In which situation would the monumentum of moving object increase a force acting in the direction of the object's motion is removed from the object a force acting in the direction opposite the object's motion is removed from the object two forces of equal magnitude act on the object and opposite direction a new Force acts on the object opposing the object's motion
The situation in which the momentum of a moving object would increase is when a force acting in the direction of the object's motion is removed from the object.
The situations in which the momentum of a moving object would increase are:
1. When a force acting in the direction of the object's motion is removed from the object: If a force that was previously pushing the object in the direction of its motion is suddenly removed, the object will continue to move with its initial momentum, resulting in an increase in momentum.
2. When a force acting in the direction opposite to the object's motion is removed from the object: If a force that was opposing the object's motion is suddenly removed, the object will experience a decrease in resistance, allowing it to increase its velocity and therefore its momentum.
3. When two forces of equal magnitude act on the object in opposite directions: If two equal and opposite forces act on the object, the net force acting on it would be zero. In this case, the object would continue moving with its initial momentum, resulting in an increase in momentum.
4. When a new force acts on the object opposing the object's motion: If a force is applied to the object that opposes its motion, but the object is able to overcome this resistance and continue moving, its velocity and momentum would increase.
To determine in which situation the momentum of a moving object would increase, let's analyze each scenario you listed:
1. When a force acting in the direction of the object's motion is removed from the object:
- According to Newton's first law of motion, an object in motion will continue moving in a straight line with a constant speed unless acted upon by an external force. In this case, when the force acting in the direction of motion is removed, the only force acting on the object is now absent. Consequently, the object will tend to maintain its current state of motion, and its momentum would remain unchanged.
2. When a force acting in the direction opposite to the object's motion is removed from the object:
- Similar to the previous scenario, removing a force acting in the direction opposite to the object's motion would result in the absence of any external force on the object. As a result, the object would still tend to maintain its current state of motion, and its momentum would not increase.
3. When two forces of equal magnitude act on the object in opposite directions:
- If two forces of equal magnitude act on the object in opposite directions, the forces would cancel each other out, resulting in a net force of zero. When the net force is zero, the object experiences balanced forces, and its momentum would remain the same.
4. When a new force acts on the object opposing the object's motion:
- In this scenario, a new force is added to the object, opposing its motion. The momentum of the object can only increase if the force applied is greater than the opposing force to overcome it. If the new opposing force is smaller than the force previously causing the object's motion, the momentum of the object would increase in the opposite direction.
In summary, the only situation where the momentum of a moving object would increase is when a new force acts on the object opposing its motion, but the magnitude of the new force is greater than the opposing force.
