potential. However‚ the car still traveled the the entirety of the 11 meters required for the maximum number of points. The reasons that my mousetrap car functioned as well as it did were: (1) the light and thin CD’s that I used as wheels minimized the friction between the car and the ground‚ causing the car to go a greater distance as opposed to the distance thick‚ heavy wheels would go. (2) The balloons that were wrapped around the wheels created traction and prevented the the wheels from slipping on

Force: a force that results when one object makes contact with another (pushes or pulls it) * Tension: a pulling force‚ with a rope/ string * Normal force: only when in contact with something ie. The ground. Points away from surface * Friction: opposes the sliding of two surfaces cross one another. Act opposite to the motion/ attempt at motion (electrostatic forces) * Force diagram-show all forces acting on object Newtons first Law: * Inertia: proportional to mass of the object

Hypothesis: If a car is involved in a crash‚ a domino effect of reactions will occur. Background: The modern day automobile is a very complex piece of machinery that has a lot to do with the world of physics. Like every great invention‚ there was a beginning. For the automobile this beginning was in 1769. Nicolas Cugnot‚ a Frenchmen inventing for the French Army‚ came up with was first self-propelled‚ steam engined‚ three wheeled cart that was said to go as fast as walking speed. The next

Introduction: In any pipe system there is going to be a loss of energy due to the effect of viscosity from a fluid acting upon the surface of the pipe‚ this is called Friction Loss. This type of lost depends on the shear stress due to the walls of the pipe and the fluid. It also depends in weather the fluid is laminar or turbulent. A major difference between these two flows is that due to a viscous layer created in turbulent flow the roughness of the pipe can be taken in account while in laminar

Chapter 2. General Principle of Electromagnetic Brakes 2.1. Introduction Electromagnetic brakes have been used as supplementary retardation equipment in addition to the regular friction brakes on heavy vehicles. We outline the general principles of regular brakes and several alternative retardation techniques in this section. The working principle and characteristics of electromagnetic brakes are then highlighted. 2.2. General Principle of Brake System The

experiment‚ the very first step is to weigh the plain block and object used on top of the wooden block in grams and Newton’s‚ as this information will be useful throughout the lab. Next place the ramp board horizontally on a table to measure the friction of the block and the weight of the soft drink can set on top of the wooden black by connecting the blocks hook to the spring scale. Meanwhile set the block and its weight on the board with its largest surfaces in contact with the surface of the board

energy at all points of the motion is equal. Even though the total amount of mechanical energy decreases over time‚ the other energy is not lost‚ but instead becomes thermal energy. This thermal energy is produced from friction‚ in the form of both air resistance‚ as well as internal friction within the spring. If a real vibrating spring suspended vertically undergoes damped harmonic motion‚ then the dampening of the spring will be slow‚ but is instead
