What is the definition of balanced forces?
Forces that are unequal in size and opposite in direction
Forces that are equal in size and opposite in direction, resulting in no change in an object's motion.
Forces that are equal in size and same in direction
Forces that are unbalanced in size and direction
Give an example of unbalanced forces in action.
A person pushing a shopping cart with a constant force.
A car accelerating forward while the brakes are being applied.
A book resting on a table.
A car moving at a constant speed on a straight road.
How do balanced forces impact the overall movement of an object?
Balanced forces make the object move in a circular path.
Balanced forces do not change the object's state of motion.
Balanced forces cause the object to accelerate indefinitely.
Balanced forces result in the object changing direction constantly.
Which of the following indicate unbalanced forces acting on an object?
When the net force is zero.
When the object is moving at a constant speed.
When the object is at rest.
When the net force acting on the object is not zero.
What happens to an object when the forces acting on it are balanced?
The object accelerates
The object disappears
The object changes color
The object remains at rest or continues moving at a constant velocity.
Can unbalanced forces ever result in an object remaining at rest?
Yes
No

What is the definition of unbalanced forces?
Forces that are equal in size and opposite in direction
Forces that are not equal in size and same in direction
Forces that are not equal in size and opposite in direction
Forces that are not equal in size and random in direction
How do balanced forces affect an object?
They cause the object to slow down
They cause the object to change direction
They cause the object to speed up
They do not cause any change in the object's motion.
