Question

There are 4 words given below. 3 of them are similar and can be classified into a group. Which of these words form a group?
Acceleration
Deceleration
Speed
Velocity

• A. 1,2 and 3
• B. 1,3 and 4
• C. 2,3 and 4
• D. 1,2 and 4

Answer 1

The Correct Option is D

Analysis of Terms Related to Motion and Dynamics 

Step 1: Explanation of Terms

“Acceleration”, “Deceleration”, and “Velocity” are all terms related to motion and dynamics. Acceleration and deceleration refer to the rate of change of velocity, while velocity refers to the speed of something in a given direction.

Step 2: Analyze the Term "Speed"

“Speed” is a measure of how fast something moves, but it doesn’t specifically relate to the rate of change of velocity, which is the focus of the other three terms.

Conclusion:

Therefore, the correct group consists of Acceleration, Deceleration, and Velocity.

Final Answer:

The correct answer is (1, 2, and 4): Acceleration, Deceleration, and Velocity.
