The weight of the crate is acting downward on the ground and the ground is exerting a force equal to the weight of the crate upward on the crate.
The weight of the crate is acting downward on the ground and the ground is exerting a force equal to the weight of the crate upward on the crate.
The net force on a sliding crate is the vector sum of all forces acting on the crate. It is the force that is causing the crate to accelerate or decelerate. If all forces are balanced, the net force will be zero and the crate will move at a constant velocity.
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.
Gravity is a force acting down on it. A normal force is acting perpendicular to the ground at the base of the structure.

a girl and a boy are pulling heavy crate at the same time with 10 units of force each . what is the net force acting on ythe object?
If the crate isn't accelerating ... i.e. sliding at a constant speed, not speeding up or slowing down ...then the forces on it are balanced. The pseudo-force of friction is 140N in the direction opposite toits speed.
The crate will move to the left because the force to the left (25N) is greater than the force to the right (10N). The net force acting on the crate is the difference between the two forces: 25N (left) - 10N (right) = 15N to the left.
When a plane is still on the ground, the main forces acting on it are weight and normal force. Weight is the force due to gravity acting downward, while the normal force is the force exerted by the ground perpendicular to the plane to support its weight. Additionally, there may be frictional forces acting on the wheels to prevent the plane from moving.
The force of friction acting on a crate sliding across the floor is equal in magnitude but opposite in direction to the force applied to move the crate. It depends on the coefficient of friction between the crate and the floor, as well as the weight of the crate.
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.
When an airplane is still on the ground, the main forces acting on it are the gravitational force acting downwards and the normal force exerted by the ground acting upwards to support the weight of the airplane. There are typically no aerodynamic forces acting on the airplane until it starts moving.
