    ap_cycles. Jul 5, 2010. Air Air resistance increase Resistance Speed. In summary: However, in summary, when a body falls through the air, more air molecules are displaced due to air resistance. This increased resistance is proportional to the surface area of contact. Jul 5, 2010.

  3. Deceleration of a projectile (With air resistance) - Physics...

    www.physicsforums.com/threads/deceleration-of-a-projectile-with-air-resistance...

    The deceleration of a projectile with air resistance can be calculated using the equation: a = (F - F air) / m, where a is the deceleration, F is the force applied to the projectile, F air is the force of air resistance, and m is the mass of the projectile. It is important to note that this equation is an approximation and may not account for ...

    In summary, air resistance can be proportional to either velocity or velocity squared, represented by the equation dV/dt=kv. The constant k varies depending on the shape and texture of the object, with a typical value of 0.5 for a spherical object like a baseball. There are also tables available for reference when calculating this constant.

    Nov 18, 2008. Air Air resistance Ball Resistance. In summary, when air resistance is present, a ball thrown vertically upward will return to its original level with less speed due to the conservation of energy principle. Air resistance uses up some of the ball's kinetic energy, causing it to return with less speed than its initial throwing speed.

    In any case, adding air resistance is not too difficult- the equation to solve is: m ds/dt - D*s = -mg, where D is the drag coefficient (6*pi*R*viscosity) for low Reynolds numbers. s = dv/dt. Neglecting air resistance, the way to solve the problem is: m d^2r/dt^2 = -mg, or m ds/dt = -mg which resolves to. m x = c*t.

  7. Does air temperature affect air resistance? - Physics Forums

    www.physicsforums.com/threads/does-air-temperature-affect-air-resistance.336624

    Air temperature can affect the flight of airplanes as it impacts air density and, therefore, air resistance. Hotter temperatures result in less air resistance, allowing airplanes to fly more easily and efficiently. However, extreme temperatures can also affect the performance of an airplane's engines and other components.

  8. How does weight affect air resistance? - Physics Forums

    www.physicsforums.com/threads/how-does-weight-affect-air-resistance.781315

    Gravity is a major factor in understanding how weight affects air resistance. Gravity is the force that pulls objects toward the Earth, and it is what causes objects to fall through the air. The greater the weight of an object, the stronger the force of gravity pulling it down, and therefore the more air resistance it will experience.

  9. Air resistance on rotating cylinder - Physics Forums

    www.physicsforums.com/threads/air-resistance-on-rotating-cylinder.333995

    Air resistance can affect a rotating cylinder by slowing it down and causing it to lose energy. This is due to the friction between the air molecules and the surface of the cylinder, which creates a resistance force that opposes the motion of the cylinder. 3.

  10. Newton's third law and air resitance? - Physics Forums

    www.physicsforums.com/threads/newtons-third-law-and-air-resitance.342212

    When an object moves through the air, it experiences air resistance. According to Newton's third law, this means that the air is also exerting an equal and opposite force on the object. This force of air resistance is what causes objects to slow down and eventually come to a stop when moving through the air. 3.

    Dec 6, 2012. Air Air resistance Analysis Confusion Dimensional analysis Resistance. In summary, air resistance is a force that opposes the motion of a falling body, and it is proportional to the velocity of the body. The force equation is F=ma, but air resistance is independent of velocity. Introductory material uses v not because it is correct ...
