    Factors Determining the Stopping Distance of Rollers Down a Ramp Theory- ------- When the roller is rolling down the slope then potential energy is converted to kinetic energy that converts into heat energy. MGH = ½MVsquared The loss of kinetic energy on the carpet is …. ½MVsquared = braking force x braking distance therefore…. ½Mvsquared = F x so MGH = F x [IMAGE] If m, g and f are constant then…. [IMAGE] However if G is constant then…. [IMAGE]

    Investigation of the Relationship Between Mass of a Vehicle and Its Stopping Distance Problem The problem to be investigated is "how does the mass of a vehicle affect its stopping distance when brakes are applied?" This problem is related to the conservation of energy and will be investigated through a trolley going down a ramp. A simple trolley will be used to represent the vehicle and weights attached to the rear of the trolley via a pulley system will act as the brakes. Throughout the

    throughout the years. Once considered one of the simplest parts of a vehicle, brakes have become one of the most complicated components in a vehicle. The scientific explanation behind a brake system is very rudimentary. Friction permits the concept of braking to occur. The first brake system was used thousands of years ago. The Romans had a system that involved a wooden block and a lever to slow and stop the cart. The driver would push or pull the lever which causes a wooden block to be pressed against

    lens of a lens is the distance from the principal focus to the optical centre. It is the point where the image comes into focus when seen though the lens. The focal length of a lens depends on the curvature of each surface. So the more highly curved the surface, the shorter is the focal length and visa-versa. In this experiment the lens is first placed at L1, between the screen and the illuminated object. When the illuminated object comes in focus on the screen the distance of L1 from the illuminated

    Investigation of Whether the Quality of Environment Changes with the Distance from the CBD in Lisburn My Survey was going to be limited by time. We had to look at an area from the centre of the town to the edge. I chose a transect across the town, west to east. The total length of the transect is 2.5 km., selecting sample points every 100m on gridlines - 12 western, 12 eastern. See map Appendix 1. We needed a map of the transect lines, data collection sheets, camera, clipboard and suitable
