PhysCasts: Exploring Simple Harmonic Motion
(Swinburne Commons, 2013)
This PhysCast is about simple harmonic motion. A 0.12 kg body undergoes simple harmonic motion of amplitude 8.5 cm and a period of 0.20 s. (a) What is the magnitude of the maximum force acting on it? (b) If the oscillations ...
PhysCasts: Determining the Acceleration of a Cylinder Rolling Down a Slope
(Swinburne Commons, 2013)
In this PhysCast we are asked to consider the motion of a uniform cylinder of mass m and radius R as it rolls smoothly down a ramp at angle theta to the horizontal. We are asked to find an expression for the linear ...
PhysCasts: Energy Conservation in a Vertical Mass Spring System
(Swinburne Commons, 2013)
This PhysCast examines the question: we have a mass-less spring with k = 74 N/m and it is hanging from the ceiling.
PhysCasts: Calculating the Thermal Speed of Oxygen Gas
(Swinburne Commons, 2013)
In this PhysCast we are asked to find the average translational kinetic energy and the thermal speed of oxygen gas molecules.
PhysCasts: Damped Simple Harmonic Motion
(Swinburne Commons, 2013)
This PhysCast deals with simple harmonic motion where dampening is present. The amplitude of a lightly damped oscillator decreases by 3.0% during each cycle. a) What percentage of the mechanical energy is lost in each ...
PhysCasts: An Unknown Oscillation Frequency
(Swinburne Commons, 2013)
This PhysCast is about simple harmonic motion. Two springs are attached to a block which can oscillate on a frictionless floor. If the left spring is removed it oscillates at a frequency of 30 Hz. If instead the right ...
PhysCasts: Hydrostatic Equilibrium: Gauge Pressure?
(Swinburne Commons, 2013)
A fully loaded Volvo station wagon has a mass of 1950kg. If each of its four tires is inflated to a gauge pressure of 230kPa, what is the total tire area in contact with the road?
PhysCasts: Calculating Density and the Uncertainty in the Density
(Swinburne Commons, 2014)
This is a numerical error propagation example where we're asked to find the density and uncertainty in density of two objects.
PhysCasts: Center of Mass of Continuous Object Using Symmetry
(Swinburne Commons, 2013)
In this PhysCast we are asked to find the centre of mass of a hexagon with six equal sides of length a, but where one of the triangles is missing.
PhysCasts: A Fluid Problem Involving Hydrostatics and Hydrodynamics
(Swinburne Commons, 2013)
This question deals with both hydrostatics and hydrodynamics. A 4.0cm diameter horizontal pipe connects passes through a freshwater dam at a depth of 6.0 meters and is sealed by a plug. A) Find the magnitude of the frictional ...
