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.

  2. Parachute Investigation

    At this point, the net force is 0 Newtons, and the parachute stops accelerating. Then the parachute will have reached its terminal velocity and it will continue to fall at a constant speed until intercepted by a solid object, such as the ground.

  1. The physics involved with a rollercoaster.

    Since the car is not accelerating vertically, the normal force is balanced with the gravity force which means they are equal. The surface of the track applies the normal force. According to the Newton's 2nd law, when an object accelerates, there must be an unbalanced force.

  2. Serving Newton

    There was no one available to teach Newton how to use these methods and equally, there was no-one who could correct or confirm his work. Newton sourced much theory from the works of others and when they seemed true, accepted such mistakes as well.

    If the mass is very close to critical, say k=0.99, then each spontaneous fission neutron will create a chain that lasts 100 generations. This persistence of neutrons in subcritical masses further reduces the time window for assembly, and requires that the reactivity of the mass be increased from a value
