According to Newton's First Law of Motion, if no external force is acting upon a moving object, it will continue to move at a constant velocity. Therefore, the correct answer is:
It moves at a constant velocity.

How does Newton's First law explain the motion of an object in the absence of external forces?
*
1 point
The object always moves at a constant velocity
The object always remains at rest
The object always accelerates
The object always changes direction

Newton's First Law states that an object at rest will stay at rest and an object in motion will stay in motion at a constant velocity, unless acted upon by a net external force. Therefore, in the absence of external forces, the correct explanation for the motion of an object is:
The object always moves at a constant velocity.
Which direction will the box move in the diagram below?
5 N
3N
The box will move to the left
The box will move to the right
The box will not move at all
5 N
3N
The box will move to the left
The box will move to the right
The box will not move at all
To determine the direction the box will move, we need to look at the net force acting on it. If the box has a 5 N force acting to the right and a 3 N force acting to the left, we calculate the net force:
- Right force: +5 N
- Left force: -3 N
Net force = 5 N (right) - 3 N (left) = 2 N (to the right)
Since the net force is 2 N to the right, the box will move to the right.
So the correct answer is:
The box will move to the right.

To determine the net force acting on the object, we need to know the direction of the forces acting on it. Since you provided two forces, both listed as "5 N," but did not specify their directions, let's consider two scenarios:
-
If both forces are acting in the same direction (to the right, for example):
- Net force = 5 N + 5 N = 10 N (in the direction of the forces)
-
If the forces are acting in opposite directions (one to the right and one to the left):
- Net force = 5 N - 5 N = 0 N (the forces cancel each other out)
Since the problem doesn't specify the directions of the forces, the net force could either be 10 N (if they're in the same direction) or 0 N (if they're in opposite directions).
If you provide the directions of the forces, I can give you a more precise answer!
