Two football linemen push against each other in practice. They do not move, but then lineman B moves forward and lineman A moves backward.

Why does this happen?

Question 4 options:

Because the lineman push in different directions, the net force is zero.

When the lineman push on each other, they cause action-reaction forces that are unequal.

The forces are balanced, but then line B exerts a greater force, causing unbalanced forces.

Lineman A pushes with a greater force, causing a net force that acts in his direction.
