Question
Megan left her wagon outside while it was raining and it filled with water. When Megan tried to move the wagon that afternoon, she failed to budge the wagon. Why did Megan's wagon become hard to move?
Responses
The rainwater decreased the force of gravity pushing on the wagon, increasing the force needed to move it.

ARE YOU SURE
Yes, I am sure. When the wagon fills with water, the additional mass of the water increases the overall mass of the wagon. According to Newton's second law of motion, F = ma, where F represents force, m represents mass, and a represents acceleration. As the mass of the wagon increases, more force is required to accelerate or move the wagon. Therefore, the rainwater increases the mass of the wagon, increasing the amount of force needed to move it.
