#### PhysCasts: The Length of a Vibrating Spring

(Swinburne Commons, 2013)

This PhysCast is going to look at standing waves on a stretched string. A 45 gram string is tightly stretched and fixed firmly at each end. The tension in the string is 78 N, and it vibrates with its 3rd harmonic at 120 ...

#### PhysCasts: Tossing a Ball Attached to a Spring

(Swinburne Commons, 2013)

This PhysCast will analyse a motion problem using conservation of energy. A 1.25 kg ball is attached to the ground by a spring with k = 22 N/m and upstretched length of 0.55 m. The ball is thrown straight upwards, being ...

#### PhysCasts: Stopping a Rotating Satellite

(Swinburne Commons, 2013)

This PhysCast will apply Newton's second law of motion in its rotational form. A cylindrical satellite is 1.4 m in diameter with its 940 kg mass distributed uniformly. The satellite is spinning at 10 rpm but must be stopped ...

#### 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: 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: Torque on a Hinged Rod

(Swinburne Commons, 2013)

In this problem we will look at calculating the torque on an object about an axis. A uniform rod of 1.5 m and mass 0.80 kg is attached at one end to a hinge on a vertical wall. The rod makes an angle of 60 degrees above ...

#### PhysCasts: Cyclist Accelerated by the Wind: A 2-D Vector Problem

(Swinburne Commons, 2013)

We are going to look at a problem that is an example of a 2-d vector calculation. A cyclist travels along a horizontal road and 5.5 m/s. A strong wind blows from one side for 1 minute, after which the cyclist is moving at ...
