Free Fall

Front

What is free fall?

Back

Free fall is the motion of an object under the influence of gravitational force only, with no other forces acting on it.

Front

What direction does the acceleration of a freely falling object point?

Back

The acceleration of a freely falling object always points downward, towards the center of the Earth.

Front

What happens to the velocity of an object in free fall as it descends?

Back

The velocity of an object in free fall increases as it descends.

Front

What is the value of acceleration due to gravity on Earth?

Back

The acceleration due to gravity on Earth is approximately 9.81 m/s².

Front

Does the acceleration of a freely falling object change as it falls?

Back

No, the acceleration remains constant at approximately 9.81 m/s².

Front

What is the relationship between velocity and time for an object in free fall?

Back

The velocity of an object in free fall increases linearly with time.

Front

If a ball is thrown upward, what happens to its velocity at the peak of its motion?

Back

At the peak of its motion, the velocity of the ball is zero before it starts to fall back down.

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.

Front

What is the difference between speed and velocity?

Back

Speed is a scalar quantity that refers to how fast an object is moving, while velocity is a vector quantity that includes both speed and direction.
