SUMMARY
Newton's Second Law states that force (F) is the product of mass (m) and acceleration (a), expressed as F=ma. In the context of two 1 kg objects, one traveling at 100 m/s and another at rest, the force is zero until they collide. Upon impact, a force is indeed involved due to the change in velocity, which can be classified as negative acceleration during deceleration. The mathematical relationship confirms that any change in velocity, whether an increase or decrease, results in a force acting on the object.
