What is balancing forces?

• Forces that act on an object but do not cause any motion

• Equal and opposite forces that act on an object

• Forces that cause an object to accelerate

• Forces that cause an object to move in a straight line

Give an example of balancing forces.

• Pushing a box with unbalanced forces

• Pushing a box with equal and opposite forces

• Pushing a box with no forces

• Pulling a box with equal and opposite forces

What happens to an object when the forces acting on it are balanced?

• The object remains at rest or continues to move at a constant velocity.

• The object changes direction randomly.

• The object comes to a stop.

• The object accelerates in the direction of the net force.

What happens to an object when the forces acting on it are unbalanced?

• The object will experience acceleration in the direction of the net force.

• The object will remain at rest.

• The object will experience deceleration in the direction of the net force.

• The object will experience a force in the opposite direction of the net force.

What is the net force when the forces acting on an object are balanced?

• zero

• unknown

• negative

• positive

What is the net force when the forces acting on an object are unbalanced?

• Vector sum of all the individual forces

• Resultant force

• Average force

• Opposing force

What is the unit of force?

• Kilogram

• Meter

• Newton

• Second

What are the two types of forces?

What is the difference between balanced and unbalanced forces?

• Balanced forces are not equal in magnitude and opposite in direction, while unbalanced forces are equal in magnitude and opposite in direction.

• Balanced forces are equal in magnitude and direction, while unbalanced forces are not equal in magnitude and/or direction.

• Balanced forces are equal in magnitude and opposite in direction, while unbalanced forces are equal in magnitude and opposite in direction.

• Balanced forces are equal in magnitude and opposite in direction, while unbalanced forces are not equal in magnitude and/or opposite in direction.

How can you change the motion of an object using forces?

• By applying a force

• By applying a force in the opposite direction

• By applying a force in the same direction

• By not applying any force
