Question

1. when forces are not equal, the object will be ______. 10. a force diagram uses to show the direction and strength of forces

Explanation:

Question 9

In physics (a subfield of Natural Science), when the net force on an object is not zero (forces are not equal in a way that they cancel out), the object will accelerate (change its velocity, which can be a change in speed, direction, or both) or be in a state of unbalanced force leading to motion change. The key concept here is Newton's second law which relates net force to acceleration ($F = ma$). So when forces are not equal (resulting in a non - zero net force), the object will accelerate (or be in motion with changing velocity, or be unbalanced and move). A common term used here is "accelerated" or "in motion" or "unbalanced" but the most precise term related to the effect of unbalanced forces is that the object will accelerate (or be in a state of motion with changing velocity, or be in an unbalanced state leading to acceleration).

In physics, a force diagram (free - body diagram) is a graphical representation. Arrows are used where the direction of the arrow shows the direction of the force and the length of the arrow (or sometimes the size of the arrowhead or other visual cues) represents the strength (magnitude) of the force.

Answer:

accelerated (or in motion, or unbalanced - the most accurate term based on physics concepts is that the object will accelerate as per Newton's second law when net force is non - zero)

Question 10

The image of question 10 is incomplete. But based on the context of force diagrams, a force diagram (free - body diagram) uses arrows to show the direction and strength (magnitude) of forces. The length of the arrow represents the magnitude (strength) of the force and the direction of the arrow represents the direction of the force.
If we assume the question is "A force diagram uses ______ to show the direction and strength of forces", the answer would be:
