RRB ALP-Speed and Velocity

Displacement ✘ Velocity ✘ Time ✘ None of these. ✔

parabola ✘ ellipse ✘ hyperbola ✘ straight line ✔

its acceleration is minimum ✘ its velocity is zero and its acceleration is also zero ✘ its velocity is zero but its acceleration is maximum ✘ its velocity is zero and its acceleration is the acceleration due to gravity. ✔

square of the initial velocity ✘ square of the initial acceleration ✘ the initial velocity ✘ the initial acceleration ✔

straight line ✘ circle ✘ parabola ✘ ellipse ✔

parabola ✘ ellipse ✘ hyperbola ✘ straight line ✔

uniform motion ✘ free fall ✘ non uniformly accelerated motion ✘ None of these ✔

The motion of an object along a straight line is a rectilinear motion ✘ The speed in general is less than the magnitude of the velocity ✘ The slope of the displacement-time graph gives the velocity of the body ✘ The area under the velocity-time graph gives the displacement of the body ✔

uniform velocity ✘ uniform acceleration ✘ variable acceleration ✘ constant momentum ✔

velocity is constant ✘ velocity varies non-uniformly ✘ acceleration is constant ✘ acceleration changes continuously ✔
