A freely-falling watermelon falls with constant

• velocity
• speed
• acceleration
• distances each successive second.

While an iron block near the Earth's surface is in free fall, it undergoes an increase in

• speed.
• acceleration
• both of these
• neither of these

The distance a freely falling bowling ball falls each second 

• is about 5 m
• is about 10 m.
• increases
• none of the above

Twelve seconds after starting from rest, a freely-falling cantelope has a speed of

• 10 m/s
• 50 m/s
• 100 m/s
• more than 100 m/s

An apple falls from a tree and hits the ground 5 meters below with a speed of about

• 5 m/s.
• 10 m/s.
• 15 m/s.
• 20 m/s.

If a stone falls to the bottom of a mineshaft in 6 seconds, then the depth of the shaft is about

• 60 m
• 120 m
• 180 m
• more than 200 m

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

• 5 m/s
• 10 m/s
• 15 m/s
• a variable amount

If a freely falling object were equipped with a speedometer on a planet where the acceleration due to gravity is 20 m/s2, then its speed reading would increase each second by

• 10 m/s
• 20 m/s
• 30 m/s
• 40 m/s

If an object falling freely were somehow equipped with an odometer to measure the distance it travels, then the amount of distance it travels each succeeding second would be

• constant
• less and less each second
• greater than the second before
• doubled

An object at rest near the surface of a distant planet starts to fall freely. If the acceleration there is twice that of the Earth, its speed one second later would be

• 10 m/s
• 20 m/s
• 30 m/s
• 40 m/s
