COMEDK2025PhysicsMotion in One DimensionActual
Select the graph which represents the motion of a particle along a straight line with uniform acceleration.
Correct answer
2
Step-by-step solution
For a particle moving in a straight line with uniform acceleration a , the velocity v at time t is given by the equation v = u + at , where u is the initial velocity. If the particle starts from rest ( u = 0 ), the equation becomes v = at . This represents a linear relationship between velocity and time, which is a straight line passing through the origin with a slope equal to the acceleration a . Among the given options, the third graph shows a velocity-time graph that is a straight line passing through the origin
