Is this Newton's first law second Law or third law a ball is rolling straight across the floor until Bradley kicks it
This scenario involves Newton's first law of motion. Newton's first law states that an object at rest will stay at rest, and an object in motion will stay in motion with the same speed and in the same direction unless acted upon by an external force. In this case, the ball is rolling straight across the floor, maintaining its motion, until Bradley kicks it.
The scenario you described involves Newton's first law, also known as the law of inertia. This law states that an object at rest will stay at rest, and an object in motion will stay in motion with the same speed and direction unless acted upon by an external force. The ball rolling straight across the floor represents an object in motion, and when Bradley kicks it, he applies an external force that changes its speed or direction, obeying Newton's first law.
The situation you described involves Newton's second law of motion.
Newton's first law, also known as the law of inertia, states that an object at rest will stay at rest, and an object in motion will stay in motion with the same speed and in the same direction, unless acted upon by an external force. This law does not directly apply to the scenario you mentioned because the ball is already rolling and in motion.
Newton's third law, known as the law of action-reaction, states that for every action, there is an equal and opposite reaction. This law pertains to the forces between two interacting objects. In the case of the ball rolling across the floor, the kicking action by Bradley will indeed create a reaction force on the ball, but that alone is not the main principle at play.
On the other hand, Newton's second law of motion is most relevant to this scenario. It states that the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass. In other words, the more force applied to an object, the greater its acceleration will be, and the greater its mass, the slower its acceleration will be. In this case, when Bradley kicks the ball, he applies a force to it, resulting in a change in its motion (acceleration).
To calculate the exact change in the ball's motion, you would need to know the magnitude of the force applied by Bradley, the mass of the ball, and any other factors affecting the motion, such as friction between the ball and the floor.
