Assessed Experiment on the Efficiency of a Ramp
Planning
========
I am investigating the efficiency of a ramp depending on the mass of
the load , the height of the ramp or the angle. I have chosen the
amount of load to be lifted up the ramp because I think I can get a
more accurate set of results this way. The ramp is a basic but very
effective way of moving objects to a greater height more easily than
simply lifting.
Fair Test
· I will take all of my results on the same day with the same
equipment and area.
· I will repeat my test three times for a more accurate test.
· I will pull the bucket along at the roughly same steady speed every
time.
· I will take the results myself so they will not differ.
A fair test is important in all investigations because otherwise the
results will not be reliable. A fair test should avoid being biased
and enable repeatability.
Prediction
The variable that I have chosen is the increase in masses and
therefore weight to the bucket. I would predict that as the mass
increases the force required to achieve a constant speed will also
increase. As the mass is increased the friction between the bucket and
the ramp increases. Gravity is a constant force on all masses the
incline is the same for each increase in mass. To overcome the
resistance of the inclined surface the force is greater for larger
masses.
If all things are equal that is gravity, the incline and speed. Then I
predict that for each doubling of the mass the force will have to
double.
Techniques and Safety considerations
· I will mark the ramp with a distinctive line to keep it inline with
desk in case it slips. This is to get more reliable results.
· To make sure the ramp does not slip I could put a door stop or wedge
in place.
Since there are so many options on the market, take several options in consideration and choose the best one according to you specific requirements. Gather all information, so you can compare in-floor with fold-out ramps and choose one according to the conditions you will be using it. If you're based in an area where it rains and snows a lot, an in-floor lift may be solution to helping you keep your interior clean. Fold-out lift may be a better option if you live in area with lots of curbs and hills.
The purpose of the projectile lab is to test the validity of the law of conservation of energy. The application of this law to our everyday lives is a surprisingly complicated process. Conservation of energy states that energy cannot be created or destroyed, but that it can be transferred from one form to another. Consider the projectile lab from document A that this essay is based upon. In an ideal experiment, the projectile is isolated from everything except the gravitational field. In this case, the only force acting on the particle is gravity and there are only two forms of energy that are of interest: the energy of the particle due to its motion (defined as kinetic
Then the. 1. What is the difference between a. Set out equipment as shown in the diagram. 2. What is the difference between a.. Ensure the height at the start line (the summit of the ramp) is.
Investigating the Efficiency of Different Pulley Setups. Aim In this experiment I will be investigating the efficiency of five different pulley setups. These are the results shown below. Background on pulleys A pulley is one of the simplest mechanical powers or machines consisting of a grooved wheel/roller(s) for a cord or string to pass over a mounted block this is used for lifting a mass or changing direction of power.
* I will then use a small pile of books and set the ramp up at the

Step-Stair Investigation For my GCSE Maths coursework I was asked to investigate the relationship between the stair total and the position of the stair shape on the grid. Secondly I was asked to investigate the relationship further between the stair totals and the other step stairs on other number grids. The number grid below has two examples of 3-step stairs. I will use Algebra as a way to find the relationship between the stair total and the position of the stair on the grid.
· When I have collected my results I will place them in a table like
I must stress that is it of extreme importance to adhere to the class note guidelines set out by Lowry (2014) who states that “when viewing the person as a load, consider the following; weight, height and mobility”. I also believe that it is important to ensure that mechanical equipment such as trolleys and hoists are in excellent working condition. When taking these last two points into consideration the risk of injury should be greatly reduced.
The independent variables in this experiment are the height of the ramp, the length of the ramp, the surface of the ramp, the weight of the marble, the size of the marble, and the surface of the marble. The dependent variable is the distance the ball rolls. The controlled variables are the starting position of the ball, the angle of the ramp, and the surface of the floor. Units: The height of the ball from the ground, the height of the ramp, and the distance the ball rolls will be measured in centimeters (cm).

An outdoor climbing route, as opposed to an indoor one, is largely ambiguous. An indoor route is often color-coded and tells the climber where they should grab and hold. By the nature of being outdoors, climbing on a rock face uses adaptive movement, has to be more ...
