Approximately how far can an object fall in 5 seconds?
A free falling objects falls under the influence of the
force of air
force of gravity
force of resistance
If you throw a baseball straight up, what is its vertical (y-direction) velocity at the highest point?
A ball is thrown upward in the air with an initial velocity of 40 m/s. How long does it take to reach its highest point in the air?
A freely falling object starts from rest. After falling for 6 seconds, it will have a speed of about:
Which would hit the ground first if dropped from the same height in a vacuum—a feather or a metal ball?
the metal ball
They would hit the ground at the same time.
They would not fall at all in a vacuum.
What is acceleration of an object flying upward during free fall?
+ 9.8 m/s2
- 9.8 m/s2
+ 9.8 m/s
In a normal environment, like the classroom, why does a bowling ball and feather hit the ground at different times when dropped from the same height?
They don't; they hit the ground at the same time.
One is more dense than the other.
One is heavier than the other.
Heavier objects free fall faster than lighter objects.
