Free Fall

Front

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

Back

The direction of acceleration for an object in free fall is downward.

Front

When a baseball is thrown upward, what is the direction of its acceleration?

Back

The direction of acceleration is downward.

Front

What happens to the velocity of a baseball thrown upward as it rises?

Back

The velocity of the baseball is upward as it rises.

Front

If a ball is thrown upward with an initial speed of 30 m/s, what is the speed of the ball when it is at its highest point?

Back

The speed of the ball at its highest point is 0 m/s.

Front

What is the acceleration of a baseball thrown upward as it rises?

Back

The acceleration remains constant at approximately -9.81 m/s² (downward) regardless of the ball's position.

Front

What is the effect of air resistance on a falling object?

Back

Air resistance opposes the motion of a falling object, reducing its acceleration.

Front

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

Back

The formula is d = 0.5 * g * t², where d is distance, g is acceleration due to gravity (approximately 9.81 m/s²), and t is time.

Front

What is terminal velocity?

Back

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

Front

How does the acceleration of an object in free fall change as it falls?

Back

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

Front

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

Back

In free fall, velocity increases downward while acceleration remains constant.
