I did this for a physics experiment. The average value I got for mew was 5.74 x 10^4. I'm not sure how accurate this is though. This was an average of the coefficients from the cart traveling both from left to right and right to left, and I found out that my track was indeed not as level as I had thought. Anyway, the average value I came up with seems to fit with my data, but it's important to remember that when the numbers get this small, the quality of the measuring devices stands out. My timers only went to the thousandths of a second and I'm not sure how accurate my measurements of distance were (possibly off by a tenth or more of a centimeter) and they could have changed without my noticing during the experiment. I found the value by taking an average velocity of a cart at two points, and then finding the average acceleration over the interval between the points , and then I was able to calculate the force of friction.
The coefficient of friction for air flow in a round duct is typically around 0.02. This coefficient may vary depending on factors such as surface roughness and airflow conditions.
for lifting the object there is no role of friction,but of air friction.since no info,. is given about it so air friction = 0.thereby for lifting we have mg = mass * 9.8 (the wight of the object). and for sliding we have 0.3*mg . therefore 0.7mg of more force is required to lift it.
Generally no. The friction force is typically assumed independent of surface area, and proportional to the force between the two objects. By changing the contact area, you are changing how that force is concentrated. i.e. a small surface area means that your force is distributed across a small region, creating a high pressure (force/area) at the contact. By increasing the surface area, you distrubte that force and lower the pressure. This is, however, an idealization and can break down in some instances.
Friction is the force that resists the relative motion between two surfaces in contact, while air resistance is the force that acts against the motion of an object as it moves through the air. Friction occurs between solid surfaces, while air resistance occurs when an object moves through a fluid medium like air.
Fluids can be air or liquids when referring to fluid friction. A paper airplane flying through air is acted on my by friction of the atmosphere. A submarine or ship moving below or above the sea is affected by the fluid friction of water. This because matter rubbing against matter cannot do so without resistance from friction.
Air and friction both being fluids, the resistive forces between them are more related to drag than friction.
The strength of the force of friction depends on the types of surfaces involved and on how hard the surfaces push together.

A linear Air track is an Equilateral Triangular Prism with lots of holes on 2 of the sides, at the one of the ends it is sealed and the other end has a fan. The Fan pumps air into the prism and the air leaves the holes, when you place something on top of it, usually on a 60 degree angle base, It will float. One tap and it goes flying.

An air track is used as a model for momentum because the air hovering beneath the track minimizes friction, allowing objects to move with almost no resistance. This setup allows for more accurate measurements of the conservation of momentum in collisions and interactions between objects.
A linear air track is typically used in the study of motion in physics. Depending of the different tracks available, different experiments can be conducted. These range from proving the conservation of momentum (m1*u1 + m2*u2 = m1*v1 + m2*v2), to finding the rate of acceleration (a = difference in velocity/difference in time).
The damping coefficient of a pendulum is a measure of how quickly the pendulum's oscillations dissipate over time due to external influences like air resistance or friction. A larger damping coefficient means the pendulum's motion will decay more rapidly, while a smaller damping coefficient means the motion will persist longer. The damping coefficient is typically denoted by the symbol "b" in the equation of motion for a damped harmonic oscillator.
Linear Air was created in 2004.
The coefficient of thermal expansion of air is approximately 0.00367 per degree Celsius.
