Free Fall

Front

Distance a ball falls after 1,2,3,4,5 seconds (assume g is rounded to 10 m/s²)?

Back

5, 20, 45, 80,125 m (meters)

Front

What is the velocity of a ball that has been dropped off a cliff after 1, 2, 3, 4, and 5 seconds? (assume g is rounded to 10 m/s²)?

Back

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

Front

What is the acceleration of a ball that is dropped off the side of a cliff after 1,2,3,4,5 seconds? (assume g is rounded to 10 m/s²)

Back

10,10,10,10,10 m/s²

Front

A ball is thrown upward in the air with an initial velocity of 40 m/s. How long does it take to reach back to the point it was thrown from?

Back

8 seconds

Front

A ball is thrown up in the air with an initial velocity of 40 m/s. What is the ball's velocity after 2 seconds?

Back

20 m/s traveling upward

Front

A ball is thrown up in the air with an initial velocity of 40 m/s. What is the ball's velocity after 6 seconds?

Back

20 m/s traveling downward.

Front

Can you find the Vf of an object if you know the time it is in the air?

Back

Yes, you would have to halve the time since the Ttotal is for both rise and fall and you would have to calculate the height the object rose before finding the Vf.

Front

The change in velocity in a given time period is?

Back

a

Front

Which would fall with greater acceleration in a vacuum—a leaf or a stone?

Back

They would accelerate at the same rate.

Front

If a freely falling object were somehow equipped with a speedometer, its speed reading would increase each second by

Back

about 10 m/s.
