#### PhysCasts: Sinusoidal Waves

(Swinburne Commons, 2013)

Video explains that a wave on a taut wire is described by the equation y=1.5sin(0.10x-560t), where x and y are in cm and t is in seconds. Find the: a) Amplitude, b) Wavelength, c) Period, d) Wave speed of the wave.

#### PhysCasts: Energy in Rotation: Anchor Example

(Swinburne Commons, 2013)

This problem is worked through: an anchor of mass 500kg is attached to a light cable that passes over a roller of negligible mass and winds around a hollow cylindrical drum of radius 1.2m and mass 250kg which can rotate ...

#### PhysCasts: Rolling Motion and Energy Conservation

(Swinburne Commons, 2013)

This question is about rolling motion and conservation of energy. A solid sphere and a solid disc with identical masses and radii roll down a slope without slipping. Using energy considerations, which has the greatest ...

#### 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: 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: Energy and Rotational Motion

(Swinburne Commons, 2013)

This question is about energy and rotational motion. A bowler bowls a 160g cricket ball with a diameter of 7cm with a linear velocity of 144km/h. The ball is measured to rotate at 22250 r.p.m. What proportion of the ball's ...

#### PhysCasts: 1 Dimensional Motion: A Coin in a Well

(Swinburne Commons, 2013)

This problem is about 1D motion. A coin is dropped into a wishing well. A noise is heard when it hits the bottom 1.8s after it is dropped. How deep is the well?

#### PhysCasts: Simple Harmonic Motion: Pendula

(Swinburne Commons, 2013)

This problem is about simple harmonic motion. A Grandfather clock contains a ball with a diameter of 5 cm suspended from a light, inextensible wire. A modern clock has a think metal rod instead of a ball and wire. Both ...
