street was crowded with cars‚ vans‚ busses and even motorcycle waiting to pick up the children after school. They parked haphazardly along the street make it difficult for people to cross the street. Other vehicles were speeding along even there was speed limit sign. Suddenly‚ I saw a young boy who was running quickly without looking to the left or to the right to cross the street. The vehicles honked mercilessly on the street. Unfortunately‚ a motorcycle hit the unlucky young boy. The boy was flung

WEDNESDAY‚ March 13 (HealthDay News) -- More than half of all teens and young adults in the United States know a victim of dating violence or sexual assault‚ according to a new national survey. But 53 percent would find it difficult to intervene‚ and 40 percent wouldn’t even know what to do if they witnessed such a crime‚ the poll found. The survey "uncovers the grim reality of dating violence and sexual assault among 15 to 22 year olds‚ and the fact that so many are uncertain about the warning signs

Special Theory of Relativity means a physical theory of relativity based on the assumption that the speed of light in a vacuum is a constant and the assumption that the laws of physics are invariant in all inertial systems. Albert Einstein created many different experiments one being where Mrs. Einstein is standing in a field and Mr. Einstein is standing

From the theorised properties of the electromagnetic spectrum‚ Maxwell also predicted the speed of light and its relation to the electromagnetic spectrum. However‚ as light was concluded as a wave it was presumed light required a medium to be

Physics HSC Notes Space 1. Earth has a gravitational field that exerts a force on objects both on it and around it. K1 Define weight as the force on an object due to a gravitational field. Mass is the amount of matter within an object‚ measured in kg Weight is the force of gravity acting on an object’s mass measured in newtons (N). Weight is a force thus a vector quantity. K2 Explain that a change in gravitational potential
