say mass(m) = 10 kg, radius(r) = 10 m, say friction coefficient = 0.5
force to break friction = 10 * 0.5 = 5 kgf = say 50 n
to find acceleration required to produce this force use f=m*a, shuffle to a = f / m
so a = 50 / 10 = 5 (m/s)/s, install in a = v^2 / r, so 5 = v^2 / 10,
so 10 * 5 = v^2, so sq. root 50 = v, so v = 7.07 metres / second
if friction coefficient and radius remain the same, altering the mass wont alter the velocity at breakaway point
Static friction can affect circular motion by providing the necessary force to keep an object moving in a circular path without slipping. It acts in the direction opposite to the motion of the object, preventing it from sliding out of the circular path. This frictional force helps maintain the object's velocity and direction in the circular motion.
When an object is moving at a constant velocity, it means that the forces acting on it are balanced. In this case, the force of kinetic friction is equal and opposite to the applied force, making it easier to calculate the coefficient of kinetic friction using the known values of force and normal force.
Friction can have an impact on velocity ratio by reducing the efficiency of a system. Friction can transfer energy into heat, causing a loss in velocity and making it more difficult to maintain a consistent velocity ratio. Reducing friction through lubrication or other means can help improve the velocity ratio.
To keep a block at a constant velocity, you need to apply a force equal in magnitude but opposite in direction to the force of friction acting on the block. This force is called the kinetic friction force and is dependent on the coefficient of friction between the block and the surface it's on.

The strength of the force of friction depends on the types of surfaces involved and on how hard the surfaces push together.
To calculate the friction in a pulley, you can use the formula: Friction = µ * N, where µ is the coefficient of friction and N is the normal force acting on the pulley. The coefficient of friction represents how "rough" the surfaces in contact are. By multiplying the coefficient of friction with the normal force, you can determine the amount of friction in the pulley system.

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.
The minimum rate of flow required to maintain the transportation of 1.0 centimeter diameter particles in water is typically around 0.15 meters per second. This is based on the Shields criterion, which determines the threshold for sediment movement in streams based on flow velocity and particle size.

The coefficient of friction is a scalar value with no dimension. It is simply a ratio of the force of friction between two objects, to the force pressing those objects together (often the normal force). Slippery surfaces have lower coefficient of friction than rough surfaces.
In circular motion, the velocity of an object is directly proportional to its radius. This means that the larger the radius, the greater the velocity needed to maintain the circular path. This relationship is described by the equation v = ωr, where v is the velocity, ω is the angular velocity, and r is the radius.
