Let me work through these questions step by step.
Q.2 Analysis:
This question is about Newton's first law of motion, which states that an object will remain at rest or in uniform motion unless acted upon by an unbalanced force.
a) "An object at rest tends to stays ___" - Objects that are not moving tend to stay not moving (at rest). Answer:
at rest ✓
b) "An object in motion tends to stays ___" - Objects that are moving tend to keep moving. Answer:
in motion ✓
c) "An object acted upon by ___ stays at rest." - If forces are balanced (equal and opposite), they cancel out, so the object doesn't move. Answer:
balanced force ✓
d) "An object acted upon by ___ changes speed and direction." - Unbalanced forces cause acceleration, which means changes in speed or direction. Answer:
unbalanced force ✓
All answers shown in the image appear to be correct!
Q.3 Analysis:
The question asks for the term defined as "the tendency of objects to resist changes in their state of motion."
Let me check each option:
- a) Speed - This is how fast something moves, not resistance to change
- b) Inertia - This IS the definition of inertia: the tendency to resist changes in motion
- c) Force - This is a push or pull, not resistance to change
- d) Mass - While mass is related to inertia (more mass = more inertia), it's not the definition itself
The correct answer is
Inertia.

Final Answer:
Q.2: All answers are correctly filled in (at rest, in motion, balanced force, unbalanced force)
Q.3: b) Inertia
