Air resistance and gravity.

When you drop a feather, the two main forces that will affect it are gravity, which pulls the feather downward towards the ground, and air resistance, which pushes against the feather as it falls, slowing its descent.
The two forces that affect acceleration are net force and mass. Acceleration is directly proportional to the net force acting on an object and inversely proportional to the mass of the object.
Two forces that affect us when we float in water are buoyancy, which pushes us upwards due to the displacement of water, and gravity, which pulls us downwards. The interaction between these two forces determines our stability and position while floating.
friction and gravity
Two forces that can affect an object's velocity are acceleration and friction. Acceleration can increase or decrease the velocity of an object, while friction can slow down the object's motion by opposing its direction of movement.
Two forces that affect nearly all motion are gravity, which pulls objects towards the Earth's center, and friction, which opposes the motion of objects moving against a surface.
