In which situation would the momentum of a moving object increase? (1 point)
Two forces of equal magnitude act on the object in opposite directions.
A new force acts on the object, opposing the object's motion.
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.
The momentum of a moving object would increase in the situation where a force acting in the direction opposite the object's motion is removed from the object.
The situation in which the momentum of a moving object would increase is when a force acting in the direction opposite the object's motion is removed from the object.
To determine in which situation the momentum of a moving object would increase, we need to understand the concept of momentum and how it is affected by forces.
Momentum is defined as the product of an object's mass and its velocity. Mathematically, momentum (p) can be expressed as p = m * v, where m is the mass of the object and v is its velocity.
According to Newton's second law of motion, the net force acting on an object is directly proportional to its rate of change of momentum. In other words, a force acting on an object will cause a change in its momentum.
Now let's analyze each situation mentioned:
1. Two forces of equal magnitude act on the object in opposite directions: In this case, since the forces are equal and opposite, they will cancel each other out, resulting in no net force acting on the object. As a result, the momentum of the object will not change. Therefore, the momentum would not increase in this situation.
2. A new force acts on the object, opposing the object's motion: When a force acts in the opposite direction of an object's motion, it opposes the object's velocity and slows it down. This force will cause a decrease in the object's momentum. Therefore, the momentum would not increase in this situation.
3. A force acting in the direction of the object's motion is removed from the object: When a force acting in the direction of an object's motion is removed, there will be a decrease in the net force acting on the object. As a result, the object will experience a smaller opposing force, allowing it to maintain or increase its velocity. Consequently, the momentum of the object will increase in this situation.
4. A force acting in the direction opposite the object's motion is removed from the object: When a force acting in the opposite direction to the object's motion is removed, the net force acting on the object will increase. As a result, the object will experience a larger net force in the direction of its motion, leading to an increased acceleration and therefore an increase in its momentum. Therefore, the momentum would increase in this situation.
Therefore, the correct answer is: "A force acting in the direction opposite the object's motion is removed from the object."
