Kinetic friction is actually the frictional force that opposes the motion of an object already in motion. It occurs when two surfaces are in contact and sliding past each other. The force required to start an object moving from rest is called static friction.

false. Kinetic friction is the friction acting upon a moving object. It would be the frictional force against you if you pulled a box across a table. Static friction is the frictional force needed to overcome to get an object at rest into motion.
The normal force can be calculated using the equation: Normal force = Weight - Kinetic frictional force. Given that the kinetic frictional force is 40 N, the normal force depends on the weight of the object and additional information is needed to calculate it.

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.

Static friction and kinetic friction are the two types of frictional forces that act to prevent or slow down motion. Static friction occurs when an object is at rest, while kinetic friction occurs when the object is in motion. Both types of friction oppose the relative motion of two surfaces in contact.
Static friction is the frictional force needed to overcome the initial resistance of an object at rest and set it in motion. This force is required to counteract the initial inertia of the object and is called static friction because it acts when an object is stationary.
Kinetic friction is independent of the weight of the object. It is determined by the nature of the surfaces in contact and the force pressing them together. The weight of the object affects the normal force, which in turn affects the frictional force, but the coefficient of kinetic friction remains constant for a given surface.
The frictional force needed to start an object at rest into motion is the static frictional force. This force must be overcome by an external force before the object can start moving. Once the object is in motion, the kinetic frictional force will oppose its movement.
