Forces and Friction

Introduction:

Friction is a very common force. Whenever one object tries to slide over another object friction tries to stop it. Static friction is a bigger force than dynamic friction.

Aim:

My aim is to investigate how much force is needed for a box to be moved on different surfaces and when added more weight to the box. I will be investigating the friction force on the surfaces. The key thing that I have to consider whilst investigating is A) the ground surface it is on and B) the weight that is put in the object by doing this I will acquire my results.

Prediction:

I predict that if the box is on a smooth surface with fewer weights within the box, the box will move instantly as there would be less friction occupied. As the surface is smooth the box will not need as much force to pull it as there is less gravity pushing down on the box. On the other hand I predict the box will need far more force to pull the box if it had more weight inside the box with a rougher surface. The more gravity force on the box the more friction will be necessary also when the surface area will be forceful.

Hypothesis:

Conclusion

By putting my scientific knowledge at the use I have come up to a conclusion that there are usually forces acting on an object. The forces might change the shape of the object or even change the direction it is moving in, it may also slow down the moving abject. The build up of static I caused by friction. The friction force that we consider a result from contact between two surfaces. It then follows that if there is a friction force then there must be force of contact between the two surfaces this means that there must be a normal force as well.

    For experiment 1: * I will make sure the horizontal ruler is straight and not bent as this would cause readings to be read incorrectly. * That the weights are added on the middle of the rule. * To make sure that I do not move when I am taking

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

    That will be the value found for the dynamic friction for that particular weight. o Then the block of wood with the force meter attached to it will be placed back at the start of the sand paper. A 100g weight will then be placed on top of the wood

  1. Investigation into Friction.

    A force meter that can measure up to 30 N will be used, for safety's sake. The reading on the force meter will be taken the moment that the blocks start to slide over one another, so that the force needed to overcome friction is recorded.

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

    But the amount the acceleration change will be depend upon the magnitude of the force applied, the greater the force, the greater the acceleration will increase by. Friction plays an important factor in acceleration and is defined as the resistance an object encounters in moving over another.

    The frictional force F for a particular surface is not constant. It increases as the applied force P increases until the force F reaches a value F maximum beyond which it cannot increase. The object is then just about to move and is said to be in a state of limiting equilibrium.

    to the friction of the shoes on the pavement, this is why lubricating oils are used to fill in the gaps between moving machinery parts. There are three main kinds of friction: Sliding or kinetic friction; this is produced when two surfaces slide across each other, like when a book moves across a table.
