Physics studies the behavior of matter, energy, and the forces acting upon them. Objects have mass and weight, and their stability depends on the center of mass and base area. Forces can be contact or distant, producing acceleration, moments, or friction, and follow Newton’s laws of motion. Moving objects have momentum, and energy exists in multiple forms including kinetic, potential, chemical, electrical, nuclear, magnetic, light, sound, and heat, which obey the principle of conservation of e...
