What happens to the velocity of a ball as it is dropped off a cliff? 

• It decreases at a uniform rate 

• It increases at a uniform rate 

• It is constant 

• It increases at a non-uniform rate

A pumpkin is dropped from a 35 m building. What is its initial velocity (v_i)?

• 9.8 m/s²

• 35 m

• 0 m/s

• 9.8 m/s

As the height of a vertical drop increases we would expect to see

• The diameter increase and fewer spines and satellites

• The diameter decrease and fewer spines and satellites

• The diameter increase and more spines and satellites

• The diameter decrease and more spines and satellites

Do free falling objects move at constant velocity or do they accelerate?

• Falling objects accelerate at -9.8 m/s²

• Falling object move at constant velocity

• Falling objects accelerate at 100 m/s²

• It depends on the mass: heavy objects accelerate, light objects do not

What values are always known for a free falling object?

• v_i = 0 m/s
   a = -9.8 m/s²

• v_i = -9.8 m/s
   a = -9.8 m/s²

• v_i = -9.8 m/s
   a = 0 m/s²

• d = -9.8 m
  v_i = 0 m/s

The standard acceleration due to gravity (or standard acceleration of free fall),is the nominal gravitational acceleration of an object in a vacuum near the surface of the Earth. It is defined by standard as:

• 9.8 m/s.

• 9.8 m.

• 9.8 m/s².

• 9.8 s.
