Friction, I think
Friction .
During a fee fall, when there is no normal force to resist the force of gravity, the body's acceleration is the same as the force of gravity 9.8m/s-2
Friction or drag
While this sounds like a question that is specific to a certain situation, it sounds like you're talking about air resistance. It always opposes motion and (for small objects) is modeled as being proportional to the magnitude of velocity.
Lift is the upward force that opposes the force of gravity.
Friction.Called inertia. To accelerate a body the force is mass times acceleration. No force = no acceleration. People say " the force is opposed by the massacceleration"

Friction .
The force of gravity opposes acceleration away from the source of the gravity. This is expressed as "centrifugal force" or the perpendicular component of a tangential velocity. The balance between these keeps the planets in orbit around the Sun.

Lift is the upward force that opposes the force of gravity.
No change in motion (speed or direction) means no acceleration.No acceleration means zero net force.
Centripetal acceleration is acceleration towards the center of the movement.
When you apply a force there is always an equal and opposite force applied to resist change as newtons first and third law state. The force the object applies to resist change is the resistance force. An example is the force supplied by the sidewalk when you walk on it.
Gravity. The inertia of an object will keep it moving until an opposing force stops it.Friction.Called inertia. To accelerate a body the force is mass times acceleration. No force = no acceleration. People say " the force is opposed by the massacceleration"
