What is the acceleration due to gravity on Earth (approximate value)?
g=9.8
True or False: The mass of an object affects the rate at which it falls in free fall.
False
A ball is dropped from rest. After 2 seconds, what is its velocity?
20 m/s
If an object is dropped from a height of 20 m, will its acceleration change as it falls? Why or why not?
No
What is the velocity of an object just before hitting the ground after falling freely for 3 seconds? Take g=10 m/s^2
30 m/s
A stone takes 4 seconds to reach the ground when dropped. What was the approximate height? Take g=10 m/s^2
80m
Give a real-life example where free fall occurs (ignoring air resistance).
True or False: An object in free fall has constant velocity.
False
If you drop a rock and throw another rock downward at the same time, which one has greater acceleration (ignoring air resistance)?
Same acceleration – both experience g
How far does an object fall in 10 seconds?
500 m
An object is dropped and falls for 6 seconds. Is its acceleration greater in the first second or the last second?
Same acceleration ( 9.8 m/s ^2 ) throughout the fall.
True or False: The acceleration due to gravity depends on the shape of the object.
False – acceleration due to gravity is the same for all objects (ignoring air).
