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.

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.

Conclusion

Method

First of all I place the ramp on the desk and gather my equipment, masses, bucket and Newton Metre. I attach the Newton metre to the bucket using string and then place it at the bottom of the ramp. I pull the empty bucket up the ramp a constant steady speed and repeat this three times and then place the next mass into the bucket. I pull the bucket up the ramp 1.5m up the ramp and then record the results in a table.

    All the same apparatus will be used throughout the experiment; bar the Ticker Tape as it cannot be reused; this is to ensure all conditions are the same all the way through the experiment. All the apparatus should be independently tested to ensure accuracy and good working order.

  2. Factors affecting the speed of a trolley Travelling down a ramp.

    Kinetic energy is a scalar quantity; it does not have a direction. Unlike velocity, acceleration, and momentum, the kinetic energy of an object is completely described by magnitude alone. Also friction is another factor that affects the speed of a trolley travelling down the ramp.

    Also it depends on the pull of gravity and the speed as if the gravitational pull is even a tiny bit bigger than the speed it will slow the tube down drastically. I predict that my results graph will look similar to this, because as I have told you numerous

    Until limiting static friction () was reached, the block began to slide and the reading (representing ) remained basically constant. Experimental value of is much smaller than .

    Best of all, I thought, if I could model the situation but ignore the effect of turbulent water, I could look at the mechanics of the propeller, and then compare the theory with what happens in real life. It seemed like a good mix of fresh ideas and traditional physics problems.

    However, what it does show is satisfactory enough to make a calculated prediction for the experiment. > Hypothesis: my prediction in its most simple form is that in the experiment, the general trend of the results is that when y is big, x is smaller, and when y is small, x is bigger.

    He modified their concepts and ideas into his own constructs. His laws of motion corrected the discoveries of Galileus Galileus (the English xenoym is Galileo Galilei), using deduction and fluxions (The Calculus). Galileus did not include the object's initial motion "u.t" when he wrote the distance equation s = 1/2 at 2.
