The third and final part of the block collision sequence.

Mr. Andersen shows you how to draw free body diagrams of various objects. The major forces (like gravity, normal, tension, friction, air resistance, etc.) are discussed and then applied to various problems.

Last time we talked about what curvature means, looked at geodesics, great circles on spheres, and tried to understand the notion of "straightness". This week on Spacetime, we take a detour into how geometry works in spacetime. Get...

"How fast are you moving?" seems like an easy question, but it's actually quite complicated -- and perhaps best answered by another question: "Relative to what?" Even when you think you're standing still, the Earth is moving relative to...

This video discusses Newton's first law of motion, also known as the law of inertia. It explains how Newton built upon the experiments of Galileo to formulate this law. The video illustrates the concept using the example of a ball on the...

Pupil outcome: I can use my knowledge of graphical representations to solve problems. Key learning points: - When presented with a real-life problem, it can help to sketch what is happening. - A sketch can provide a visual aid for...

Pupil outcome: I can deduce that the area under a speed-time graph gives the distance travelled and deduce how this may be calculated. Key learning points: - Distance travelled is calculated by multiplying speed and time. - This is...

Pupil outcome: I can use my knowledge of interpreting real-life graphs to solve problems. Key learning points: - Real life graphs present a visual model of a situation. - Linear graphs are not always the best representation. - The...

Pupil outcome: I can model real-life situations graphically. Key learning points: - Distance-time graphs tell you how far you have travelled over a period of time. - By reading the graph, you can tell if there is mistake with it. - You...

Pupil outcome: I can interpret graphs that model real-life situations graphically. Key learning points: - Distance-time graphs can tell you about a journey. - By reading the graph, you can tell if there is mistake with it.

Pupil outcome: I can calculate time intervals and acceleration of sections of a speed/time graph. Key learning points: - In a speed-time graph, a horizontal line means the speed did not change during that time. - A slanted line means the...

Pupil outcome: I can interpret non-linear distance-time graphs. Key learning points: - Speed may not always be constant. - Acceleration may not always be constant. - Depending on the variables, multiple graphs can represent the same...

Pupil outcome: I can draw a distance-time graph to model a journey. Key learning points: - You can sketch a graph based on the information you have been given. - Important given values should be marked on your sketch. - On a...

Pupil outcome: I can interpret and draw more real-life graphs. Key learning points: - Not all real-life graphs can be drawn using sections of different linear graphs. - The graphs are models, which means that we want them to be useful.

Pupil outcome: I can use my knowledge of graphing linear relationships to solve problems. Key learning points: - Real life relationships can be represented using a linear graph. - Real life problems can be solved using a linear graph. -...

This content provides a step-by-step solution for a physics problem involving a crate pushed at a constant speed up a frictionless inclined plane by a horizontal force. It demonstrates how to apply Newton's Second Law by resolving forces...

Understand the physics of uniform circular motion, its requirements, and key formulas like centripetal acceleration. Learn real-world examples, distinctions from non-uniform motion, and the derivation of UCM equations

Learn about the basics of 1-dimensional motion in this informative video! We'll cover the relationship between distance and time, and how to read and interpret distance-time graphs. Perfect for students studying physics or anyone looking...

The video discusses a 2014 U.S. Physics Team exam question about the shape of a cable hanging from a helicopter flying horizontally. The experiment showed that when flying at a constant speed, the rope hangs diagonally to the left due to...

In this math video we will learn how to compare & interpret a graph. We will connect unit rate to slope or constant of proportionality on the graph. We will write an equation using the unit rate. As we compare two lines on the graph we...

Researchers at the University of Southampton have successfully converted a standard car into a hybrid electric petrol vehicle. This innovative design features a small petrol engine that runs at a constant speed, driving a generator to...
