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…
