FreeFall

Front

What is the acceleration of free-falling objects on Earth?

Back

-9.8 m/s²

Front

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

Back

0.0 m/s

Front

Calculate the velocity of a ball dropped from a height after 1, 2, 3, 4, and 5 seconds (assuming g = 10 m/s²).

Back

10, 20, 30, 40, 50 m/s

Front

What is true about the motion of a ball tossed upward?

Back

It has constant acceleration on the way up, at the top of its path, and as it moves downward.

Front

If you have a hang time of 2 seconds on Earth, how high did you jump?

Back

About 5 m.

Front

Define free fall.

Back

The motion of an object where gravity is the only force acting upon it.

Front

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

Back

d = 0.5 * g * t², where g is acceleration due to gravity and t is time.

Front

What does 'g' represent in free fall equations?

Back

The acceleration due to gravity, approximately 9.8 m/s² on Earth.

Front

Explain the concept of terminal velocity.

Back

The constant speed an object reaches when the force of gravity is balanced by the drag force of the medium through which it is falling.

Front

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

Back

The speed increases due to constant acceleration from gravity.
