Investigation to find out what affects the size of a shadow.
Hypothesis I predict that the closer the object is to the light source the larger the shadow will be. Therefore the further away the objects from the light source mean the shadow will be smaller. This is due to many factors regarding how light travels and the distance to object lies from the source light. We know that light travels in straight lines so when an object is place in front of a light the light cannot travel around the object or through it so the object blocks out the light. This means that if the objects are closer to light the light source the more light is blocked out.

Electromagnet Investigation
When the domains are pointing in one direction a magnet is made. The strength magnetic field produced by the solenoid is then increased greatly. The higher the current passing through the coil the stronger the magnetic field this is because there will be more electrons (e ) moving there will be. Without being placed in magnetic field. With being placed in a magnetic field. (Solenoid coil) If the double the amount of turns we will get double the amount of electrons moving in that location or area, increasing the magnetic field because of smaller individual magnetic field will merge making a tug of war effect.

Hockey Skills
The field players can be put into three general categories  attackers, defenders and midfielders. While no player (other than the goalkeeper) has an exclusively defined role, the attackers are generally on attack, the defenders are generally on defence, and the midfielders do a bit of both! Stick handling An essential skill necessary for playing hockey is the ability to control, pass, push, stop and shoot the ball with your hockey stick. This is known as stick work, or stick handling. It is both beautiful and impressive to watch a player with good stick handling skills control the ball while sprinting the length of the field, or weave through the sticks and legs of defenders to create an open shot.

Investigating the Mechanics of the 100 Metre Sprint
Initially the athlete should concentrate totally on his starting technique, which he has finetuned in training. Irrespective of the lane or adversaries, he now focuses on a smooth acceleration towards attaining his maximum speed. Once he has attained his top speed, he now relaxes totally in order to maintain his speed with the least amount of unnecessary interaction from muscles or parts of the body not being used for sprinting. The finish also requires some though because a centimetre gained by a correct finishing technique can win a race, a positive and active forward lean can help to achieve that.

Charge To Mass Ratio For An Electron
Comparing this experimental value to the theoretical value which is 1.76�1011 coulombs/kg makes a 7.38% experimental error. One of the reasons that this error can occur is related to earth's magnetic field and causing force on the electrons. In conclusion a charged particle will experience a force when moving through a magnetic field and also as the radius of the coil increases as electron flow the magnetic filed decrease. This can also prove that these two are inversely proportional. Introduction In 1897 J.J. Thomson made the first measurements of the charge to mass ratio of an electron (e/m), using cathode ray tub.

Simulating Asteroid Impact
for objects moving towards the Earth. In other words a falling object has a negative displacement. For objects moving away from the Earth, d will be positive (+). Notice that time, t, is still a part of equation (2). By substitution, we can eliminate t and can then calculate vf based solely on the distance the object falls. The initial velocity in these experiments is equal to zero, since the ball bearing is not moving prior to being released. This then simplifies the equations (1) and (2) to: (3) vf = gt (4) d = 0.5gt2 By manipulation of equation (3)

The Physics of Curling
to guide the stones from a fixed distance and as proximal as possible to a center target. Furthermore, there are two sweepers that attempt to guide the stone as close as possible to the center target(similar to a target one would see at an archery range except this target is embedded into the ice)  the game requires an immense amount of strategy and hitting the stone (which is essentially the puck) at tactical angles while taking into consideration physical forces which is where the beauty of physics comes into this sport as it does with essentially almost every aspect of nature.

The physics of riding a bicycle entails many different properties.
A bicycle was at one point the epitome of modern moving conveyance. The invention of the wheel allowed this. Previously, everyone had to walk everywhere they had to go. In the rain, sleet and snow, walking was the main mode of getting from ?here? to ?there?. The bicycle has taken different forms. There have been tricycles, a bike with three wheels, and a unicycle, which was used in circuses that had a rider on one wheel. When I first learned how to ride a bike, I fell a lot.

Use the following terms correctly in describing the forces and elements of a roller coaster.
There are actually two specific types of energy involved: potential and kinetic. A roller coaster cart has a large quantity of potential energy at the top of a hill. Potential energy, which is stored energy that depends on the mass and height of the object, is high at the top of the hill because the cart is very high off the ground. As the cart descends down the drop, it loses potential energy in accordance with height. However, the cart subsequently gains kinetic energy, which is the energy of motion that depends on the mass and speed of the object.
