Rectilinear or linear motion refers to the movement of a particle in a straight line, described along a single coordinate axis and time. This kind of motion can be seen in various real-life situations, such as the movement of a vehicle on a straight road or the trajectory of a bullet fired from a gun.
What is average velocity?
Average velocity (Vav) is the total displacement divided by the total time taken. It is calculated as (rf – ri) / ∆t.
What is the equation of motion for constant acceleration?
The equations of motion for constant acceleration are v=u + at, s= ut + ½ at^2, v^2 = u^2 + 2as, and s = {(u+v)/2}t.
What are the equations for a freely falling body?
For a freely falling body, the equations are v =-gt, s= -½ gt^2, v^2 = – 2gs, and sn = -g/2(2n-1).
