Post FD Flashcard Review

Front

What is the net force acting on an object that is slowing down due to friction?

Back

The net force is negative, indicating that it is acting in the opposite direction of the object's motion.

Front

What force acts on an object in free fall?

Back

The only force acting on an object in free fall is the gravitational force exerted by the Earth.

Front

What does it mean for an object to be in equilibrium?

Back

An object is in equilibrium when the net force acting on it is zero, resulting in no acceleration.

Front

What directions are considered positive in this class?

Back

Right and Up are considered positive directions.

Front

What is terminal velocity?

Back

Terminal velocity is the constant speed reached by an object when the force of air resistance is equal to the force of gravity acting on it.

Front

What is friction?

Back

Friction is a force that opposes the motion of an object, acting parallel to the surface of contact.

Front

What happens to the net force when an object is at rest?

Back

The net force is zero when an object is at rest, meaning all forces acting on it are balanced.

Front

What is the role of air resistance in falling objects?

Back

Air resistance opposes the motion of falling objects and can lead to terminal velocity.

Front

How does the direction of force affect motion?

Back

The direction of force determines the direction of acceleration and thus the motion of the object.

Front

What is the difference between balanced and unbalanced forces?

Back

Balanced forces result in no change in motion, while unbalanced forces cause an object to accelerate.
