Investigation on the Velocity

Of a Block of Wood With

Various Weights On



My aim of this investigation is to find out the velocity of an object if we add different weights to it when we let it go down

My prediction for the investigation is that if you add any weights to the object the velocity of the object will not change rapidly, I predict this because everything falls at the same velocity no matter what it weighs. Unless one of the objects has a bigger air resistance that is pushing against it. I know that everything falls at the same velocity because I did some research on the Internet and other sources of information such as science books.                        

E.g. The apple and feather.

Fair Testing

I will make the investigation a fair test by: -

  • Letting the object roll or slide down the ramp and not force it by pushing it with my hands.
  • Keeping the light gates the same distance between each other
  • Keeping the ramp at the same angle for each test
  • Not deliberately inflicting friction upon the wooden block

Controlling the Variables

  • I will not change the distance between the light gates because it will let the block of wood slide down the ramp for a longer period of time causing the result to be odd and different from the rest of the recorded results.
  • I will not push the object down the ramp because it will give a high increase to the wooden block’s velocity. This will cause the block to reach the other light gate a lot quicker than it should do; this will cause the results to be odd and different from the rest of the recorded results.
  • I will not increase the angle of the ramp because it will cause the block of wood to slide down the ramp a lot quicker because the ramp’s angle is getting closer to the vertical drop which causes the velocity of the wooden block to increase.
  • I will not add deliberate friction on the wooden block by not putting anything on the wooden block or ramp, which will slow down the velocity of the block.

I think the reason for getting odd results is due to the friction of the block of wood rubbing against the side of the ramp.

The results I have are sufficient enough to come to a conclusion because of

“The best line of fit”that is drawn from the first result to the last result, from this information I can reach a conclusion.

Additional Experiment

To extend my investigation in this subject I could of looked at the velocity of the wooden block with deliberate friction added to the block of wood to see how much friction can reduce the velocity of the wooden block by comparing the results with the results I have now.

If this experiment was carried out I would have used sand paper that would of been stuck to the bottom of the block of wood to cause the deliberate friction between the wooden block and the ramp.

This experiment would have been good to see how friction effects our lives by looking at the good points of friction and the bad points of friction such as: -

  • Friction between the rubber tyre and road to help the car stay on the road and not slide of so we are safe from any danger.
  • Friction between the body of the car and the air resistance which causes the car to loose acceleration.
  • Friction in a cars piston engine which causes: -
  • Gears and cogs to ware out
  • Noise
  • Heat  
  • The engine to be lubricated at various times this costs money and time

    The usage of books means we can increase the height by any amount because some books are thicker than others are. We can get the height of the ramp at the start line almost exactly on the said measurement by simply moving the pile of books forwards or backwards fractionally.

  1. Investigate how the weight of an object affects the force required to overcome friction.

    However, if the force required to overcome friction is greater than the small-scale force meter will allow then it will be switched with the large-scale one. All of the results will then be tabulated. o All of the above will then be carried out a second and third time.

  2. An investigation to find out how different variables will effect the movement of a ...

    There are some variables which could greatly affect the outcome and the results of the experiment. * The surface of the desk that the wooden block slides on. * The numbers of elastic band used to fire the block. * The distance that the elastic band is pulled back.

  1. Investigation into Friction.

    This amount of added weight was recorded. It is the maximum amount of weight that can be added to the wooden block during the experiment for the smooth and the rough hardboard surfaces. 5. The results were recorded in Tables 1 and 2.

  2. Designing a children's slide, making it exciting for the children whilst exercising safety.

    Assumption: There will be no other factors that will affect friction, such as footprints or mud on the surface of the slide. This will increase friction and as a result decrease velocity, and hence the time of the journey.

    at which point the sum of the added weights shall be recorded (force needed to overcome the static friction). This will be repeated 2 times. Then, the surface the block of wood is being pulled over will be changed, and the mass of the block of wood will be altered by using weights.

  2. The experiment consisted of recording the results of a small toy car being allowed ...

    From this we can get the acceleration of the car down the ramp by dividing by the mass. Now we know this, we can actually find out how long the car would spend on the ramp, and how long it will take to fall to the ground using suvat equations.
