Friction Investigation Physics Coursework

Extracts from this document...


Sophie Vernon 10a Friction Investigation physics Coursework Which Experiment I have chosen: My group Hannah, Keely and Jenny decided to do the experiment using different weights and then calculating its friction by the distance the weight travelled when flung from an elastic band. Was it a fair test? Yes. It was a fair test because all the other factors in the experiment stayed the same except for the weight, which increased. ...read more.


Also we had to make sure that the surface of the floor or table we were using always stayed the same and that we did not move, this was also to ensure the experiment was safe because the smoothness of the surface will affect the friction that occurs. Safety: We had to make sure that safety was a priority we did this by ensuring we always wore safety goggles and behaving in a sensible manner with the elastic bands. ...read more.

This means that the heavier the weight the more friction it will create as the force it has on the surface is stronger.

  1. How does the weight of an object affect the friction it has on the ...

    of sand paper 18 036C, m = 6/1000 m = 0.006 In my prediction, I predicted that as the weight of the block of wood increases, so would the force needed to overcome its static friction and move it. I therefore did some more background research, and discovered the term coefficients of friction.

  2. This investigation is about what factors affect friction.

    rough, there will be a bigger grip of the tyres and the road; therefore there will be more friction. If the surface of car tyres has wearied away then there will be a smaller grip of the tyres and the road; therefore there will be less friction.

  1. Investigation into Friction.

    This means that we will need to determine the maximum mass that can be added to the wooden block so that the force meter is capable of applying enough force to make the two surfaces slide. This will need to be done with both the rough and the smooth hardboard.

  2. Liquid Friction.

    In a liquid, viscosity is determined by the strength of the bonds between its molecules, something which temperature will effect. As temperature increases a liquid will become less viscous as its bonds become weaker and start to break more easily.

    As been as the terminal speed is what speed an object is falling down at and all through an objects decent it is speeding up (untill it reaches it's terminal speed), the quicker the terminal speed is reached, the slower the object will desend.

    Another thing I will need to find is the best meter, one which gives the most accurate reading, is easy to read and doesn't keep fluctuating. Also I need to find the correct voltage, this is so that the wire doesn't heat up, as this will heat up the wire

    This equation is only effective for masses of 300g and above, as smaller masses have little impact on the spring and do not extend at a constant rate. This equation determines the minimum extensions and the forces required. F=k+ c F= 2.94N K= 9.74Nm�� = 8.4cm�0.084m c=?

  2. Pendulum Coursework.

    I believe that there is positive correlation between time and length of the pendulum. The longer the length of the thread the longer the time period of the pendulum. I can say this because if the string is longer, it will have to travel a greater distance, so the time
