2005年2月25日 · 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 …

2014年11月12日 · No. In general weight does not affect air resistance. Air resistance depends on shape. If both feathers are the same shape their drag properties ("air resistance") will be the …

2003年11月17日 · Air resistance can be calculated using the formula: Drag Force (D) = 0.5 × Drag Coefficient (Cd) × Air Density (ρ) × Velocity² (v²) × Cross-sectional Area (A). This formula …

2019年3月5日 · A marble rolls down an inclined plane with an angle of elevation of 5 degrees, roughly 4.9sin(5)m/s/s, and at normal pressure temperature NPT what would I need to add to …

2013年10月20日 · The coefficient of air resistance, or drag coefficient, is a measure of the resistance an object experiences as it moves through a fluid, in this case, air. The value of …

2009年9月12日 · In summary, the conversation discusses the effect of air temperature on air resistance and how it relates to the velocity of two balls dropped at the same time. The …

2017年1月18日 · Where air resistance does become relevant is in finding the value for $\kappa$ (torsion spring coefficient). Most of you will know that one can describe kappa with …

2010年5月4日 · In summary, the conversation discusses the problem of air resistance on a rotating cylinder and the equations used to describe the system. The initial drag equation is …

2014年3月24日 · When an object, such as a ball, is thrown upwards, it experiences both gravitational force and air resistance. The force of gravity pulls the ball towards the Earth, …

2007年5月20日 · 3. As you mentioned, air resistance and friction will definitely affect the period of a pendulum. In the presence of air resistance, the amplitude will gradually decrease due to the …
