of the cart will decrease as more weight is added on top of the cart. This is because the more weight that is placed on the moving vehicle/object‚ the more downward force is produced. This would increase the friction between the wheels of the cart and the ramp’s surface. The increase in friction would slow down the moving object (cart). Apparatus Trolley/cart- this is essentially a wooden block with wheels and a rubber end‚ to provide the collision with a cushion upon impact. Weights- these

This is what I am trying to find out In this experiment‚ I will be trying to find out how the height of the ramp affects the speed of the car. Variables Independent Variable The independent variable is the height of the ramp Dependant Variable The dependant variable is the time it takes for the car to travel down the ramp‚ with that I will calculate the speed. Control Variable The control variables are the same person timing and releasing the car‚ same type of car‚ same ramp‚ same starting

is made up of five layers. The first is the stratum corneum. This is made from dead‚ mature skin cells called keratinocytes. These cells are constantly shed. The second layer is the stratum lucidum. This is found in thicker skin and helps reduce friction between the stratum corneum and the stratum granulosm. It is made of flattened skin cells. The next layer is the stratum granulosm. This is where keratin is formed. This layer produces materials and prevents evaporation‚ which keeps the skin waterproof

ADVANTAGES AND DISADVANTAGES OF PRESTRESSED CONCRETE ADVANTAGES : Use of high strength concrete and freedom from cracks‚ in prestressed members‚ contribute to improved durability under aggressive environmental conditions. The use of high strength concrete and high tensile steel in prestressed concrete members results in lighter and slender members than could be possible by using reinforced concrete and Mild steel as reinforcement. In prestressed concrete‚ steel is no longer required for

Running head: ROLLER COASTERS Roller Coasters: History‚ Physics‚ and records Abstract This paper explains the early history of roller coasters from their rough beginnings in Russia through the migration to the United States. It goes on to emphasize the important physics that go along with how roller coasters operate and the forces that work with and against it. In the end it talks about what records and accomplishments have been made with the usage of roller coasters. Formal Outline I

research about long distance mousetrap cars. We found that there were five elements that we needed for our car: reduce friction bearings‚ longer length lever arm‚ large diameter drive wheels‚ small diameter axel and lightweigth components. After getting those characteristics we drew a desing following the five elements and using only three wheels instead of 4 to reduce friction by taking apart rolling bearings of one wheel. The next step was to find the right materials. Our team got a mousetrap

Weatherspoon‚ Chloe Parry‚ Miya Reyes‚ Juan Mousetrap Car Project Report Purpose: The purpose of this project is to build a mouse trap car and apply it to Newton’s laws of motion. Newton’s first law states that every material object continues in its state of rest or in uniform motion in a straight line unless it is compelled to change that state by forces acting on it. Newton’s second law states that the acceleration of an object is directly proportional to the net force acting on the object
