It's important to clarify that forces don't actually "go through" objects. Forces are interactions between objects, and they can act upon objects without directly passing through them.

Here's a breakdown of why we say this:

* Forces are interactions: A force isn't a tangible thing that travels. It's the result of one object influencing another. For example, gravity is a force that acts between Earth and a falling apple. The apple doesn't have gravity "going through" it; it's the interaction between the apple and Earth's mass that causes the force of gravity.

* Forces can cause changes in motion: A force can change an object's speed, direction, or shape. When you push a box, you apply a force that causes the box to move.

* Forces act on objects: A force always involves two objects. The object exerting the force and the object experiencing the force. For example, when you push a wall, you apply a force to the wall, but the wall also applies an equal and opposite force back on you.

Experiments demonstrating force interactions:

1. Pushing a box: Push a box across the floor. You're applying a force to the box, causing it to accelerate. The force you exert is acting on the box, but it doesn't pass through it.

2. Magnet and metal objects: Bring a magnet near a metal object. The magnet exerts a force on the metal, pulling it closer. Again, the force is an interaction between the magnet and the metal, not something that goes through the object.

3. Dropping a ball: When you drop a ball, gravity acts on it, causing it to accelerate downwards. This is an interaction between the ball and Earth's mass, not a force going through the ball.

Conclusion:

While forces can cause changes within objects, they don't literally "go through" them. Forces are interactions that occur between objects, and they are responsible for changes in motion, shape, and other properties.
