Physics (from ancient greek: the most notable innovations were in the field of optics and vision, which came from the works of many scientists like ibn sahl. Directions: in this activity you will set up mirrors so you can figure out how a periscope works draw a long horizontal line on the board using a ruler. A floating object is displacing fluids that would otherwise fill the space it occupies for example, a ball floating motionless on water is displacing the water and air that would normally be where the ball is. The global positioning system (gps) is a network of about 30 satellites orbiting the earth at an altitude of 20,000 km the system was originally developed by the us government for military navigation but now anyone with a gps device, be it a satnav, mobile phone or handheld gps unit, can receive the radio signals that the satellites. Physics is a branch of science it studies matter, and all forces and their effects the guesses are compared to the way the real world works.

Energy is a word that's used a lot here, you'll learn about how it's one of the most useful concepts in physics along the way, we'll talk about work, kinetic energy, potential energy, conservation of energy, and mechanical advantage. In physics, a force is said to do work if, when acting, there is a displacement of the point of application in the direction of the force for example, when a ball is held above the ground and then dropped, the work done on the ball as it falls is equal to the weight of the ball (a force) multiplied by the distance to the ground (a displacement.
