Resultant Vector

You and your dad are moving the couch from one side to another. Your dad pushes with a force of 35 N to the right and you push with a force of 25 N right. What is the net force on the couch?

• 60 N right

• 10 N left

• 50 N right

• 50 N left

If there are two forces going in the same direction how would you find the net force?

• Subtract
• Add
• Neither
• Multiply

What is a force?

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

What is the net force?

• 17 N Right
• 3 N Right
• 3 N Left
• 17 N Left

Name two quantities that are vectors.

• force and speed
• speed and acceleration
• force and acceleration
• mass and weight

Two forces on an object are in the same direction. How do we calculate the resultant force?

• take away one from the other
• multiply them
• divide one by the other
• add them together

Two forces on an object are in opposite directions. How do we calculate the resultant force?

• divide one by the other
• multiply them
• find the difference between them
• add them together
