When moving objects collide, a fundamental interaction occurs: each object pushes the other.
The Interaction During a Collision
According to physics principles and as stated in materials discussing collisions between objects, the defining characteristic of a collision is the mutual exertion of force. When two objects come into contact during a collision, they don't just passively interact; they actively influence each other through forces.
This means that:
- The first object exerts a force on the second object.
- Simultaneously, the second object exerts an equal and opposite force on the first object.
This reciprocal pushing action changes the motion of both objects involved.
A Practical Example
Think about a common scenario:
- Hitting a softball with a bat.
- As the reference explains, "The bat collides with the ball and pushes it away." This shows the bat exerting a force on the ball, changing its direction and speed.
- Crucially, "The ball also exerts a force on the bat." This force, though often less noticeable to the person swinging, contributes to the bat's recoil or change in swing dynamics.
In essence, a collision is a moment of intense mutual pushing or forcing between objects.
