Free Fall

Front

What is free fall?

Back

Free fall is the motion of an object under the influence of gravitational force only, without any air resistance.

Front

What is the acceleration of an object in free fall near the Earth's surface?

Back

The acceleration of an object in free fall near the Earth's surface is approximately 9.81 m/s² downward.

Front

How does the acceleration of a free-falling object change as it falls?

Back

The acceleration remains constant at 9.81 m/s² downward, regardless of the object's velocity.

Front

What happens to the velocity of a free-falling object as it falls?

Back

The velocity of a free-falling object increases as it falls, due to the constant acceleration of gravity.

Front

What is the direction of the acceleration of a free-falling object?

Back

The direction of the acceleration of a free-falling object is downward.

Front

If a ball is thrown upward, what happens to its velocity as it rises?

Back

The velocity of the ball decreases as it rises until it reaches its peak.

Front

What happens to the velocity of a ball after it reaches its peak height?

Back

After reaching its peak height, the velocity of the ball becomes negative as it falls back down.

Front

What is the relationship between velocity and acceleration in free fall?

Back

In free fall, velocity increases while acceleration remains constant.

Front

What is terminal velocity?

Back

Terminal velocity is 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 fall?

Back

Air resistance opposes the motion of a falling object, reducing its acceleration and eventually leading to terminal velocity.
