An example of such a force is friction, but a term for forces that act against motion are decelerative forces.
Newton's Third Law states that for every action, there is an equal and opposite reaction. However, these can be in any direction and may or may not influence an object in motion.
The opposite of motion is motion in the opposite direction e.g. if you push an object to the left the opposite would be pushing force applied to the right
opposing the motion
Friction always acts opposite to the direction of motion.
Friction acts in the opposite direction of the object's motion
The direction of the force of friction is opposite of the direction of the motion.
Because the force generated is always opposite the direction of motion.
Friction
opposing the motion
A force that resists motion between two touching surfaces and always acts opposite to the direction of motion is called friction. Friction will slow down a car when the brakes are applied.
it acts in the opposite direction of motion or force
Friction always acts opposite to the direction of motion.
Friction always acts opposite to the direction of motion.
