Fall Final Exam

Front

What is the acceleration due to gravity for free-falling objects on Earth?

Back

9.8 m/s²

Front

What is the velocity of a baseball at the highest point when thrown straight up?

Back

0 m/s

Front

How long does it take for an object to fall from a height of 30 m under the influence of gravity?

Back

3.0 seconds

Front

If a freely falling object is equipped with a speedometer, how much does its speed increase each second?

Back

About 10 m/s

Front

In a vacuum, which object accelerates faster: a leaf or a stone?

Back

They would accelerate at the same rate.

Front

What is Newton's 2nd Law of Motion?

Back

The acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass (F = ma).

Front

What is the formula to calculate the distance fallen by an object in free fall?

Back

d = 0.5 * g * t², where g = 9.8 m/s² and t is time in seconds.

Front

What is the significance of air resistance in free fall?

Back

Air resistance opposes the motion of falling objects, affecting their acceleration and terminal velocity.

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 mass affect the acceleration of an object in free fall?

Back

In a vacuum, mass does not affect the acceleration; all objects fall at the same rate regardless of mass.
