Properties of Footwear - Friction is a force.

Introduction

Properties of Footwear

Friction is a force. This force is when one surface slides and rubs across another and this causes friction and this tries to stop the movement of the two surfaces moving. Friction opposes the movement of an object this is noticeable when a ball is moving through the air and the air resistance is slowing the ball down until it eventually comes to a halt. This type of friction is called Kinetic (which means moving) energy into heat.

Examples of Friction

Running – especially when you start running pushing your feet against the ground is causing friction so that you can move forwards. Sprinter Runners have to wear spikes on the bottom of their shoes so that they can improve their grip on the running track.

Examples of Sports where low friction is good

Ice Skating – Skates are designed to make you go faster. On the front of the skate there is a spiky front where this is designed to help you push off from a standing start.

Skiing – AS the skies slide over the snow the ski poles are the only grip that you have as there is less friction on the snow.

Curling – Ice is brushed forwards and backwards to allow the stone to move faster to get to its destination

Examples of Surfaces that are likely to need friction

Rough surfaces such as Glass paper have a interlocking grip and this is a very strong grip.

Dry Surfaces are not lubricated and the chalk dries and roughens grip.

Un streamlined

Discussion of Vocational Implications

I have found that manufacturers should create different types of shoes for different types of sports. Such as a football boot should not be used for rugby because it is not such a physical sport and therefore they need less grip. Where as a rugby player needs bigger studs in his boot because when he goes to do a scrum he will need this strong amount of grip from his studs to drive forwards to win the scrum.

  1. Squash Ball and Temperature Investigation

    is clear that as the temperature is increased, the bounce of the ball also increases proving the first part of my prediction to be right. This can be supported the Kinetic Theory as it deals with molecules vibrating and breaking their bonds as they receive more energy.

  2. Investigation into the range of a ski jump

    The range measuring ruler must measure from the point the ball leaves the ramp, which in this case is the edge of the table. This means that it must be accurately aligned under the table, this can be achieved using a plumb line.

  1. Investigation into Friction.

    Variables Independent variables: this will be R, the force acting on the two surfaces, providing frictional force. Using different values of mass, placed on the wooden block, will vary this. The other independent variable that will be changed in this experiment will be the bottom surface.

  2. Investigating the amazingness of theBouncing Ball!

    will obviouly be a lot higher. This can be predicted due to the fact that the In H/H0 will reach the value of -2.66 at the first bounce producing a very steep line and so a much larger gradient and hence a much larger decay constant.

  1. Mechanical Properties of a Meter Rule

    The strain is an increasing. When a forces act toward the ends or a direct push, the stress is a compressive stress. The strain is a decreasing. These stresses may act together, producing compound stresses, as in flexure. When a bow is bent there is a compression of the fibres

  2. Liquid Friction.

    As long as laminar or streamline flow exists then, the stress exerted on the liquid is directly proportional to the velocity gradient that causes it. Viscosity can be expressed in (known as the Poiseuille (PI) or Poise (P)). Different shapes moving through a liquid will distort the measurement of viscosity

  1. report on glass

    Commercial production of sheet glass using the Fourcault process eventually got under way in 1914. Also at the end of World War 1 Emil Bicheroux developed a process where the molten glass was poured from a pot through two rollers this made the glass a more even thickness and less time spent grinding and polishing.

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

    The small-scale meter is more accurate than the large-scale one because you can read off a more accurate result as the values only increase by a small amount each time. o The force meter will then be pulled slowly while watching it.
