Air Resistance is a force that opposes the body's motion in free fall. Faster you fall greater the force is. Force Drag Equation is expressed using the formula F = k * v² Where v is the instantaneous speed and k is the air resistance coefficient measured in kg/m . ...
He used the equation Fnet=m∗a to describe the Second Law of Motion. Rearranging this expression to solve for a: a=Fnet/m, it is easier to see how air resistance represents one of the potential external forces influencing the rate of acceleration of an object. Isaac Newton, the British...
Calculating Air Resistance: Air resistance is usually calculated using the “drag equation”, which determines the force experienced by an object moving through a fluid or gas at relatively large velocity. This can be expressed mathematically as: In this equation,FDrepresents the drag force,pis the...
Last semester I did a project for grade 12 physics where I had to account for air resistance in projectile motion. I just wanted to post my solution here...
The resistive force on a sphere is calculated using the equation F = 1/2 * ρ * v^2 * A * Cd, where F is the resistive force, ρ is the density of the fluid, v is the velocity of the sphere, A is the cross-sectional area of the sphere, and Cd is the drag coefficient of ...
Step 2:Use the information given along with the equation for acceleration and identify which graph shows an object's acceleration as a result of air resistance. Using these values as well as the acceleration equation, we can see that...

Hardness can be defined as the resistance of a material to an applied pressure or force. Brinell hardness TheBrinell hardnessnumber is a number proportional to the load or test force of a hard steel ball to the calculated curved area of the indentation formed. The ball diameter is 1, 2.5,...
as compared with that in the lower airways, may moderate the penetration of ozone to the underlying cells and the resultant toxicity in the nasal passages as compared with the lung. Even in theabsenceof reaction, the mucus layer does exert diffusional resistance to uptake, which can be signific...
It was found the current density of the DAE using H2SO4 soaked melamine sponge could also reach 150 mA cm−2, 2.5 times higher than that using sintered glass foam, because the series resistance of the former was 50% lower owning to its high open-pore fraction (Fig.2e). However,...
