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 happens to the velocity of an object in free fall?

Back

The velocity of an object in free fall increases as it falls due to the acceleration of gravity.

Front

What is the acceleration due to gravity on Earth?

Back

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

Front

What is the direction of the velocity of an object thrown upward?

Back

The direction of the velocity of an object thrown upward is upward.

Front

What happens to the velocity of an object as it rises in the air?

Back

The velocity of an object decreases as it rises in the air due to the force of gravity acting downward.

Front

What is the direction of the acceleration of an object in free fall?

Back

The direction of the acceleration of an object in free fall is downward, towards the center of the Earth.

Front

What happens to the acceleration of an object in free fall?

Back

The acceleration of an object in free fall remains constant at approximately 9.81 m/s².

Front

What is terminal velocity?

Back

Terminal velocity is the constant speed an object reaches when the force of gravity is balanced by the drag force of the air.

Front

How does air resistance affect free fall?

Back

Air resistance opposes the motion of falling objects, reducing their acceleration and eventually leading to terminal velocity.

Front

What is the difference between velocity and speed?

Back

Velocity is a vector quantity that includes direction, while speed is a scalar quantity that only measures how fast an object is moving.
