26. An object experiences no acceleration. Which of the following cannot be true for the object? 0/1 No forces act on the object A zero net force acts on the object A single force acts on the object More than one force act on the object
Question
- An object experiences no acceleration. Which of the following cannot be true for the object? 0/1 No forces act on the object A zero net force acts on the object A single force acts on the object
More than one force act on the object
Solution
The statement that cannot be true for the object is "No forces act on the object".
Here's why:
-
"No forces act on the object" - This cannot be true because even if an object is not accelerating, it does not mean that no forces are acting upon it. For example, gravity is a force that acts on all objects regardless of whether they are accelerating or not.
-
"A zero net force acts on the object" - This can be true. According to Newton's First Law of Motion, an object at rest or moving at a constant velocity will continue to do so unless acted upon by a net external force. So, if the net force is zero, the object will not accelerate.
-
"A single force acts on the object" - This can also be true. If a single force acts on an object and it is balanced (i.e., there is no other force to counteract it), the object will not accelerate.
-
"More than one force act on the object" - This can be true as well. If multiple forces act on an object but they are balanced (i.e., they cancel each other out), the object will not accelerate.
