Why is it more difficult for Person B to move down the hill than Person A?
There's more friction between the ground and Person B than there is for person A.
There's less friction between the ground and Person B than there is for person A.
There's the same amount of friction between the ground for both Person A and B.
Person B is experiencing higher levels of air resistance than Person A.
What are balanced forces?
Forces in the same direction
Forces of identical magnitude (size)
Forces of the same size in opposite directions
Forces of different sizes in the same direction

Students are playing tug-of-war. If group B pulls the rope with a force of 400 N and group A pulls the rope with a force of 250 N, what will happen to the ribbon in the middle of the rope?
The ribbon will move to the left and group A will win the tug-of-war.
The ribbon will move to the left and group B will win the tug-of-war.
The ribbon will move to the right and group B will win the tug-of-war.
The ribbon will move to the right and group A will win the tug-of-war.
A cyclist traveling at 25 km/h turns sharply to the left without changing her speed. The forces in this situation are -
Balanced, because the cyclist's speed did not change.
Balanced, because she is still moving forward.
Unbalanced, because the cyclist's speed remains constant.
Unbalanced, because her direction changed.
