Question

which type of force is she demonstrating in this position?
static friction
rolling friction
sliding friction
fluid friction

Explanation:

Static friction acts on objects when they are at rest relative to a surface. In the image, the person is stationary and in contact with the surface, so the force demonstrated is static friction. Rolling friction occurs with rolling - objects, sliding friction with moving - across surfaces in contact, and fluid friction in fluids.

Answer:

static friction
