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. Only one

  2. Only two

  3. Only three 

  4. All four

Correct answer · Option 2

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.
