Slipping and sliding Physic Investigation

Slipping and sliding


As part of our Physics coursework we were asked to investigate the force required to pull a piece of wood whilst increasing the weight on top of it using a Newton meter and some weights. We were provided with the appropriate apparatus and given the necessary instructions from our teacher.

         The objective of our experiment was to obtain a set of results from which we would be able to understand the relationship between force and mass and the effect of variables.


Statement: ‘The greater the mass of the wood, the greater the force required to move the wood.’ This is because increasing the mass will increase the friction between the wood and the table.

6. 1 piece of wood

7. 1 nail or hook

All these things are shown in the diagram below;


1. Place the masses on top of the piece of wood and place the wood on a flat surface;

2. Attach the string onto the Newton metre and fix the hook on the end of the wood;

3. Give a controlled tug on the Newton metre. The measurement scale will move. Carefully observe the measurement scale. Record the pulling force displayed on the scale when the wood starts to move steadily and stop pulling.

4. Add the required masses to the shoe and repeat.

5. carefully note down the forces given.  

Results Of The Preliminary Experiment

the experiment went quite well but I could have improved it in some ways.

hich may make the experiment fairer;

Constant Variables;

         To make this experiment a fair test the following variables must be kept constant throughout the experiment.

Ø                       Area of wood in contact with surface

Ø                  The slope of surface

Ø                  The length of string

Ø                  Type of surface under wood

Ø                  Thickness of wood

Ø                  Size of piece of wood

Safety Procedures

(i) Make sure the weights are firmly on the wood so it is not possible for the weights to fall out and cause damage to the surroundings.

(ii) Place the wood in the middle of the table to prevent it from falling off.

(iii) Do not force too many weights on the wood as they may damage the wood or fall out.

    This is because they have extraordinary results within them. The graph curves because of the above formula. If the force doubles and the distance pulled back doubles then the elastic band stores four times as much potential energy and fires the weight four times further.

    Each test will be done 5 times then averaged. To make sure it is a fair test I will: unless it breaks use the same Newton meter, I will use the same block and the same side of the block every time, I will use the same substance/type of substance

    Once I had placed all my timings in the table I was to work out the average of each set of timings. To do this I was to add up all of the sets of timings together and then divide it by 5 because that was the number of times I had done the experiment for each set.

Where "v" is the velocity of the body and "R" is the radius of the circle travelled. To calculate the velocity a body is travelling, use energy relationships to solve for the kinetic energy and the associated velocity.

    The balance of weight must be equal over the surface of the object travelling down the slide. This will reduce any frictional forces present as one particular area will not slow the object more than another, thus equalising any frictional forces present.
