• 8 N to the right

• 2 N to the right

• 2 N to the left

• 0 N (balanced force)

A box is being pushed with 6 N to the right while friction applies 6 N to the left. What is true about the forces?

• They are balanced, and the box stays at rest or moves at a constant speed.

• They are unbalanced, so the box will accelerate.

• The box will move to the right.

• The forces cancel out, but the box will still accelerate.

A cart is moving at a constant speed. What can be concluded about the forces acting on it?

• They are balanced, so the cart moves at a constant speed.

• They are unbalanced, causing the cart to speed up.

• The cart is accelerating in different directions.

• No forces are acting on the cart.

Two students are pushing a heavy box from opposite sides. One pushes with 50 N to the right, and the other pushes with 40 N to the left. What will happen to the box?

• It will move to the right with 10 N of force.

• It will move to the left with 10 N of force.

• It will not move because the forces cancel out.

• It will move in both directions at the same time.

A moving cart has an unbalanced force applied to it. What will happen next?

• It will continue moving at the same speed.

• It will slow down, speed up, or change direction.

• It will stop immediately.

• It will move backward.

A tug-of-war game is tied at first, but then one team starts pulling harder. What is happening in terms of forces?

• The forces are balanced, so neither team moves.

• The forces become unbalanced, so the stronger team wins.

• The forces stay equal, so both teams move toward each other.

• Gravity suddenly changes the forces.
