The questions in this quiz are suitable for GCSE physics students studying gravitational fields, weight, mass and gravitational field strength, how to calculate work done, free body diagrams and ...

Students learn how mass and distance affect the force of gravity between objects. Gravity: Students learn how mass and distance affect the force of gravity between objects, and how to apply Newton’s ...

Our standard model of elementary particles and forces has recently become as close to “complete” as we could conceivably ask for. Every single one of the elementary particles — in all their different ...

Here’s what you’ll learn in this story. A new paper uses a simplified model to prove that gravity can be unified between quantum and standard physics. The simpler model still meets the established ...

In a bold step toward solving one of science’s most puzzling problems, researchers have proposed a new way to bring gravity into the same mathematical language as the other forces of nature. While the ...

The terms weight and mass are often used incorrectly. Phrases like ‘a bag of sugar weighs 1 kg’ are not scientifically correct. This means that a 1 kg mass would be attracted to Earth by a force of 10 ...
