Which statement about Newton's second law of motion is true?


A
Acceleration only depends on mass

B
Acceleration only depends on the amount of force applied

C
Acceleration depends on mass and amount of force applied

D
Acceleration does not depend on mass or amount of force applied

The correct answer is:

**C. Acceleration depends on mass and the amount of force applied**

### Explanation:
Newton's second law of motion states that the acceleration (\(a\)) of an object is directly proportional to the net force (\(F\)) acting on it and inversely proportional to its mass (\(m\)). Mathematically, this is expressed as:

\[
F = ma \quad \Rightarrow \quad a = \frac{F}{m}
\]

This means that:
- If the **force** increases while the mass remains constant, the **acceleration** will increase.
- If the **mass** increases while the force remains constant, the **acceleration** will decrease.

Thus, acceleration depends on **both** the force applied and the mass of the object.

### Tip:
Remember, if no net force is acting on an object, its acceleration is zero, meaning the object will either remain at rest or continue to move at a constant velocity (as per Newton's first law).
