While the box is moving in a straight line at a constant speed, the push only has to
overcome the kinetic friction.
Whatever the speed is, and whatever the weight of the box is, 4 pounds of push
IN THE DIRECTION THE BOX IS MOVING will keep this one going.
If the crate is moving at a constant velocity, then the force of friction acting on the crate is equal in magnitude and opposite in direction to the force you are applying to push the crate. This means that the force you apply to push the crate is balancing out the force of friction acting against it. By measuring the force you are exerting and observing the constant velocity of the crate, you can infer the magnitude of the friction force.
The force of friction would also be 1 N, equal in magnitude but opposite in direction to the force you are pushing with. This equal and opposite force of friction is what allows the book to move at a constant velocity.
Pushing requires overcoming static friction, which is usually stronger than kinetic friction (encountered when pulling). When pushing an object, you are initially having to overcome this static friction, making it feel harder. When pulling, you are already in motion so only kinetic friction needs to be overcome.
If the crate is moving at a constant velocity, the friction force is equal in magnitude but opposite in direction to the pushing force, so it is also 100 N. This is because the two forces are balanced and there is no net force acting on the crate.
The type of friction pushing a box along the floor is kinetic friction. This frictional force opposes the motion of the box and arises between the box and the floor due to their contact and relative motion.

An object maintains a constant velocity when the net force acting upon that object is zero. Therefore, a force pushing against the object that exactly opposes the force(s) due to friction (in both magnitude and direction) will result in a net force of zero, and the object will maintain a constant speed.

The type of friction pushing a box along the floor is kinetic friction. This frictional force opposes the motion of the box and arises between the box and the floor due to their contact and relative motion.
An example of sliding kinetic friction is pushing a box across the floor. As the box moves, there is friction between the box and the floor opposing its motion. This friction force must be overcome by applying a force in the direction of motion.
The two types of friction are static friction and kinetic friction. Static friction occurs when two surfaces are in contact but not moving relative to each other, while kinetic friction occurs when two surfaces are in contact and are moving relative to each other. An example of static friction is pushing a heavy box that is initially at rest, while an example of kinetic friction is dragging that same box once it is in motion.
The friction that occurs when pushing an object along the floor is kinetic friction. This type of friction acts in the direction opposite to the motion of the object and arises due to the contact between the object and the surface it is moving on.

Jumping involves kinetic friction between your feet and the ground when pushing off and static friction when your feet are in contact with the ground to generate an upward force. Additionally, there is air resistance acting against your movement as you jump.
Types of friction include static friction (sliding), kinetic friction (rolling), and fluid friction (fluid). Examples of sliding friction include pushing a heavy box across the floor, rolling friction is experienced when a ball rolls on the ground, and fluid friction occurs when swimming in water.
