Physics is the science of understanding and predicting the behavior of matter and energy in the universe. One of the fundamental aspects of physics is the study of power, which is defined as the rate ...

Understanding the relationship between force, mass, and acceleration is a fundamental concept in physics. This relationship, known as Newton’s second law of motion, states that the acceleration of an ...

Learn how to calculate the universal gravitational force between two objects! This video explains Newton’s Law of Gravitation, walking you through the formula, units, and a step-by-step example to ...

Work close workEnergy transferred by a force. Work done = force × distance moved in the direction of the force. is done when energy is transferred from one store to another. Work is also done when a ...

When David Politzer, Caltech's Richard Chace Tolman Professor of Theoretical Physics, was a fourth-year graduate student at Harvard in 1973, he made an astounding discovery that would forever reshape ...

I love including numerical calculations in my introductory and advanced physics courses. I find that including coding in the introductory physics course forces students to think in different ways to ...

It is important to remember that the distance is the perpendicular distance from the pivot to the line of action of the force. A force of 15 N is applied to a door handle, 12 cm from the pivot.

When it comes to measuring the "hardness" of a material, most tests are distinctly low-tech and basically involve pressing a diamond tip into the surface and measuring the size of the dent produced.

Zoltan Fodor receives funding from DFG, BMBF. When the results of an experiment don’t match predictions made by the best theory of the day, something is off. Fifteen years ago, physicists at ...

The strongest force in the universe is called, aptly, the strong force. We never get to witness its fearsome power because it works only across subatomic distances, where it binds quarks together ...
