The Path of a projectile with constant horizontal motion and a downward acceleration due to gravity is a(n)
Parabola
Circle the letter of the vertical component of velocity for the projectile at the peak of its trajectory.
Zero
When an object is projected horizontally, what is its initial vertical velocity?
0
This is because...
When its projected horizontally, it has no vertical velocity
An object is projected horizontally from a cliff. The time it takes to hit the ground is.
The same amount of time as if it was dropped
This is because...
Horizontally projected objects have the same vertical velocity as dropped objects
As an object travels through the air, its vertical velocity
changes continuously
This is due to the fact that
A net force is acting in the object vertically (due to gravity)
As an object is traveling through the air, its horizontal velocity
remains the same
This is because...
No net force acts on the object horizontally
An arrow is shot from a bow horizontally at a speed of 150 mph. At the same time a second arrow is dropped (from the same height as they shot the arrow) which hits
they hit at the same time
This is due to the fact that
both accelerates downwards 10m/s2, regardless to their horizontal velocity
