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 estimate the gradient of a curved part of the graph by considering the gradient of a straight line connecting two points. Key learning points: - The gradient of a curve can be estimated. - You can estimate by drawing...

Pupil outcome: I can combine compound measures, calculating overall speed. Key learning points: - Two speeds can be combined to give an overall average speed. - Average speed is the total distance travelled divided by the total time taken.

Pupil outcome: I can convert between metric speed measures. Key learning points: - Sometimes speed is measured in different units. - The units for speed can be converted to alternative units. - When converting, it can be helpful to think...

Pupil outcome: I can use my knowledge of rounding, estimation and bounds to solve problems. Key learning points: - Rounding and estimation are practical maths skills. - Sometimes you will need to apply common sense to rounding in...

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...

Pupil outcome: I can use compound measures for speed. Key learning points: - Average speed can be calculated by dividing the distance travelled by the time taken. - The units for time and distance determine the units for speed. - By...

Pupil outcome: I can appreciate what is meant by a suitable degree of accuracy. Key learning points: - When calculating often 3 significant figures is the required degree of accuracy. - When working with integers in context different...

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.

This video discusses how to solve distance rate time word problems with systems of equations. You will often see these types of problems dealing with two different trains, or two different airplanes, traveling in the same or different...

How do you set up distance-rate-time word problems and use a system of equations? This video shows how to use a table to organize information and write the needed equations to solve the system.

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...
