  • Propels The Rocket In The Opposite Direction
    465 words
    A rocket in its simplest form is a chamber enclosing a gas under pressure. A small opening at one end of the chamber allows the gas to escape, and in doing so provides a thrust that propels the rocket in the opposite direction. Newton's laws can be used to explain this his laws in the simplest terms can be explained like this: First law- Objects at rest will stay at rest and objects in motion will stay in motion in a straight line unless acted upon by an unbalanced force. Second law- Force is eq...
  • Air Pressure
    951 words
    Pressure Pressure, is the ratio of a force acting on a surface, to the area of the surface; it is thus distinct from the total force acting on a surface. Units of pressure are force units divided by area units. Examples of these are pounds per square inch, dynes per square centimeter, or newtons (N) per square meter (Pressure n. pay). Pressure has many influences and effects on objects. When the pressure rises, it affects the melting point and the boiling point of a substance. This causes the ra...
  • Close The Valve The Pressure

  • Buoyancy And Many Other Forces
    437 words
    Scuba diving is an activity enjoyed by people all over the world. Scientists use it to study underwater life, police use it to train in case of emergencies, and many others do it just for fun. What many people don't know, though, is that scuba diving would be impossible without physics. Pressure, buoyancy, and force are big parts of diving. Pressure, the weight pushing on something, is a vital part of scuba diving. As a diver sinks deeper into the water, the pressure pushing on the person's lung...
  • Destructive Force Of The Bomb
    509 words
    The stories and events that unfold in John Hersey's, Hiroshima, have certainly been eye-openers for me. As a child in middle school and high school I, we have all heard of the atomic bomb and of course of Hiroshima, but never in as much detail or on such a personal level as these stories. Not even in chemistry or physics class, where I learned some of the specifics as to how the bomb works, had I known of the destructive force of the bomb or it's gruesome effects on human beings. As I mentioned ...
  • Force Of Attraction Between Gas Particles
    1,777 words
    Chapter 13- States of Matter Gases Kinetic Molecular Theory. Model to describe properties of gases. Kinetic = move. Theory describes behavior in terms of particles in motion. Model makes assumptions about size, motion, and energy of gas particles Particle size. Gases consist of small particles that are separated from one another by empty space. Because gas particles are far apart, there are no significant attractive or repulsive forces among them Particle Motion. Gas particles are in constant ra...
  • Importance Of Surface Tension In Liquids
    428 words
    During the movie we were able to understand the importance of surface tension in liquids that have open surfaces. Surface tension is a property of liquids that is described as a pulled that exists in liquid surfaces which is uniform in all directions. Surfaces act as if they are in tension; this tension force affects the shape and motion of liquids that have an open surface. The force is between molecules that repel each other when close to each other, and attract each other when they are far aw...
