## Physics

### Moments of the System

Applications of Integrals: Physics

Learn how to find the moments of a system given point masses and their coordinates.

### 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.

### 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.

### 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.

### 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.

### 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.

### Electrical Safety

In "Electrical Safety", we first look at the dangers of electric shocks by actually demonstrating an electric shock. We then look at the safety features built into our homes and electrical devices that keep us safe from electric shocks.

### Sources of Electricity

In 'Sources of Electricity', we take a detailed look at where our electricity comes from: thermal and hydroelectric power stations, wind farms, and solar farms. We alo examine the advantages and disadvantages of these sources of electricity.

### 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.

### 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.

### Uniform Circular Motion

When an object moves along a circular path at a constant speed, its motion is called uniform circular motion. Uniform circular motion is an accelerated motion.
