The following PhysCast is about a sphere which is attached to a wall. A uniform sphere of mass m = 0.85 kg and radius r = 4.2 cm is held in place by a mass-less rope attached to a friction-less wall a distance of L = 8.0 ...

This PhysCast describes a question which deals with a wave which is travelling along a string.

This PhysCast looks at a conservation of energy problem. A 60 kg skier leaves the end of a ski-jump ramp with a velocity of 24 m/s directed 25 degrees above the horizontal. Suppose that as a result of air drag the skier ...

This PhysCast deals with constructing a wave equation from some given information in a diagram.

This PhysCast is about oscillatory motion. Two identical springs of spring constant 7580 Nm-1 are attached to a block of mass 0.295 kg. What is the frequency of oscillation on a friction-less floor?

This Physcast asks us to consider the motion of a block which is falling onto a spring. A 250g block is dropped onto a relaxed vertical spring that has a spring constant k = 2.5 Ncm-1. The block becomes attached to the ...

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 ...

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?

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 ...

This PhysCast explores the mathematics of simple harmonic motion.
