This video will introduce latent heat and then we will consider phase transitions.

In which case do you think we will observe the most dramatic result?

Watch the video below. It defines isothermal, isobaric and isovolumetric processes.

Define the processes in the image below.

What will happen to the temperature when the membrane is broken?

A block moves with uniform circular motion because a chord tied to the

block is anchored at the centre of a circle. Is the power due to the

force on the block from the chord positive, negative or zero?

Air resistance, like friction, is a force which opposes the motion of an object.

Which of the following properties of a falling object do you predict will influence the size of the air resistance force?

In lecture 4 you learnt a little about circular motion. We are now going to combine what you have learnt about forces with circular motion.

Consider the forces acting on a car as it does a loop-the-loop trick.

List

the forces acting on the car at the top of the loop. Do not include the resultant force (as this is the result of the other forces it is not a force acting on the car).

Does

a mass on a spring obey the kinematic equations?

True or False; you need to complete the

Lab Safety Quiz (score 100%)

Lab Skills Quiz (score 100%)

and acquire the lab manual (see week 1 page) before the lab this week.

(Note: if you don't complete the Quizzes your lab mark will be zero!)

The emergency evacuation area is the Physics Lawn. In case of an emergency, follow the instructions from your demonstrator.
