## Series: Physics: Senior Secondary

### Acceleration

With Pilot Mitchell's help, Lotus Lang continues hunting for clues. Will she strike gold and pick up the lost trail? This lesson will lay the foundations for understanding acceleration and its close relationship with velocity.

### Acceleration-Time Graphs

Dylan gives Lotus a VIP tour of Lexicorp's state-of-the-art facilities. On the surface, she's here to buy stuff, but secretly, she's investigating the link between Lexicorp and the missile launch! This lesson will apply acceleration-time graphs...Show More

### Accuracy

The royal archery contest begins! Everyone expects Robin Hood to win since he is an accurate and reliable archer. But what do the terms accuracy and reliability mean? This lesson will take an in-depth look at accuracy and systematic errors,...Show More

### Converting between Graphs of Motion: Areas

The cunning Carmen breaks into a jewellery store and steals \$5 million in diamonds! Vector Man can't help because he is crippled by hunger. Will the police be able to catch her? This lesson will outline how to convert between graphs of motion by...Show More

### Converting between Graphs of Motion: Gradients

In a repeat of the failed dinner date at Hopeless Ramentics, Mark Brent leaves Lotus to stop a robbery and save the day! That is, until he falls prey to his ultimate weakness! This lesson will introduce how to convert between graphs of motion,...Show More

### Distance and Displacement

Mark Brent and Lotus Lang are Hopeless Ramentics - or so it seems. Things are about to explode! This lesson will discuss the differences between distance and displacement.

### Distance-Time and Displacement-Time Graphs

Mark Brent's coffee run takes a turn for the worse when he has a nasty encounter with Negative Nancy! This lesson will discover the importance of distance-time graphs and displacement-time graphs for representing motion.

### Equations of Motion: Calculations

Deep underground, Carmen and Alexandra 'Lexi' Luthor perform a top-secret science experiment. Will they unlock the power to rival Vector Man? This lesson will perform calculations using the equations of motion for uniform acceleration.

### Equations of Motion: Derivations

Lotus gets up early to train for an upcoming marathon. Watch her tackle the infamous heartbreak hill! This lesson will derive the equations of motion for uniform acceleration using a velocity-time graph.

### Escape Velocity

We've all heard the saying, â€œwhat goes up must come back down.â€ But when we launch rockets and satellites into space, they (usually) don't come back! Let's prove this saying wrong, using Physics! This lesson will introduce and derive...Show More

### Gravitational Force

Gravity is a heart-warming story of attraction. These farm animals would fall for each other even if the laws of Physics stop working! This lesson will formally revisit the gravitational force (from year 11), focusing on Newton's Law of Universal...Show More

### Measuring Gravity: Evaluation

The results are in - gravity is weaker than it should be! Lotus is certain that someone is digging a giant cave underneath the Big Apple, but Mark isn't convinced. Who do you think is correct? This lesson will assess the accuracy, reliability and...Show More

### Measuring Gravity: Experiment

Black Friday is normally celebrated with sales and shopping sprees, but this year, someone is tinkering underground. Will Mark, Georgie and Lotus discover Lexi Luthor's lair? This lesson will introduce a simple experiment to measure the...Show More

### Reliability: Part 1

A new contender joins the archery contest... Will they be a match for Robin Hood? Only time (and repeated trials) will tell! This lesson will explore the concept of reliability, including the subtle difference between accuracy and precision.

### Reliability: Part 2

We know that Robin Hood is an accurate and reliable archer, but just how good is he? Is his aim god-like, or is he subject to the errors and imperfections of mortals? This lesson will continue investigating the concept of reliability, including...Show More

### Scalars and Vectors

The newest superhero on the block, Vector Man, faces his first challenge - a runaway train! This lesson will begin from the basics by introducing scalars and vectors.

### Speed and Velocity

While Mark Brent snoozes through his alarms, Lotus Lang is hot on the missile's trail. Can she catch the culprits? This lesson will compare and contrast speed and velocity.

### Speed-Time and Velocity-Time Graphs

Inmates are escaping the city's jail! While Vector Man rounds up the prisoners, Lotus Lang learns Mark Brent's closest secret. This lesson will utilise speed-time graphs and velocity-time graphs to represent motion.

### Units: Part 2

Exam tip: one mark in Physics exams may come from using the correct units. So, if you write and use SI units in all calculations (a pretty simple task), you'll get a free mark! If only the rest of the exam was that easy! This lesson will continue...Show More

### Units: Part 1

The Ancient Greeks believed that everything is made by combining four elements: earth, water, air and fire. It turns out that there's actually seven elements in science - watch this video to find out what they are! This lesson will introduce the...Show More

### Validity

The archery contest has a long list of rules, but Chelsea the Cheater keeps breaking them! How does this affect the outcome (conclusion) of the competition? This lesson will begin our analysis of validity by examining the importance of the...Show More
