bodies in motion

Bodies in motion follow the principles of physics, primarily described by Newton's laws. An object will stay at rest or keep moving in a straight line at a constant speed unless acted upon by an external force. When force is applied, it changes the object's velocity—speed or direction. For example, pushing a shopping cart causes it to accelerate, while friction or resistance slows it down. These fundamental concepts explain how objects move, how forces influence motion, and are essential for understanding everything from everyday activities to complex systems.
