• #### PhysCasts: 2D Motion: Washout! ﻿

(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 ﻿

(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 ﻿

(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 ﻿

(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 ﻿

(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 ﻿

(Swinburne Commons, 2013)
The following PhysCast deals with a non-uniform 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 ﻿

(Swinburne Commons, 2013)
This PhysCast deals with rotational motion. A merry-go-round 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 ﻿

(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 ﻿

(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 ﻿

(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 ﻿

(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 ﻿

(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 ﻿

(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 Steam-Ice Mixture ﻿

(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?
