• the sum of the two forces
• Only one of the forces acts on the object
• DOOMSDAY!

How could you make an object increase its speed?

• use less force
• use more force
• use no force

What is the net force?

• 400 N Up

Why does a book on a table not move?

• No forces are acting on the book
• Gravity is the only force acting on the book
• Forces of the table pushing up and gravity pulling down are balanced

What will cause an object to move?

• Applied forces
• Balanced forces
• Unbalanced forces

(T or F?) A balanced force is only an object that is not moving. 

• True 
• False
