False. The force needed to overcome static friction is usually greater than the force needed to overcome kinetic friction.
True -It's "False"!
True -It's "False"!
No, the force needed to overcome static friction is generally greater than the force needed to overcome kinetic friction. Static friction occurs when two surfaces are at rest relative to each other, requiring more force to overcome the initial "sticking" friction. Once the surfaces are in motion, kinetic friction occurs and typically requires less force to maintain motion.
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.
False. The force needed to overcome static friction is usually greater than the force needed to overcome kinetic 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.
Yes, that is correct. It generally requires more force to overcome kinetic friction (friction between moving surfaces) than static friction (friction between stationary surfaces). Once an object is in motion, the frictional force decreases, making it easier to keep the object moving compared to starting it from rest.
Kinetic friction is typically less than static friction because the surfaces are already in motion when kinetic friction is acting, so less force is needed to overcome the resistance between the surfaces. In contrast, static friction must be overcome to initiate motion, requiring a greater force.
True -It's "False"!
Kinetic friction is less than limiting friction because kinetic friction occurs once an object is already in motion, and the surfaces are sliding past each other, causing less resistance compared to the static friction that exists before the motion starts. Limiting friction is the maximum friction force that must be overcome to start an object moving, so it is typically higher than kinetic friction.
The force needed to keep the box moving at a constant velocity of 8 m/s would be equal to the kinetic friction force, which is 4 lb in this case. Therefore, a pushing force of at least 4 lb would be required to overcome the kinetic friction and maintain the constant velocity.
Actually, kinetic friction is the frictional force that opposes the motion of an object already in motion. The frictional force required to start an object at rest into motion is called static friction.
