Could you run 0.8 kilometres in one minute?
The fastest 100m sprint speed record is held by Usain Bolt , reaching the speed of 43.94 kph. 0.8 km is 800 meters. For you to run 800 meters in 1 minute you would need to reach the speed of Usain bolt speed: 43.94 x 800m= 35152 m/s. Though human endurance comes into play as well, as a person cannot run their top speed for more than 8 seconds. Usain Bolt was able to keep 95% of his top speed for 8 seconds during his…
Rene Descartes as a famous philosopher, mathematician and scientist in seventieth century has introduced a new method for recognising and distinguishing truth from untruth. Descartes believed that this method could be useful for every body since reason is same for all people. The aim of this essay is to demonstrate Descartes’ method in three parts. In the first part it will explain that what Descartes’ method is. In the second part, it will explain the philosophical meaning of this method. And…
Research: According to Newton 's Second law when force is increased acceleration increases assuming that mass stays constant. a=F/m
Purpose: The purpose of this lab is to prove when force increases acceleration also increases. The independent variable is amount of force applied to the Lenny Board and the dependant variable is the acceleration of the Lenny Board. 3 controlled variables are mass, surface of testing, and the Lenny Board (the weight, the amount of grease on the bearings, ECT) itself…
It begins with a couple of pedal strokes. Round and Round the wheels turn and your off like a shot. Sounds straightforward? Traveling across rural scenery. I love it. Edinburgh should be called the Happy Trails city once you get away out of the city there are a million of places to run, walk, hike or bike. I go mountain biking every Monday night with the club.
For the first 5 minutes my muscles burn, it feels like I am dragging myself through mud and being stewed alive all at the same time. Then…
Imagine that you are in a world where you can control everything. Flying, apparition, transforming into any form, deciding what happen next, massacre or resurrecting, all these things can be done simply by idiodynamics . Is it a world far from reality? In fact, some people could spend nearly one third of a day in such a world which is called lucid dreams. In a lucid dream, dreamers are aware that they are dreaming and then, if they are skilled enough, control the dream. Lucid dream is a vital…
Figure (4.2): Failure pattern of cylinder specimen (CY1).
Under pure axial compression loading for cube specimen (C1), the failure cracks generated are approximately parallel to the direction of load as shown in figure (4.3) with some cracks formed at an angle to the applied load. As a result, lateral shearing stress is produced in the cube specimen. The effect of this shear decrease towards the center of cubes; so these sides of the cube have near vertical cracks at the cube center.…
Sporting code of choice is Netball
Netball is a sport played with a ball and two teams of seven players. Netball games are played on a rectangular court surface with two raised goal posts with rings on the top. The rings are used to shoot the ball in. Each player has a specific position to play on the court and certain players are restricted to a certain place. Each team has a Goal Shooter, Goal Attack, Wing Attack, Centre, Wing Defence, Goal Defence and Goal Keeper.
In this experiment the main goal is to examine the correlation between position, velocity, time, and acceleration of objects, moving in one or two dimensions. Each and every experiment will be conducted under different conditions. For example, the first experiment requires a constant force (gravity) to act on the object, the picket fence. This experiments other condition is that we neglect friction. This object should be in nearly ideally circumstances. In the second experiment, the conditions…
At the end of this topic, you will be able to understand about:
Brakes are classified into six types based on the nature of power employed. Brakes are employed to stop the vehicle in the least possible distance.
The following media (Brakes) explains about the functions and types of brakes.
In this media, you will learn about ‘Brakes’.
Brake is one of the vital control parts of a vehicle.
Brakes are needed to stop the vehicle in…

Pendulum and spring
In this lab, two systems namely a pendulum and a spring that exhibit simple harmonic motion were studied. The systems were subjected to a mass of known weight and allowed to oscillate. Afterwards, the period of each was determined. In addition, the harmonic properties in the systems and their limiting factors were determined through quantitative calculations.
Any system that exhibits back and…
