Physics · MOTION IN A STRAIGHT LINE

हिन्दी

Consider the following statements regarding kinematics equations and graphs: (A) The equation \( v = v_0 + at \) is valid only for constant acceleration. (B) The position-time graph for zero acceleration is a straight line parallel to the time axis. (C) Free fall near Earth's surface is an example of motion with uniform acceleration. (D) The velocity-time curve can have sharp instantaneous breaks in real physical scenarios. How many of the above statements are correct?

  1. A

    Only one

  2. B

    Only two

  3. C

    Only three 

  4. D

    All four

View Answer & Solution

Correct answer · Option B

Only two

Explanation

Statements (A) and (C) are correct. Statement (B) describes zero velocity (parallel to time axis), whereas zero acceleration means constant non-zero velocity slope. Statement (D) is false due to physical continuity.
