#### PhysCasts: Shaking a Container of Water

(Swinburne Commons, 2013)

This PhysCast is about the first law of thermodynamics. A closed by uninsulated container at room temperature containing 1 kg of water is shaken violently until the temperature rises by 5 degrees C. The mechanical work ...

#### PhysCasts: Kid on a See-Saw

(Swinburne Commons, 2013)

This PhysCast is going to look at a problem involving static equilibrium. A 60 kg child sits at the end of a 2.4 metre board supported by a pivot, 80 cm away, and a scale at the other end. If the scale reads zero, what is ...

#### PhysCasts: Simple Harmonic Motion Maths

(Swinburne Commons, 2013)

This PhysCast explores the mathematics of simple harmonic motion.

#### PhysCasts: Jumping onto a Merry Go Round

(Swinburne Commons, 2013)

This PhysCast will look at a problem involving a merry go round with some people jumping onto it.

#### PhysCasts: Newton's Cradle: An Example of Elastic Collisions

(Swinburne Commons, 2013)

This PhysCast is going to look at a very commonly used example in collision physics - the Newton's Cradle.

#### PhysCasts: Heat Flow in a Cyclic Process

(Swinburne Commons, 2013)

This PhysCast is going to examine an example of using the first law of thermodynamics to analyse a cyclic process.

#### PhysCasts: Heat Conduction Along a Gold/Silver Rod

(Swinburne Commons, 2013)

This PhysCast is going to look at heat flowing through a material by conduction. Two identical sized rods, one made of gold and one made of silver, are joined end to end. The gold end is placed in boiling water and the ...

#### 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.
