The Effect of the Height of a Crater on Its Diameter
Introduction
============
A crater is formed when a meteor for outer space strikes the lunar
surface. The force of the impact obliterates the meteorite and
displaces part of the moons surface, pushing the edges surrounding
rock. At the same time, more displaced material shoots outward from
the crater.
I will simulate this in the classroom by using a margarine tub full of
sand and using different heights to represent the distance it
travelled. I will then drop the balls from my chosen heights.
The sand = The moons surface.
The balls =The meteors
Variables:
All the variables that I can change and what can affect my experiment
are;
* The height in which I drop the ball from.
* 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 angle of which the ball hits the ground.
All of these changes could affect my final results. I will have to
take these into consideration when doing my experiment.
Aim:
I have chosen to do the different heights that I drop the ball from. I
will use only one type of ball to keep my results the same. In the
experiment I will be measuring the diameter of the crater and see how
the height effects this.
Labelled diagram:
I will measure the diameter of the creator using a compass then
measure the width of the compass against an accurate ruler.

Most amateur golfers believe that impact on the ball is the only key factor for hitting straighter and farther by swinging harder and faster, forgetting important facets in basics of the swing. There are multiple parts of the swing that involve biomechanics however; some key points are set-up, backswing, downswing, follow-through, and ground reaction force (GFR). To focus primarily only on one point of the swing to fix all problems is an obscure way to view the s...
Transition: First, I want to talk about the equipment used in the game of bowling.
First, take the golf tee and insert it into the ground with the needle-like bottom down. Then, place the golf ball on the platform of the tee. The tee should be set at a height of comfort for the golfer. The size of the driver head, or part that comes into contact with the ball during a swing, should be taken into consideration because the middle of the ball should be struck with the sweet spot, or middle of the clubface.
the ball would not come my direction. I have never had good luck, so the ball
The first thing that you have to do in your wind up is to step back with your right foot behind the rubber. Second you have to swing you right foot up and balance on your left foot. Finally you have to push your left foot off of the mound while balancing and throw the ball towards the plate. After you throw the ball you have to be in a fielder’s position in case the ball is thrown hit back at you.

The independent variables in this experiment are the height of the ramp, the length of the ramp, the surface of the ramp, the weight of the marble, the size of the marble, and the surface of the marble. The dependent variable is the distance the ball rolls. The controlled variables are the starting position of the ball, the angle of the ramp, and the surface of the floor. Units: The height of the ball from the ground, the height of the ramp, and the distance the ball rolls will be measured in centimeters (cm).
back it should still fall in), letting the ball go at the same time as
Investigating the Effect of Drop Height on the Depth of Sand Aim: To investigate the depth of the sand depending on the height at which the ball is dropped from. Variables: Independent variable chosen: The height at which the ball is dropped Dependent variable chosen: The depth of the sand after removing the fallen ball from it. Constant variables and how they will be controlled: Variable How we will keep it constant Amount of sand We leave the sand in the bucket and make sure that none spills over. Type of sand Use the same one for each trials Ball Use the same ball for each trial, with the same size, volume, material and brand.
The Sand Cone Model describes business improvement as a process which should be based on improving specific competitive dimensions in a different order (Meredith & Shafer, 2013). For instance, a business which is struggling with quality outputs should place an emphasis on improving the quality of its outputs first. Businesses that produce high quality outputs are successful over the long term. Matthew 7:24-25 (ESV) states, “Everyone then who hears these words of mine and does them will be like a wise man who built his house on the rock. And the rain fell, and the floods came, and the winds blew and beat on that house, but it did not fall, because it had been founded on the rock.” When a business builds its foundation on
There are many different types of volcanos on earth. Like the Cinder Cone Shield and Composite. All of these volcanoes are very unique.most of the volcanoes are made up from rock.
