Physics Lab Report Centripetal Force

Centripetal force F is the net force causing the centripetal acceleration of an object performing uniform circular motion. Its magnitude is given by the equation: F = Mrs. When an object is whirled in horizontal circular motion in mid-air with a piece of string (as shown in figure 1 above), the centripetal force on the …

So, the total work done is actually equal to the gravitational potential energy. In the result, it is obviously seen that high percentage error is calculated. It is because there are many ways of committing a mistake in this part. Some of these factors are assuring the angle and the height and applying an extremely …

Specific heat is defined as the amount of energy necessary to produce a temperature change of 1 co per gram of substance. The specific heats of different substances vary, and therefore this quantity may be useful in identifying an unknown. The measurement of heat changes is called calorimeter. In this lab activity, calorimeter will be …

Also the total amount of energy in a closed system never changes. Along with my wonderful partner Kelvin e thought that energy in a closed system will remain constant throughout unless there is an outside energy such as “work” or friction. We also discussed the differences and similarities between closed and open systems. We wanted …
