Dissipative forces Study guides, Class notes & Summaries

1. A decrease in the temperature of a gas sample in a closed container will always result in an increase in the: A. value of the PV / (RT) ratio. kinetic energy of individual gas molecules. C. gas pressure on the container. D. attraction between gas molecules. Correct Explanation: D. Since the temperature of a gas is proportional to the average kinetic energy of its molecules, decreasing the temperature will result in a decrease in kinetic energy. This decrease in kinetic energy will ...

Dissipative Forces Physics Notes

IB-Physics-Core-Notes Topic 2 Mechanics 2.1 Kinematics 2.1.1 Define displacement, velocity, speed and acceleration. Displacement- Defined as the change in position of an object. Displacement is a quantity that has both direction and magnitude, it is a vector. Measured in metres. Speed- How far an object travels in a given time. Rate of change of distance (ms-1) Velocity- The vector version of speed. Tells us the magnitude of how fast an object is moving and the direction in wh...
