The Size of Craters Formed by Falling Objects
Research
A meteor is a small body that orbits around the sun. They sometimes
enter the earth's atmosphere and burn up, due to the friction between
the body and atmosphere and hits the earths surface. When they hit the
earth's surface they are called meteorites. In Arizona, USA, a crater
was formed by a large meteorite; scientists estimate it hit the earths
about 500.000 years ago. A meteorite could also explain the extinction
of the dinosaurs, when it hit the Gulf of Mexico. Some meteorites have
dense lumps of iron and nickel, which show marks of slow cooling;
these may have come from the violent history of our solar system.
Hypothesis
Energy is never created or destroyed; it is just transferred from one
form to another. This is the principle of the conservation of energy.
In my experiment there are different factors that might affect the
size of the craters formed by the falling object, this includes the
size of the object I drop, if the object has a flat side the air
resistant will be larger, then for example a sphere, which will
decrease the speed of the object. In my experiment I will be using the
same golf ball for each of the tests.
The angle at which I drop the object will also affect the size of the
crater. To make it a fair test I will have to drop the object from the
same angle ever time. I will drop the ball from 90 degrees above the
surface of the sand, this will create a crater which is nearly even,
meaning that the radius from the centre to the outside edge of the
crater would be the same length. If the golf ball was dropped from a
shallower angle then the crater would be longer, but the diameter of
the crater would stay the same, as if the golf ball had been dropped
from directly above the surface of the sand.
When I drop the golf ball I wouldn't have to throw the golf ball in to
Dropper Poppers are rubber toys that resemble half a rubber ball and are shaped as hemispheres. They are turned upside-down (or inside-out), left on a flat surface, and after approximately 5 seconds, the dropper popper flies upwards, going higher than its original position. Simply put, the rubber needs to return to its original position, and creates a high surface tension. The rubber’s urge to return to its original position also causes instability within the structure of the dropper popper. When you drop the toy onto a flat surface, the inverted part pops back out, slams into the surface, and causes the toy to bounce into the air. This is a very basic explanation of what causes the dropper popper to act the way it does, and the physics principles
same as it was when the ball was first dropped as there is energy loss
to throw. Well the first thing that came to mind was just to fling it up in the
I am going to carry out an experiment to measure the change in mass of
This forces the outside of the ball to push out and therefore bounce back up to 2. However, the ball will not bounce back to its original position. original height due to it losing energy as heat and sound energy when hitting the floor. Relevant Variables The independent variable in this investigation is the height of the ball is dropped from the sand.
For my egg drop project, I made mine out of balloons. I got the idea from a YouTube video called, Top 10 FIRST PLACE Egg drop designs! Science Experiment Challenge! The channel name is IncredableScience. The first idea, ( on the video) was the one I created. I first wrapped my egg in duck tape and then attached balloons. Finally I connected all of the balloons together using duck tape. At first I wasn’t going to wrap my egg with duct tape, but I found this duck tape barrier helped to attach the balloons later on. I dropped it from my balcony which is about 10 feet and it survived. The weather conditions were not bad, it had just finished raining. I thought this would work because in the video I watched, the same balloon idea
(A way to test this is to hold a sheet of paper that is drooping and

below this height, where the kinetic energy carried into impact will. vary between different drop heights, I believe the bounce height will. also vary in the price range. As an object on Earth is dropped and bounces, the energy of that object will undergo a series of transfers. It begins with gravitational potential energy which is continually transferred to kinetic energy as it accelerates towards the ground.
In trial C, I used 14mL of baking soda. For the first launch the lid canister lid went 400cm. When it shot the lid hit the table. The second launch went 376cm, it started sizzling and the lid popped out then hit the table. The final launch went 500cm. The lid canister went past the table and hit the floor. The average distance was 425.3cm.
back it should still fall in), letting the ball go at the same time as
My topic for the science fair is “ Which falling objects fall the fastest? “. Many factors affect the speed of aerodynamics such as the different forces on the object. The aerodynamics of the object and the physics surrounding the object. Great scientists have studied falling objects such as Galileo Galilei and Sir Isaac Newton. I will discuss their lives, experiments and scientific findings.
Height of sand, compression Flatten or compress the sand back to how it was, as accurately as possible, by using a flat surface. Research Question How does the height of the drop affect the depth of the sand? Hypothesis As the height of the drop for the ball increases, the measured depth of the sand will increase. This is because the ball will have more time to accelerate at 9.8ms-¹, and therefore have more momentum, creating a larger impact on the sand each time the height of the drop is raised.
The possible sources of error are due to the confinement of the sphere by the walls of the cylinder, vibration during the time of the fall etc.
