#### PhysCasts: The Unusual Wheel

(Swinburne Commons, 2013)

The following PhysCast deals with the situation involving this unusual looking wheel. A constant horizontal force of 10 N is applied to a wheel of mass 10 kg and radius 0.3 m. The wheel rolls smoothly on a horizontal ...

#### 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: Acceleration in a Uniform Circular Motion

(Swinburne Commons, 2013)

This video is about acceleration in uniform circular motion. This problem is worked through: A jet is diving vertically downward at 1080 km/hr. The pilot will lose consciousness if the acceleration exceeds 5g. At what ...

#### 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: Uniform Circular Motion: Plane Banking

(Swinburne Commons, 2013)

This problem is about uniform circular motion. A plane turns by banking at an angle of 30 degrees horizontally. If the radius of curvature of the turn is 10km and the plane maintains a constant height above the ground, ...

#### PhysCasts: Standing Waves

(Swinburne Commons, 2013)

This question is about standing waves on a string. A wire 37cm long is clamped at both ends The wave speed along the wire is 324.6 m/s. Find a) The standing wave with the longest wavelength that can exist on this wire? b) ...

#### PhysCasts: Uniform Circular Motion

(Swinburne Commons, 2013)

This PhysCast is about uniform circular motion. A puck of mass m1 is rotated in a circle of radius R on a frictionless air-hockey table. It is connected to a stationary, suspended mass m2 by a cord passing through a hole ...

#### 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.
