Figure 1 below shows the change in magnitude of the steady state acceleration with time. This graph complies with Newton’s second law as the force applied is equal to 1 and the mass remains constant so and an acceleration of one is expected. I also tested this by changing the value of the force applied‚ to a value of 2‚ which in theory should give and equivalent change in the acceleration‚ to a value of 2. From Newton’s second law: it can be seen that as the force varies‚ provided moment of inertia

An investigation to find out whether the mass of an object attached to the bottom of a paper helicopter affects the time it takes to travel a fixed distance Aim: Does the mass of an object affect the time it takes to travel a fixed distance? Introduction: This is an experiment to find out the relationships between mass‚ distance‚ velocity and time. Dependent Variable: The height where the helicopter is dropped from. Independent Variable: The velocity of the helicopter‚ the time it takes for

Both laminar and turbulent flow regimes are to be studied. Equipment: Air valve Water manometer Mercury U-tube Isolating tap meter From water supply Needle valve Test tube Figure 1 Pipe friction apparatus A. Laminar Flow The laminar pipe friction apparatus is shown above. It consists of a water loop. The

This egg drop experiment forced me to think and develop a design that I felt confident with. I developed several models and tested them numerous times‚ but could not settle on one. Eventually‚ I was able to put an addition onto one of my designs which gave me confidence in its ability to protect that precious egg. I will explain why my design worked so well in respect to impulse‚ air resistance‚ and stability. First‚ I will discuss impulse. Impulse is a force acting briefly on a body and producing

Pressure Distribution around a Symmetric Aerofoil Abstract: The following report is based on an experiment conducted to calculate the lift curve slope for a symmetrical aerofoil subjected to varying angles of attack. Pressure readings were taken at different points on the upper and lower surface of the aerofoil. The report concludes that maximum lift is generated between 12 º -15º‚ which is also the stall point. It also states that region close to the leading edge contributes most to the lift force

\subsection{Survey of Existing Approaches} \label{ssec:existing} Because few remote control (RC) setups allow for live telemetry‚ almost all flying is done "by eye‚" and RC instrumentation and data logging is a poorly developed field. RC gliders especially eschew any projecting elements which could increase drag. The few relevant RC systems the author has found are described in this section‚ but most considered designs are in practice found only on manned vehicles. \begin{figure}[!htb]

Prac Report – Investigating Parachutes Experiment Aim: To measure how the size of a parachute t’s surface area affects the parachute’s speed‚ acceleration and time of flight. Hypothesis: A parachute with a larger surface area would fall slower due to that fact there would be a higher level of drag‚ or in other words more air resistance. Materials: * Sturdy garbage bags * Metric ruler * Scissors * Washers * Twist ties * Light-weight string * Stopwatch Method:

The advantages and disadvantages of travelling by airplane As well as being very exciting‚ airplane travel really can be one of the most efficient ways to travel around the world. The availability of cheap air travel means that it is now easy for almost anyone to fly anywhere. We will now look at the advantages and disadvantages of air travel. The Pros of Travelling by Airplane. Nobody can doubt the fact that our lives have been changed by air travel. It is much faster to travel by plane; it is
