A Soccer Player Sliding on a Wet Field: Explaining Newton's First Law
Why Does the Soccer Player Eventually Come to a Stop?
Answer: The answer is D. An object in motion will stay in motion unless acted upon by an outside force. Wet soccer field is not a smooth surface. When he slides across wet field, he is being acted upon frictional force which acts opposite to the direction of his motion. Due to this, all his kinetic energy is converted into heat and finally comes to rest.
a: the soccer player has no acceleration
b: the soccer player has inertia
c: the field is a frictionless surface
d: forces act on the soccer player The answer is D. An object in motion will stay in motion unless acted upon by an outside force. Wet soccer field is not a smooth surface.
