This PhysCast is about simple harmonic motion. A 0.12 kg body undergoes simple harmonic motion of amplitude 8.5 cm and a period of 0.20 s. (a) What is the magnitude of the maximum force acting on it? (b) If the oscillations ...

In this PhysCast we are asked to consider the motion of a uniform cylinder of mass m and radius R as it rolls smoothly down a ramp at angle theta to the horizontal. We are asked to find an expression for the linear ...

This PhysCast examines the question: we have a mass-less spring with k = 74 N/m and it is hanging from the ceiling.

In this PhysCast we are asked to find the average translational kinetic energy and the thermal speed of oxygen gas molecules.

This PhysCast deals with simple harmonic motion where dampening is present. The amplitude of a lightly damped oscillator decreases by 3.0% during each cycle. a) What percentage of the mechanical energy is lost in each ...

This PhysCast is about simple harmonic motion. Two springs are attached to a block which can oscillate on a frictionless floor. If the left spring is removed it oscillates at a frequency of 30 Hz. If instead the right ...

A fully loaded Volvo station wagon has a mass of 1950kg. If each of its four tires is inflated to a gauge pressure of 230kPa, what is the total tire area in contact with the road?

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

In this PhysCast we are asked to find the centre of mass of a hexagon with six equal sides of length a, but where one of the triangles is missing.

This question deals with both hydrostatics and hydrodynamics. A 4.0cm diameter horizontal pipe connects passes through a freshwater dam at a depth of 6.0 meters and is sealed by a plug. A) Find the magnitude of the frictional ...
