* Weight vs. Force: Weight is the force of gravity acting on an object's mass. It always acts vertically downwards. A horizontal force acts perpendicular to weight.
* Friction: The key factor is friction. For the body to move, the applied horizontal force must overcome the force of friction between the body and the surface it's resting on.
* Static Friction: If the applied horizontal force is less than the maximum static friction, the body will not move. Static friction is the force that prevents a body from moving when at rest.
* Kinetic Friction: If the applied horizontal force exceeds the maximum static friction, the body will start moving. The friction then becomes kinetic friction, which is usually less than static friction.
Example:
Imagine pushing a heavy box on a floor. Even though the box is heavy (has a large weight), you can still move it with a relatively small horizontal force if the floor is smooth (low friction).
In summary:
* A horizontal force less than the body's weight can move the body if it exceeds the force of friction.
* The ability to move depends on the specific values of the applied force, the weight, and the friction coefficient between the body and the surface.
