Question
Which of the following could not be caused by a resultant force acting on an object?The object speeds upThe object maintains constant velocityThe object slows downThe object changes direction
Solution
The option "The object maintains constant velocity" could not be caused by a resultant force acting on an object.
Here's why:
-
A resultant force is a single force that has the same effect on an object as all the individual forces acting on it combined.
-
According to Newton's first law of motion, an object will maintain its state of motion unless acted upon by a net external force. This means that if an object is at rest, it will stay at rest, and if an object is moving at a constant velocity, it will continue to move at that constant velocity, unless a net external force acts on it.
-
If a resultant force is acting on an object, it means there is a net external force, and therefore the object cannot maintain its current state of motion. It will either speed up, slow down, or change direction.
-
Therefore, if an object is maintaining a constant velocity, it means there is no resultant force acting on it.
