... Newton's Laws . ... Mass . ... The most familiar force is weight, the downward force on an object due to gravity. ... In the absence of opposing forces, if a force does act on an object at rest or moving at constant speed, it accelerates in the direction of the force. ... By Newton's second law, the acceleration a of an object is proportional to the force F acting on it and inversely proportional to its mass m. Expressing F in newtons we now get a --for any acceleration, not just for free fall--as ....

... Perhaps surprisingly to people outside the field, many educators object to "teaching relativity in grade school" on the grounds that students as young as ten lack the intellectual sophistication necessary to form a meaningful notion of the equivalence between mass and energy. ... All the matter in the universe condensed out of pure energy over a period of about 700,000 years shortly after the Big Bang, and today, stars shine because matter at their centers is being slowly converted back into energy....

... The sharp vision of Hubble's Advanced Camera for Surveys uncovered the speedy white dwarfs in the ancient globular star cluster NGC 6397, a dense swarm of hundreds of thousands of stars. ... The distribution of young white dwarfs is the exact opposite of what we expected," said astronomer Harvey Richer of the University of British Columbia in Vancouver. ... The idea that young white dwarfs are born with a kick was suggested 30 years ago to explain why there were so few of them in open star clusters....
