Learn how to get started with Prezi and get a few design ideas.

Physical Science for Kids is the fun way to learn important facts about physical science and get ready for tests. Take a fascinating journey to the Super Science Station to learn about lab safety, the scientific method, atoms, molecules,...

Mr. Andersen explains the importance of physics as a science. History and virtual examples are used to give the discipline context.

Wondering how you can catch the perfect wave? Dive into the fascinating and complex physics of surfing. -- Whether or not you realize it, surfers are masters of complicated physics. The science of surfing begins as soon as a board...

In the third act of "Swan Lake", the Black Swan pulls off a seemingly endless series of turns, bobbing up and down on one pointed foot and spinning around and around and around thirty-two times. How is this move - which is called a...

Thermometers might seem like a basic instrument, but science would not be the same without them, and they helped us understand one of the most important ideas in all of science: the conservation of energy.

The urge to jump or high place phenomenon apparently springs from a distortion of our perceptions. Lab tests have shown that people estimate disgusting things, such as feces, to be closer than they really are. Another example is...

Nuestros pulgares son instrumentos complejos; necesitamos un gran cerebro para controlarlos. ¿Son los pulgares la razón de la evolución de la superior inteligencia humana?

A Level Physics. Doodle Science teaches you GCSE and A Level physics in a less boring way in almost no time!

Quantum physics deals with the foundation of our world – the electrons in an atom, the protons inside the nucleus, the quarks that build those protons, and the photons that we perceive as light. These constitute everything that we are...

In this video, we will show you how to design and implement a custom Profile Bio that's both informative and engaging.

When were talking about motion, it can be very useful to draw a graph. If you're moving in a straight line, a graph that's useful is a distance-time graph; this is where you have distance on the Y-axis and time on the X. If we mark this...

👉 Learn how to simplify mathematics expressions. A mathematis expression is a finite combination of numbers and symbols formed following a set of operations or rules. To simplify a mathematics expression means to reduce the expression...

In this video Paul Andersen explains how simple harmonic motion occurs when a restoring force returns an object toward equilibrium. The two types of harmonic motion studied in AP Physics are the mass spring oscillator and the simple...

In this video Paul Andersen explains how a net torque acting on an object will create rotational motion. This motion can be described by the angular displacement, angular velocity, and angular acceleration. The linear velocity can be...

Bridges... bridges, bridges, bridges. We talk a lot about bridges in Physics. Why? Because there is A LOT of practical physics that can be learned from the planning and construction of them. In this episode of Crash Course Physics, Shini...

Did you know that, at a certain point on a moving wheel... there's no motion? I mean, kinda... it's all relative, right? Prepare to have your mind blown in this episode of Crash Course Physics where Shini delves into the world of...

In this video Paul Andersen describes motion as the movement of an object over time. Displacement, velocity and acceleration are all defined. An experiment in motion is used to calculate velocity and acceleration of a tennis ball.

In this, THE FIRST EPISODE of Crash Course Physics, your host Dr. Shini Somara introduces us to the ideas of motion in a straight line. She talks about displacement, acceleration, time, velocity, and the definition of acceleration. Also,...

The constant motion of our oceans represents a vast and complicated system involving many different drivers. Sasha Wright explains the physics behind one of those drivers -- the concentration gradient -- and illustrates how our oceans...

The standard story of the Scientific Revolution culminates with the long life of one man: Sir Isaac Newton—a humble servant of the Royal Mint, two-time parliamentarian, and a scientific titan whose name, along with Einstein’s, is...

So we've all heard of relativity, right? But... what is relativity? And how does it relate to light? And motion? In this episode of Crash Course Physics, Shini talks to us about perspective, observation, and how relativity is REALLY weird!

What is torque? This is one of those things that you may have heard about in passing but never really understood. In this episode of Crash Course Physics, Shini sits down with us to discuss what torque is, how it works, why it works, and...

Paul Andersen introduces forces, motion, and Newton's three laws in this video. He begins by describing forces as pushes or pulls on objects that produce motion. A lack of motion results from a balanced set of forces. A teaching...
