It keeps or converts kinetic energy into power, which it uses to charge the devices. Heat in the body can be of two forms: potential and kinetic energy Smith, Van Ness, Abott, 2001. The primary objective of the lab experiment to assess the conversion of the work into kinetic energy particularly works done by the underlying force of gravity. To what accuracy did you measure that angle in radians? Wood block: Any deformation in the shape of the wood block would affect the results of this lab. Place 1000g mass on top of wood block, and place wood block on desk. However, dθ is not also 0. The greater the mass is, the greater the static and kinetic frictional force is.

Pull from the spring scale at a constant velocity. The box does not move until the tension in the string is grates than the frictional force. On the other hand, a friction force is a type of force that acts on a moving body and it is always parallel to the motion of the object. To what accuracy did you measure that angle in radians? Thus, the work kinetic energy. Using a 1000g mass and a ramp, pull the wood block up the ramp at 3 different inclines. Works cited Shipman, James T.
Unequal encounter, heterogeneity, and diversity concept require careful handling. Other sources of errors were from the calibration of the sensor. Work, Energy, and Efficiency: Pulleys The objective of this experiment is: To explore the use of pulleys inmaking work easier. Conclusion: Both the frictional force and tension in the string are working in opposite direction. . Using a 1000g mass, repeat step 3 on different surfaces. Instead, it is energy in transit, transferring from one body into another.
Friction by Tsing Introduction Arguably, the book by Tsing stresses that globalization is a system that unites the world into asingle imperial system. It can also transmit from the system to its environment or vice versa. However, dθ is not also 0. The flow of information is critical in engaging the. To investigate the relationship between ideal mechanical advantage and number of stands supporting the mobile pulley.
Acceleration Coefficient of kinetic fricton. Factors affecting the rate of a chemical reaction — The kinetics of a Thiosulfate Solution Introduction: Various approaches are used to study the kinetics of reactions. In order to slide the box with a constant velocity, a force equivalent to the force of kinetic friction must be applied. An observational error example would be if the experimenter did not read the thermometer correctly when recording results. Some possible sources of errors in the lab includes instrumental or observational errors. In order to eliminate all the expected errors, it is necessary to clean both the sliding surfaces. In general, this coefficient is less than that for static friction.
Heat is also like work. Repeat the process for each of the two wide surfaces of the friction block being in contact with the track. Instrumental errors can occur when the tools are not functioning exactly as they should be. You seem not to understand the meaning of the symbols in the expression you are plugging in. The inconsistencies in the surface would cause different readings for the forces depending on how rough or smooth it was. You seem not to understand the meaning of the symbols in the expression you are plugging in. Download file to see previous pages Static friction is denoted as Fstatic.
Friction: Finding the coefficient of kinetic friction. What factors affect kinetic friction? Friction Lab - The Physics Aviary Friction Lab. For example, the spring scales giving inaccurate data due to the fact that they are previously well-used. So this way, it's even more apparent that the coefficients of friction both static and kinetic don't change with weight or mass. Each of the boxes as well as the table should be cleaned thoroughly before the experiment.
One reason is because the kinetic friction coefficient is lower than the static friction coefficient. So that kinda makes sense. Lab 4: Friction Friction: Determination of µs and µk Interaction of two bodies on the surface always involves contact forces. Keep your laboratory diary and how to write up your end-of-term reports;. The graph below the action is a graph of the tension in the string. Repeat step 3 using 3 different masses on one surface. It is different from the ordinary portable charging devices because it does not require electricity to charge it.
