Students are playing tug-of-war. If group B pulls the rope to the right with a force of 400 N and group A pulls the rope to the left 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.

• 7 N Right

• 119

What is the net force (calculation).

• 5 N Right

• 19 N Left

• 13 N Right

• 13 N Left

Forces that have a net force of zero ( the object is still) are ?

• Unbalanced

• Balanced

What is a force?

• the PUSH or PULL on an object 
• The MOTION an object creates
• The objects HITTING one another
• Going REALLY FAST

If there are two forces going in the SAME direction, you would ...?

• (-) Subtract the forces
• (+) Add the forces
• Neither
• (x) Multiply

The correct equation to calculate speed is

• distance/time
• time/distance
• distance x time
• distance/time²
