Symmetric teleparallel gravity is an exceptional theory of gravity that is consistent with the vanishing affine connection. This theory is an alternative and a simpler geometrical formulation of general relativity, where the nonmetricity Q drives the gravitational interaction. Our interest lies in exploring the cosmological bouncing scenarios in a flat Friedmann–Limaître–Robertson–Walker spacetime within this framework. We explore bouncing scenarios with two different Lagrangian forms of f(Q) such as a linear and nonlinear dependence on Q. We have successfully examined all the energy conditions and stability analysis for both models to present a matter bounce.
