Question

Which law of motion is also known as the Law of Acceleration?

• A. First
• B. Second
• C. Third
• D. Fourth

Hint:

Second law connects force and motion mathematically using \( F = ma \), making it the most practical law in problem-solving.

Answer 1

The Correct Option is B

Concept: Newton’s laws of motion describe the relationship between force and motion. The second law specifically relates force to acceleration.
Newton’s Second Law (Law of Acceleration): It states that the rate of change of momentum of a body is directly proportional to the applied force and occurs in the direction of the force. \[ F = ma \] where,
\( F \) = force
\( m \) = mass
\( a \) = acceleration
Explanation:
Greater force → greater acceleration.
For constant mass, acceleration is directly proportional to force.
Hence, it is called the Law of Acceleration.
\[ \boxed{\text{Answer: (B) Second Law}} \]
