A force acts on an object. which option describes an action that could prevent the object from moving?
a a force applied in the opposite direction with the same magnitude at the same time
b a force applied in the same direction with a greater magnitude at the same time
c a force applied in the same direction with the same magnitude at the same time
d a force applied in the opposite direction with a greater magnitude at the same time
d a force applied in the opposite direction with a greater magnitude at the same time
The correct option that describes an action that could prevent the object from moving is:
d) a force applied in the opposite direction with a greater magnitude at the same time.
To determine which option describes an action that could prevent the object from moving, we need to consider Newton's laws of motion.
Newton's First Law states that an object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an external force.
In this scenario, we have a force acting on the object, which means we need to apply an external force to counteract it. According to Newton's First Law, the force required to prevent the movement of the object should be equal in magnitude and opposite in direction to the force acting on it.
Therefore, the correct option would be:
a. A force applied in the opposite direction with the same magnitude at the same time.
By applying a force in the opposite direction with the same magnitude, the two forces would cancel each other out, resulting in a net force of zero on the object. As a result, the object would remain at rest and not move.
