#### PhysCasts: Acceleration of an Ice Puck

(Swinburne Commons, 2014)

A 0.20 kg puck upon a frictionless ice surface is acted on by the forces shown in the diagrams. Find the resulting accelerations?

#### PhysCasts: Analyzing Laboratory Data

(Swinburne Commons, 2014)

This PhysCast focuses on the laboratory analysis techniques that you are required to use in energy and motion in the 5 labs.

#### PhysCasts: Error Propagation

(Swinburne Commons, 2014)

In this PhysCast we look at how you can propagate errors in laboratory measurements.

#### PhysCasts: Time for Coffee

(Swinburne Commons, 2013)

A small electric immersion heater is used to heat 100 g of water for a cup of instant coffee. The heater is labelled "200 Watts" (it coverts electrical energy into thermal energy at this rate). Calculate the time required ...

#### PhysCasts: A Gas Expands with a Constant Temperature

(Swinburne Commons, 2013)

This PhysCast is about thermodynamic processes. One mole of oxygen (assume it to be an ideal gas) expands at a constant temperature of 310 K from an initial volume V1 = 12 L to a final volume V1 = 19 L. How much is done ...

#### PhysCasts: Expansion of Liquids and Solids with a Change in Temperature

(Swinburne Commons, 2013)

An aluminum cup of 100 cm3 capacity is completely filled with glycerine at 22 degrees C. How much glycerine, if any, will spill out of the cup if the temperature of both the cup and the liquid is increased to 28 degrees C?

#### PhysCasts: Power Exerted Riding a Bike at Constant Velocity

(Swinburne Commons, 2014)

This PhysCast is about power and velocity. Riding your 14kg bike at a steady 18km/h (5.0 m/s) you experience a 30-N force from air resistance. If your mass is 68 kg what power must you supply on level ground and going up ...

#### PhysCasts: Motion of an Electric Vehicle

(Swinburne Commons, 2014)

This PhysCast deals with one dimensional motion. An electric vehicle starts from rest and accelerates at a rate of 2.0 m/s2 in a straight line until it reaches a speed of 20 m/s. The vehicle then slows at a constant rate ...

#### PhysCasts: Accelerating Merry Go Round

(Swinburne Commons, 2013)

This PhysCast deals with rotational motion. A merry-go-round rotates from rest with an angular acceleration of 1.50 rad/s2. How long does it take to total through the (a) first 2.00 rev and (b) the next 2.00 rev?

#### PhysCasts: A Suspended Nonuniform Bar

(Swinburne Commons, 2013)

The following PhysCast deals with a non-uniform bar which is suspended and in static equilibrium. A nonuniform bar is suspended at rest in a horizontal position by two massless cords. One cord makes the angle theta = 36.9 ...
