For a body moving with non-uniform velocity and uniform acceleration

For a body moving with non-uniform velocity and uniform acceleration 

(1) Displacement – Time graph is linear 

(2) Displacement – Time graph is non-linear 

(3) Velocity – Time graph is non-linear 

(4) Velocity – Time graph is linear 


Answer: (2) Displacement-time graph is non-linear. Linear motion (also called a rectilinear motion) is moving along a straight line, and can therefore be described mathematically using only one spatial dimension. The linear motion can be of two types: uniform linear motion with constant velocity or zero acceleration; non-uniform linear motion with variable velocity or non-zero acceleration. The motion of a particle (a point-like object) along a line can be described by its position, which varies with (time). An example of linear motion is an athlete running 100m along a straight track. Linear motion is the most basic of all motion.
