Why is it easier to determine the coefficient of kinetic friction if the object moves with a constant velocity?

if moving with constant velocity the only force to slow it down is kinetic friction; if it is accelerating velocity is not constant and an additional force is being applied.

Does friction affects velocity ratio?
No. The velocity ratio remains constant but the friction absorbs power.
What is the difference between static friction and sliding friction?
Sliding friction is always less than the static friction by small amount.
How would the velocity of the book change if the applied force were equal to the sliding friction force?
The book slides with constant velocity.
How does the initial velocity change with he point of released of inclined plane?
the INITIAL velocity does not change. It is constant. however, the velocity changes depends on the friction and inclination of the inclined plane.
What is the average value of coefficient of velocity in a submerged orifice?
coefficient of velocity is 0.97 coefficient of discharge is varied from 0.80 to 0.64 coefficient of contraction is 0.64 thanks to me later .do your assignments

No. The velocity ratio remains constant but the friction absorbs power.
What does friction have to do with skydiving?
It determines your terminal velocity, depending on your drag coefficient.
What are the two factors that affect the friction force between two surfaces?
The strength of the force of friction depends on the types of surfaces involved and on how hard the surfaces push together.
How can you determine the speed of an object that has constant motion if you have a distance vs time graph of the motion?
If constant motion means constant velocity then, total distance / total time = avg velocity => avg speed constant velocity => avg velocity = velocity
What happens of there is no friction?
Objects would move with constant velocity or stay at rest.
What is the difference between static friction and sliding friction?
Sliding friction is always less than the static friction by small amount.
What is the coefficient of friction in a 6 inch round duct with a velocity of 200cfm?
0.32 in. H20 per 100 ft.
How would the velocity of the book change if the applied force were equal to the sliding friction force?
The book slides with constant velocity.
Why you never see objects moving with constant velocity unless a net force is applied?
friction
