#### PhysCasts: Calculating Density and the Uncertainty in the Density

(Swinburne Commons, 2014)

This is a numerical error propagation example where we're asked to find the density and uncertainty in density of two objects.

#### 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: 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: Two Connected Masses on Slopes (With Friction)

(Swinburne Commons, 2014)

In this PhysCast we are asked to consider the motion of two blocks connected by a cord. Block A has a mass mA = 4.0kg, and block B has a mass mB = 2.0kg. The coefficient of kinetic friction between block B and the horizontal ...

#### PhysCasts: 2D Motion: Washout!

(Swinburne Commons, 2014)

This is a PhysCast on 2 dimensional motion. A raging flood has washed away a section of highway, creating a gash 1.7 meters deep. A car moving at 31 m/s goes straight over the edge. How far from the edge of the washout ...
