What else can I help you with?
The force needed to overcome static friction is usually less than that needed to overcome kinetic friction?
true
The force needed to overcome kinetic friction is usually less than that needed to overcome static friction true or false?
False. The force needed to overcome static friction is usually greater than the force needed to overcome kinetic friction.
True or false when an object rolls over a surface the kind of friction that occurs is called round friction?
False. The type of friction that occurs when an object rolls over a surface is called rolling friction, not round friction. Rolling friction is caused by the deformation of the object and surface at the point of contact, which generates resistance that opposes the motion of the object.
Is it true or false that friction reduces the efficincy of a machine?
True. Friction causes resistance within a machine, leading to loss of energy in the form of heat. This decrease in efficiency can result in the machine requiring more energy input to overcome friction and perform its intended task.
Friction is a force that can make work easier true or false?
False. Friction is a force that resists motion, so it can make work more difficult rather than easier. Minimizing friction can help make work easier.

false it is rolling friction

Air resistance is the opposite of from friction true or false?
False. Air resistance is friction. A meteor coming in from space hits our atmosphere and glows brightly due to the airs friction.

True or false the force needed to overcome kenetiic friction is useally greater than that needed to overcome static friction?
False. The force required to overcome static friction is generally higher than the force needed to overcome kinetic friction. Static friction is the resistance to the initial movement of two objects at rest, while kinetic friction is the resistance to the motion of objects sliding against each other.
Does friction help to increase gas mileage?
False
True or false A parity error rarely causes the system to halt?
false it ALWAYS causes the system to halt
If Mechanical energy that has been lost to friction has actually been destroyed true or false?
False. Mechanical energy lost to friction is not destroyed; it is converted into other forms of energy, such as heat and sound. This conversion of energy accounts for the decrease in the total mechanical energy of a system when friction is present.
True or false if you slide a bag of groceries along a countertop you must first overcome rolling friction?
False. When sliding a bag of groceries, you are overcoming sliding friction, not rolling friction. Rolling friction occurs when a round object like a wheel rolls along a surface.
