Work = Force distance (the force must be parallel to movement) OR Work = (Force)(cos )(distance) When you are determining the force parallel to the movement you can do this manually and keep track of the direction of movement or you can use the gener

Position, Time and Displacement
We begin our study of motion by considering objects which are very small in comparison to the size of their movement through space. When we can deal with an obje
Uncertainty Propagation
Addition and Subtraction
For any combination of addition or subtraction, the absolute error in the result is equal to the sum of the absolute uncertainties of the parts. If F = A B + C + D , then F = A + B + C + D .

Guidelines for a Physics Lab Reports
A laboratory report has three main functions: (1) To provide a record of the experiments and raw data included in the report, (2) To provide sufficient information to reproduce or extend the data, and (3) To analyze th
