Let's go through each of the questions in your quiz and solve them one by one, with explanations.

1. An object at rest will stay at rest and an object in motion will stay in motion unless acted on by a force, is which one of Newton's Laws of Motion?
Answer: B) 1st Law of Motion
✔ Explanation:
This is Newton’s
First Law of Motion, also known as the
Law of Inertia. It states that an object will remain at rest or in uniform motion in a straight line unless acted upon by an external unbalanced force.

2. When an object resists change, like a body in a turning car, it is called _________.
Answer: C) inertia
✔ Explanation:
Inertia is the tendency of an object to resist changes in its state of motion. When a car turns, your body tends to continue moving in a straight line due to inertia — this is why you feel pushed to the side.

3. With unbalanced forces, the object will move in the direction of the _____ force.
Answer: A) larger
✔ Explanation:
When forces are
unbalanced, the net force determines the direction of motion. The object accelerates in the direction of the
larger (net) force. For example, if you push a box with more force than friction, it moves in the direction of your push.

4. Wheels on a skateboard most likely experience –
Answer: B) Rolling Friction
✔ Explanation:
The wheels of a skateboard
roll over the ground, so they experience
rolling friction, which is generally less than sliding or static friction. Rolling friction occurs when an object rolls over a surface without slipping.
-
Fluid friction → happens in liquids/gases (e.g., swimming)
-
Static friction → when surfaces are not moving relative to each other
-
Sliding friction → when two surfaces slide against each other
So,
B is correct.

5. Swimming fish experience –
(Although the image isn't fully visible, based on context and typical questions...)
Answer: A) Fluid Friction
✔ Explanation:
Fish swim through water, which is a fluid. The resistance they face from the water is called
fluid friction. This is the type of friction between an object and a fluid (liquid or gas) when moving through it.
