Forces: Balanced and Unbalanced

What is the net force in a balanced force situation?

• Net force = 0

• Net force > 0

• Net force < 0

• Net force is unknown

In a balanced force situation, what type of motion can be observed?

• No motion

• Constant motion

• Both A and B

• Change in motion

What is the net force in an unbalanced force situation?

• Net force = 0

• Net force ≠ 0

• Net force < 0

• Net force is unknown

In an unbalanced force situation, what can happen to an object?

• Speed up

• Slow down

• Change direction

• All of the above

In a balanced force, the net force is _____

• 0

• greater than 0

• less than 0

• equal to mass

What is the definition of net force?

• The difference between two forces

• The sum of all forces acting on an object

• The force of gravity only

• The force that moves objects upward

Look at the diagram with a box and two arrows labeled 5 N and 15 N pointing in the same direction. What is the net force acting on the object?

• 20 N

• 10 N

• 5 N

• 15 N

When two forces act in the same direction, you should:

• Subtract the forces

• Ignore one force

• Add the forces

• Multiply the forces

When two forces act in opposite directions, you should:

• Add the forces

• Subtract the forces

• Multiply the forces

• Ignore both forces

What does the segment labeled 'Toward Origin' represent on the graph?

• The object is moving away from the origin

• The object is not moving

• The object is moving toward the origin

• The object is moving at a fast speed
