Free Fall Conceptual Questions

Front

Do free falling objects move at constant velocity or do they accelerate?

Back

Falling objects accelerate at -10 m/s².

Front

________________ is any motion of a body where gravity is the only force acting upon it.

Back

free fall

Front

What happens to the velocity of a ball as it is dropped off a cliff?

Back

It increases at a uniform rate.

Front

A textbook is dropped from a second floor window and falls to the ground. What happens to the velocity as the book falls to the ground?

Back

the velocity increases.

Front

A ball is projected upward with an initial speed of approximately 40 m/s. At what location will the ball be moving downward with a speed of approximately 20 m/s?

Back

G

Front

What is the acceleration due to gravity near the Earth's surface?

Back

Approximately -9.81 m/s².

Front

What is the difference between free fall and projectile motion?

Back

Free fall is motion under gravity alone, while projectile motion involves an initial velocity and follows a curved path.

Front

What is terminal velocity?

Back

The constant speed that a freely falling object eventually reaches when the resistance of the medium prevents further acceleration.

Front

How does air resistance affect free falling objects?

Back

Air resistance opposes the motion, reducing acceleration and eventually leading to terminal velocity.

Front

What is the formula for calculating the distance fallen in free fall?

Back

d = 0.5 * g * t², where g is the acceleration due to gravity and t is time.
