What is the difference between balanced and unbalanced forces and their effect on an object?
Balanced forces cause an object to start moving, while unbalanced forces keep it at rest.
Balanced forces keep an object at rest at rest or moving at a constant velocity, while unbalanced forces cause a change in the object's motion.
There is no difference; both balanced and unbalanced forces have the same effect on an object.
Unbalanced forces cause an object to remain stationary, while balanced forces cause it to accelerate.
The correct answer is: Balanced forces keep an object at rest or moving at a constant velocity, while unbalanced forces cause a change in the object's motion.

How can a hockey stick cause the motion of a puck to change?
The hockey stick can apply a gravitational force, causing the puck to move downwards.
The hockey stick can apply an unbalanced force, causing the puck to accelerate in the direction of the force.
The hockey stick can apply a balanced force, keeping the puck stationary.
The hockey stick can apply a magnetic force, attracting the puck without touching it.
The correct answer is: The hockey stick can apply an unbalanced force, causing the puck to accelerate in the direction of the force.
How might you help your team members understand that only unbalanced forces can cause the motion of an object to change?
By showing them a game of tug-of-war where one team is pulling harder than the other
By discussing how a climber's path up a mountain is an example of balanced forces
By demonstrating a car moving at a constant velocity around a roundabout
