If it's constant velocity, what's the acceleration? What is the relationship between acceleration and net force?Leedle said:Homework Statement
in the question you're having to solve for this.
A force is applied at a angle of 30 degrees on a object that weighs 12kg that is also moving at a constant velocity. kinetic friction is equal to .70
i am confused on how to find the Force applied to achieve a constant velocity

Yes it does. What do you think constant velocity means?Leedle said:It doesn't give it's acceleration
what i mean is that it doesn't give its acceleration as far as numbers wiseharuspex said:Yes it does. What do you think constant velocity means?
Yes it does! What does constant velocity mean??Leedle said:what i mean is that it doesn't give its acceleration as far as numbers wise
OMG sorry i just had a brain fart it's zero that's how working on a lot of things at once can confuse yourself it's acceleration is 0.haruspex said:Yes it does! What does constant velocity mean??
Happens to us all. Have a good day.Leedle said:OMG sorry i just had a brain fart it's zero that's how working on a lot of things at once can confuse yourself it's acceleration is 0.
Kinetic friction is the force that resists the motion between two surfaces that are in contact with each other. It is also known as sliding friction or dynamic friction.
Kinetic friction occurs when two surfaces are already in motion, while static friction occurs when two surfaces are at rest and attempting to move against each other. Kinetic friction is generally lower than static friction.
Kinetic friction is calculated by multiplying the coefficient of kinetic friction (μk) by the normal force (N) between the two surfaces. The formula is Fk = μkN, where Fk is the force of kinetic friction.
The value of kinetic friction depends on several factors, including the types of materials in contact, the roughness of the surfaces, and the force pressing the surfaces together (normal force). Other factors such as temperature and surface area also play a role.
Kinetic friction can be reduced by using lubricants between the two surfaces, making the surfaces smoother, or reducing the normal force between the surfaces. Additionally, using materials with lower coefficients of friction can also decrease the value of kinetic friction.
