The dry sidewalk has more friction compared to the ice on the icy sidewalk
Friction
Friction is the force that makes it less likely for a person to slip on a dry sidewalk compared to an icy sidewalk. Dry surfaces provide more friction between the shoe and the ground, allowing for better grip and stability. Ice reduces this friction, making it easier for a person's foot to slip.
When a person pushes against the sidewalk, they exert a force in the opposite direction. According to Newton's third law of motion, for every action, there is an equal and opposite reaction. This means the sidewalk exerts an equal and opposite force on the person, propelling them forward.
The force of friction between the person's shoes and the sidewalk prevents their feet from slipping. Friction is generated by the contact between the irregularities on the shoe sole and the rough texture of the sidewalk surface, providing the necessary grip for walking.
Frictional force. On a rainy day, the property of the sidewalk changes the coefficient of friction, causing you more likely to fall.
Both, you exert a force onto the sidewalk, and the sidewalk "pushes back" with an equal, but opposite force.
The antagonist is the person or force that opposes the central character (protagonist) in a story. They create conflict and obstacles for the protagonist to overcome, driving the plot forward.

A force that opposes the direction of motion is called a resistive force or frictional force. It acts in the opposite direction to the motion of an object, reducing its speed or stopping it altogether.

Lift is the upward force that opposes the force of gravity.
