Friction - Lab Report Example
It is widely believed that the natural state of an object is when it is at rest. Forces are responsible for the movement of a body. To test Newton’s law, various experiments can be conducted on the acceleration and proportionality of an object…
A proof of an increase or decrease in mass of the Newton’s experiment is determined by the force and acceleration achieved from the experiment.
The goal of the experiment is to verify the existence of Newton’s second law by finding the coefficient of static friction, µs and the coefficient of kinetic friction, µk. using the experiment stated below.
Have you wondered the make-ups of mechanics? Well Newton’s second law breaks it down into simple understandable terms by providing a means of translating directly between the acceleration and force acting towards a given mass or object.
The experiments are based on the concepts of force and Newton’s Laws of Motion, particularly Newton’s Second Law which states that: the acceleration of a body is directly proportional to the net force acting on the body, and inversely proportional to the mass of the body. From this definition, the equation Net Force = Mass x Acceleration (Fnet = mass x acceleration) is derived. Air tracks were used to reduce friction; the little amount of friction that remains in the system is negligible in the data. The suspended mass was subject to gravity which has a constant acceleration of -9.81 m/s2. The variables were solved to include: acceleration of the sled, velocities of the sled at each photo-gate, net force acting on the string, and the time taken from release to the first photo-gate and between the photo-gates. Acceleration was calculated using the formula: Acceleration= Velocity/ Time. The experiment is commonly used in mechanics fields to determine the acceleration acting towards a given mass or object.
