No, it CAN'T be greater, and it is usually smaller.
False. The force needed to overcome static friction is usually greater than the force needed to overcome kinetic 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.

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.

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.
true
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.
The kinetic friction coefficient is a measure of the resistance between two surfaces in motion. A higher coefficient means more force is needed to overcome the friction and keep the surfaces moving.

As a rule, sliding friction is greater to overcome than fluid friction. However, the variables could be manipulated to show it in both lights. The mass, weight, surface area, types of surfaces, speed, ect... are all variables in which the amount of force is needed to overcome sliding friction. While density and viscosity are major variables in fluid friction.
By my understanding, this is due to the fact that it is easier to keep a moving object in motion than it is to accelerate it from a resting position. When a force is exerted on a stationary object, acceleration relies on that force alone. However, with a moving body, the momentum of the object reduces the force needed to overcome friction.
