Abstract: What could the force of kinetic friction depend on? Theory
... Click and drag to get the region of interest and use the STAT button to get the mean. You don’t need to print out any LoggerPro graphs. Record your kinetic friction data in the following table in Excel! Do at least 7 trials, with 7 different added masses. Choose a good range of added masses! Go up b ...

Placing Charges Conceptual Question
... The two forces acting on charge 2 correspond to the forces exerted on it by charge 1 and charge 3. This means that one of these forces must pair with a force on charge 1 of equal magnitude and opposite direction and the other must pair with a force on charge 3 of equal magnitude and opposite directi ...

Lecture 7: Rotational Motion and the Law of Gravity
... • An object can have a centripetal acceleration only if some external force acts on it. • An example is a ball whirling in a circle at the end of a string. In this case the tension in the string is the force that creates the centripetal force. Net centripetal force Fc is the sum of the radial compon ...

Kinematics Multiples
... Although the speed varies linearly with time, KE is the square of the speed, so it should be a parabola, which rules out graph B. In graph D the PE is decreasing quickly at first and then more slowly while in graph A the PE is decreasing slowly then quickly. Since the ball speeds up as it approaches ...
