What force is responsible for the painful difference between sliding on pavement and sliding on grass?
friction: the force that resists relative motion between two bodies in contact.
Wet pavement is more slippery than dry pavement because of force needed to overcome what friction is less than the force needed to overcome sliding friction?
On wet pavement, the presence of water reduces the friction between the tires and the road surface, making it more slippery. This is because the force needed to overcome static friction (needed to start moving) is less than the force needed to overcome sliding friction (needed to maintain motion). As a result, it is easier for a vehicle to slide or skid on wet pavement compared to dry pavement.
How do static friction and kinetic differ from each other?
Static friction is a force that must be overcome to start motion. Kinetic friction is the force that must be overcomne during motion or the motion stops.
What force is responsible for the painful difference between sliding on grass and sliding on pavement?
The force responsible for the painful difference between sliding on grass and sliding on pavement is primarily friction. Grass has more resistance and provides a softer landing surface, reducing the impact force compared to the harder and more abrasive surface of pavement. This difference in friction and surface roughness affects how energy is dissipated during a slide, leading to a less painful experience on grass compared to pavement.
Is friction a greater force when motion is faster?
Friction is not affected by the speed of motion. The force of friction remains constant regardless of the speed of the objects in contact.

Why is friction greater between surfaces that are rough?
the greater will strike opposing the motion

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 does the force pushing 2 surfaces together effect friction?
The force pushing two surfaces together increases the friction between them. The greater the force pressing the surfaces together, the greater the frictional force that resists relative motion between them.
Is the amount of friction greater between rough surfaces or smooth and Why?
The amount of friction is generally greater between rough surfaces because the irregularities on the surfaces create more points of contact and interlock, increasing resistance to motion. Smooth surfaces have less interlocking and contact points, resulting in lower friction.
True or false the force needed to overcome kinetic friction is useally greater than that needed to overcome static friction?
False. The force needed to overcome static friction is typically greater than that needed to overcome kinetic friction. Static friction is the resistance to motion when an object is at rest, while kinetic friction is the resistance to motion when an object is already in motion. Static friction requires more force to overcome because it is necessary to break the initial "stickiness" between the surfaces.
What is normally greater static friction or sliding friction on the same object?
Static friction is typically greater than sliding friction on the same object. Static friction is the force that must be overcome to start an object moving, while sliding friction is the force that resists the motion of an object already in motion.
Why the coefficient of static friction is greater thant the coefficient of kinetic friction?
The coefficient of static friction is typically greater than the coefficient of kinetic friction because it takes more force to overcome the initial resistance to motion (static friction) than to maintain the motion once it has started (kinetic friction). This is due to microscopic irregularities and interlocking between surfaces when at rest, which require a greater force to break compared to when they are already in motion.
