A force is simply a push or a pull.

Gravity or weight is always acting downwards

Reaction force from a surface, usually acting straight upwards

Electrostatic force between two charged objects. The direction depends on the type of charge (like charges repel, opposite charges attract)

Thrust or push or pull due to an engine or rocket speeding something up

Drag or air resistance or friction which is slowing the thing down

Lift due to an airplane wing

Tension in a rope or cable

The forces acting on you currently all balance themselves out

Any object with a weight feels a reaction force back from the surface its on. Otherwise it would just keep falling

When an object moves in a fluid (air, water) it feels drag in the opposite direction to its motion

Friction is always there to slow things…
