Semester 1 Force Review

With unbalanced forces, the object will move in the direction of the _______ force.

• larger 
• smaller 
• equal 

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

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

If there are two forces going in opposite directions how would you find the net force?

• Subtract

• Add

• Neither

• Multiply

What is the net force?

• 5.5 N left
• 5.5 N right
• 2.5 N left
• 2.5 N right

What is the net force?

• 65 N left
• 65 N right
• 35 N left
• 35 N right

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

• Balanced force
• Unbalanced force

How will this object move?

• It won't move.

• It will accelerate to the right.

• It will accelerate to the left.

• It will accelerate in both directions.

The sum of all forces acting on an object and direction

• Contact Force
• Balanced Force
• Unbalanced Force
• Net Force

What is Newton's Third Law of Motion?

• an object at rest stays at rest, and an object in motion will stay in motion until an outside force acts upon it

• the acceleration of an object will be equal to the net force of an object divided by its mass

• for every action, there will be an equal and opposite reaction

• an object that is not moving will stay not moving moving until an unbalanced force acts on it

What will cause an object to move?

• Applied forces
• Balanced forces
• Unbalanced forces
