PhysCasts: 2D Motion: Washout!
Hall, B. (Brenton) (Swinburne Commons, 2014)This is a PhysCast on 2 dimensional motion. A raging flood has washed away a section of highway, creating a gash 1.7 meters deep. A car moving at 31 m/s goes straight over the edge. How far from the edge of the washout ...

PhysCasts: A Camper Hangs a Pack
Hall, B. (Brenton) (Swinburne Commons, 2013)In this PhysCast a camper hangs a 26 kg pack between two trees using separate roles of different lengths. Find the tension in each rope.

PhysCasts: A Fluid Problem Involving Hydrostatics and Hydrodynamics
Hall, B. (Brenton) (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 ...

PhysCasts: A Gas Expands with a Constant Temperature
Hall, B. (Brenton) (Swinburne Commons, 2013)This PhysCast is about thermodynamic processes. One mole of oxygen (assume it to be an ideal gas) expands at a constant temperature of 310 K from an initial volume V1 = 12 L to a final volume V1 = 19 L. How much is done ...

PhysCasts: A Hot Horsehoe
Hall, B. (Brenton) (Swinburne Commons, 2013)In this PhysCast we are told that a horseshoe has a surface are of 50cm2 and a blacksmith heats this to a red hot 810 degrees C. What rate does it radiate energy?

PhysCasts: A Suspended Nonuniform Bar
Hall, B. (Brenton) (Swinburne Commons, 2013)The following PhysCast deals with a nonuniform bar which is suspended and in static equilibrium. A nonuniform bar is suspended at rest in a horizontal position by two massless cords. One cord makes the angle theta = 36.9 ...

PhysCasts: Accelerating Merry Go Round
Hall, B. (Brenton) (Swinburne Commons, 2013)This PhysCast deals with rotational motion. A merrygoround rotates from rest with an angular acceleration of 1.50 rad/s2. How long does it take to total through the (a) first 2.00 rev and (b) the next 2.00 rev?

PhysCasts: Acceleration of an Ice Puck
Hall, B. (Brenton) (Swinburne Commons, 2014)A 0.20 kg puck upon a frictionless ice surface is acted on by the forces shown in the diagrams. Find the resulting accelerations?

PhysCasts: An Unknown Oscillation Frequency
Hall, B. (Brenton) (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: Analyzing Laboratory Data
Hall, B. (Brenton) (Swinburne Commons, 2014)This PhysCast focuses on the laboratory analysis techniques that you are required to use in energy and motion in the 5 labs.

PhysCasts: Calculating Density and the Uncertainty in the Density
Hall, B. (Brenton) (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: Calculating the Thermal Speed of Oxygen Gas
Hall, B. (Brenton) (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: Calorimetry with Ice Water Mixture
Hall, B. (Brenton) (Swinburne Commons, 2013)In this question a 50 g ice cube is dropped into 200 g of water in a thermally insulating container. If the water is initially at 25 degrees C and the ice comes from the freezer at 15 degrees C, what is the equilibrium ...

PhysCasts: Calorimetry with SteamIce Mixture
Hall, B. (Brenton) (Swinburne Commons, 2013)In this question we are asked what mass of steam at 100 degrees C must be mixed with 150 g of ice at its melting point in a thermally insulating container to produce water at 50 degrees C?
