What type of force is friction in a force diagram?
A force that always acts upward.

How does air resistance affect the acceleration of a falling object?
It increases acceleration.

It does not affect acceleration.
It reverses acceleration.
What does a larger arrow in a force diagram indicate compared to a smaller arrow?
Less force
More force
The same amount of force
Direction of force only

What does it mean if the forces on an object are unbalanced?
The object is at rest.

What is the role of air resistance in the motion of a parachute?
It speeds up the descent.
It has no effect.
It slows down the descent.
It changes the direction of descent.
In a force diagram, what does an arrow pointing to the right typically indicate?
The object is moving to the left.
The object is moving to the right.
The object is accelerating to the right.
The object is experiencing a force to the right.
What happens when the gravitational force on an object is equal to the air resistance force?
The object accelerates.
The object decelerates.
The object moves at a constant velocity.
The object stops moving.
Which of the following is NOT a force shown in typical force diagrams?
