Force and motion are fundamental concepts in physics that describe how objects interact and move. A force is any influence that can change the motion of an object, while motion refers to the change in position of an object over time. These concepts are essential for understanding the behavior of everything from everyday objects to celestial bodies. When a force is applied to an object, it can cause it to accelerate, decelerate, or change direction. The relationship between force, mass, and acceleration is described by Newton's Second Law, which states that the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass.
