An object at rest remains at rest. An object in motion remains in motion unless acted upon by an outside force. This describes which of Newton’s Laws of Motion?(1 point) Responses Second Law of Motion Second Law of Motion Second and Third Laws of Motion Second and Third Laws of Motion First Law of Motion First Law of Motion First and Third Laws of Motion
This statement describes Newton's First Law of Motion, also known as the law of inertia.
The description "An object at rest remains at rest. An object in motion remains in motion unless acted upon by an outside force" corresponds to Newton's First Law of Motion, also known as the Law of Inertia.
To determine this, you can recall Newton's three laws of motion and identify which law matches the given description.
- Newton's First Law of Motion states that an object will stay at rest or continue moving in a straight line with a constant speed unless an external force acts upon it. This aligns with the provided description.
- Newton's Second Law of Motion relates force, mass, and acceleration, and it does not directly address objects staying at rest or in motion.
- Newton's Third Law of Motion states that for every action, there is an equal and opposite reaction. It also does not address objects staying at rest or in motion.
Therefore, the correct answer is: First Law of Motion.
Question Suppose 25 children who weigh the same are playing a game of tug-of-war. Five children pull with 10 newtons of force, while ten children pull with 15 newtons of force in the opposite direction. How can one determine the net force on the rope?(1 point) Responses The forces are in opposite directions, so the newtons can be divided. The forces are in opposite directions, so the newtons can be divided. The forces are in opposite directions, so the newtons can be subtracted. The forces are in opposite directions, so the newtons can be subtracted. The forces are in the same direction, so the newtons can be added. The forces are in the same direction, so the newtons can be added. The newtons are in the same direction, so the newtons can be multiplied. The newtons are in the same direction, so the newtons can be multiplied.
To determine the net force on the rope when 25 children are playing tug-of-war, you need to consider the forces acting in opposite directions.
In this scenario, five children pull with 10 newtons of force in one direction, and ten children pull with 15 newtons of force in the opposite direction.
To find the net force, you subtract the force in one direction from the force in the opposite direction since they are acting in opposite directions.
Therefore, the correct answer is: The forces are in opposite directions, so the newtons can be subtracted.
