor. The forces are now unbalanced and the ball thus ascends to its' bounce height.
