We humans have always been explorers. The great civilizations that have arisen across the world are owed to our restless ancestors. These days, there’s not much of Earth left to explore. But if we look up, there’s a whole universe out...

Our modern skies are filled with these flying tubes as they shuttle hundreds of thousands of people around the world every day, but even more impressive than their numbers is the science and engineering that makes airplanes work.

It used to be that you could get on a Concorde jet and fly across the Atlantic ocean faster than the speed of sound, but what does the future hold for supersonic flight?

An unbelievable play on an American football field is the perfect backdrop for understanding crucial physics concepts. Michelle Buchanan goes play-by-play on the vectors, the scalars, and the glory of a downright scientific touchdown.

In this video Paul Andersen explains how the temperature is a measure of the average kinetic energy of particles in an object. The temperature is proportional to the average kinetic energy according to the Kelvin scale. At absolute zero...

Transportation is a big part of our world and engineers play a big role in making it happen. Today we’ll explore how transportation systems are designed and some things transportation engineers have to take into consideration, like...

How the heck do we map out a planet without oceans? NASA had to figure that out when we sent the Mariner 9 probe to Mars. There's some tricky, yet fascinating science behind all of it! In this episode of Crash Course Physics, Shini talks...

Understanding how velocity is calculated is essential if you are to grasp the laws of physics. Learn the calculations necessary to figure it out.

Pupil outcome: I can clearly describe how to measure speed and explain how I can do this accurately. Key learning points: - The instantaneous speed of an object is the speed at a particular moment in time. - For an accurate measurement a...

This content provides a detailed example of vector motion, analyzing a plane's journey in two segments. It demonstrates how to calculate the total displacement (magnitude and direction) using vector notation, determine the average...

Learn the key differences between average velocity and average speed, and why they matter in analyzing motion. We’ll use simple motion scenarios and velocity-time graphs to explore how direction affects velocity, but not speed.

Calculus is a branch of mathematics that deals with very small changes. Calculus consists of two main segments—differential calculus and integral calculus. Differential calculus primarily deals with the rate of change of things, while...

Heat death of the universe, also called The Big Chill or Big Freeze, will happen when the entropy of the universe will be so high that everything and everyone that lives in it will perish. This will happen because an organism living in...

This is one of these questions where most feel like they should know the answer, many seem to know the answer, but then somehow everyone tells a different story. In this deep dive, we get to the bottom of why it is really cold in the...

In this video, a math teacher demonstrates how to interpret a graph and answer standardized math test questions. The teacher covers topics such as finding the distance a car traveled in a certain amount of time, calculating the average...

This Free Response Question includes the following concepts: Graphing Velocities of Carts during a Collision, Conservation of Linear Momentum, Conservation of Energy and Elastic Collisions.

Equations to memorize for the AP Physics 1 Exam.

We need to know the initial velocity of a projectile leaving the Nerd-A-Pult. That means we need the initial speed and the initial angle. This video shows exactly how I measured both.

Practical - Force and Acceleration

See how different attributes are naturally selected in different environments, and note some core principles of evolution along the way.

This video is an example problem that walks through finding the average speed for the last 2 laps of the 4 lap qualifier for the Indianapolis 500 assuming an average speed for the first 2 laps. It is actually more difficult than it...

In this video, the teacher explains how to calculate the average speed for two different modes of transportation by using the distance formula and solving a simple rational equation. The teacher provides an example of a scenario where a...

This is a lecture video on the topic of calculating speed. The video explains how to calculate the speed of an object based on its distance travelled and time taken. The presenter uses simple examples to illustrate the equations used to...
