Dynamics Extension – Part II
Physics 12
Learning Outcome (Student will…):
use vector analysis in two �dimensions for systems involving two or more masses, relative motions, static equilibrium, and static torques
Relative MotionRelative MotionDefinition: Reference Frame – a
coordinate system in which an experimenter makes position and time measurements of physical events
Definition: Inertial Reference Frame – that in which the Laws of Motion apply (not accelerating)
How do we analyze motion in two different reference frames?
Atwood’s Machine Atwood’s Machine (simple)(simple)
Example of Modified Example of Modified Atwood’s MachineAtwood’s MachineA 15 kg cart is attached to a hanging 25
kg mass. Friction is negligible. What is the acceleration of the 15 kg cart?
Inclined PlanesInclined Planes
What is the acceleration of the system? What is the tension developed in the connector?
