Balance forces are two forces acting in opposite directions on an object, and equal in size. Anytime there is a balanced force on an abject, the object stays still or continues moving continues to move at the same speed and in the same direction.

The box is pushing weight on the table.

In physics, the Net force is the overall force acting on an object. To calculate net force, the body is isolated and interactions with the environment or other constraints are represented as forces and torques in a free-body diagram.

The book is moving with net force

Average speed can be viewed as the rate of change in distance with respect to time. A car traveling at an average speed of 25 miles per hour covers an average distance of 25 miles every hour.

For each mile there is a measurement of time.

Static friction is a force that keeps an object at rest. It must be overcome to start moving the object. Once an object is in motion, it experiences kinetic friction. If a small amount of force is applied to an object, the static friction has an equal magnitude in the opposite direction.

The guy is pulling the box with Static Friction.

Kinetic friction, also known as sliding friction or moving friction, is the amount of retarding force between two objects that are moving relative to each other.

The box will move with force.
