Friction is a form of force that hinders the acceleration of objects Simply put , friction is a negative force that helps an object to stop or reach zero acceleration . In the following experiment , friction is analyzed with regards to differences in mass and how such differences affect the movement of such objects

Friction is defined as , Friction is the resistive force acting between bodies that tends to oppose and damp out motion . Friction is usually distinguished as being either static friction (the frictional force opposing placing a body [banner_entry_middle]

at rest into motion ) and kinetic friction (the frictional force tending to slow a body in motion . In general static friction is greater than kinetic friction (Blau , 1996

In the given situation , an individual is asked to roll down two balls down the ramp . One ball is significantly smaller and lighter than the other . The velocity and time are measured as the ball travels down the ramp . The experiment requires that the time it takes for each ball to reach the bottom of the ramp to be recorded . Such action is to be performed and multiple times are to be recorded . The differences between the times are to be analyzed in to prove or disprove the hypothesis stated for this experiment


The problem that this experiment aims to resolve is stated as follows

How does mass affect friction


To answer the problem stated above , the following hypothesis will be proven or disproven

Mass causes a greater amount of friction . More massive objects create greater amounts of friction , thus lead to a lesser velocity and acceleration

The independent variable in the experiment is the mass of the object The dependent variable is the time it takes for the ball to travel down the ramp

Materials and Procedure

Using a ramp with a height of 1 meter and a length of 2 meters , two balls of the same material with mass 1 kg and 0 .5 kg were rolled down the ramp . The ramp was conducted by stacking books one on top of the other until the desired height was reached . A used to achieve the desired height of 2 meters

Once the ramp was constructed , each ball was rolled down the ramp 5 times and the time was measured in each occasion . The recorded times are discussed in the following section . Analysis was then conducted to determine how the difference in mass affects the time it takes for each ball to roll down the ramp


In each of the five times the experiment was conducted , the ball with a greater mass took longer to travel down the ramp . It must be noted that each time the procedure was done , the same angle for the ramp and the same ramp was utilized . What this means is that the difference in times should not be attributed to the ramp but to the mass difference between the two balls

Analysis and Conclusion

The results of the experiment can only lead… [banner_entry_footer]
