What else can I help you with?
What are some situations where friction is good and some some where friction is bad?
In situations where you want to create heat or dissipate kinetic energy, friction is usually a good thing. Friction when rubbing your hands together creates heat, which you appreciate, and friction between your brake pad and brake disc slows down your car, which is also a good thing. In situations where you want to maintain kinetic energy or minimize heat, friction is usually bad. Air friction slows down a glider, limiting its range, and mechanical friction in a car rolling on a flat surface causes it to stop without the brakes being applied.
How is friction good and bad?
Friction is good because it provides traction. Friction is necessary for people to stand, or for vehicles to accelerate or break. Friction can also be used to convert kinetic energy to heat or electrical energy. Friction can be bad because kinetic energy is can be lost to friction.
What friction deals with objects that are already moving?
friction acting on a such a body is called kinetic friction.here friction will try every thing that it can to stop the body.
Is kinetic friction the hardest friction to overcome?
No, static friction is generally stronger than kinetic friction.
Which type of kinetic fiction is usually greater sliding kinetic friction or rolling kinetic friction?
Sliding Kinetic Friction is usually greater than Rolling Kinetic Friction. Sliding Kinetic Friction is caused by two objects being dragged together, providing more opportunity for the objects' microscopic hills and valleys to catch.
What is kinetic friction and sliding friction?
Kinetic friction is the friction that arises between surfaces in relative motion. Sliding friction is the friction that occurs when an object slides over a surface.
How to calculate the coefficient of kinetic friction in a given scenario?
To calculate the coefficient of kinetic friction in a given scenario, you can divide the force of kinetic friction by the normal force acting on the object. The formula is: coefficient of kinetic friction force of kinetic friction / normal force.
What is the coefficient of kinetic friction between the 13.0kg wooden crate and the horizontal force of 31N of the floor?
The coefficient of kinetic friction can be calculated using the formula: coefficient of kinetic friction = force of kinetic friction / normal force. The force of kinetic friction can be found using the formula: force of kinetic friction = coefficient of kinetic friction * normal force. Given the force of 31N and normal force equal to the weight of the crate (mg), you can calculate the coefficient of kinetic friction.
What are the 2kinds of friction?
The two types of friction are static friction and kinetic friction. Static friction occurs when two surfaces are at rest relative to each other, while kinetic friction occurs when two surfaces are in motion relative to each other.
Why kinetic friction is less than sliding friction?
there is more surface area contact with kinetic friction as opposed to sliding friction
How is static friction and kinetic friction differ from each other?
Static friction occurs when an object is at rest on a surface, preventing it from moving. Kinetic friction occurs when an object is already in motion on a surface, resisting its motion. Static friction is usually stronger than kinetic friction.
Can the coefficient of static friction be equal to the coefficient of kinetic friction?
No, the coefficient of static friction is typically greater than the coefficient of kinetic friction.
