Friction, when moving sideways.
Upthrust when you are trying to go down.
gravity when you are trying to go up
Friction and Gravity are the main causes why objects slow down.
Friction and Air Resistance
The force that slows down moving objects is friction, the action of two objects rubbing against each other. This scenario illustrates the action of Newton's Second Law.
Whenever any object moves through air (eg an aeroplane) it observes four forces 1 Drag force 2. lift force 3.weight of object 4.thrust created by the propellers or engine of the object. The drag force is directed opposite to the direction of moment of the object and slows the object down.
friction slows it down
The vertical components of the air resistance acts vertically down on it. This adds to the effect of the gravitational force. Therefore net force is increased - it slows down more rapidly and so does not rise as far.
friction stops things from moving and slows it down

Friction and Air Resistance
The limiting frictional force is the force that slows down the tennis ball on the roller coaster.
friction
Whenever another force - usually friction - slows it down.
Friction
Static electricity has electricity and friction makes heat and slows things down.
friction is the force that slows things down or prevent things from moving
