Sliding friction
Coefficient of rolling friction will always be less than that of sliding friction. Hence more force is required to overcome sliding friction. Because the force = coefficient of friction x normal force (ie weight of the body)
Static friction typically requires more force to overcome compared to kinetic friction because static friction opposes the initiation of motion between two surfaces, while kinetic friction opposes the relative motion of surfaces that are already moving against each other.
Sliding friction typically requires more force to overcome compared to rolling friction. Rolling friction occurs when an object rolls over a surface, which reduces the contact area and frictional force, while sliding friction involves two surfaces rubbing against each other with a larger contact area, resulting in higher resistance.
The type of friction between stationary objects that has more momentum than a car is static friction. Static friction occurs when two surfaces are not moving relative to each other but still exert a force in opposition to any impending motion. It requires more force to overcome static friction compared to kinetic friction.
No. It takes a force to put something in motion, and it takes force to stop it. To keep it moving requires zero force. If there is no opposing friction force, it will continue moving forever. If you can significantly reduce the friction, a small force can keep an object moving - just enough to counteract the force of friction.No. It takes a force to put something in motion, and it takes force to stop it.
