Projectile and Angular Motion Test
UPDATED Exam Questions and CORRECT
Answers
Object that moves through space acted on only by gravity (and air resistance if applicable) -
CORRECT ANSWER - Projectile
Near the surface of the earth, the path of a projectile is... - CORRECT ANSWER - Curved
parabolically
Horizontal and vertical components are... - CORRECT ANSWER - Separate
Velocity is always... - CORRECT ANSWER - Constant
The Vertical Component is also known as... - CORRECT ANSWER - Acceleration
Acceleration (or the Vertical Component) is always... - CORRECT ANSWER - Constant
Projectile motion is a combination of these two components - CORRECT ANSWER -
Vertical and Horizontal
When air drag is negligible, does the horizontal component of a horizontally launched projectile
change? - CORRECT ANSWER - No because the object would travel the same horizontal
distance in equal times (no component of gravitational force acting horizontally) and remains
constant.
When air drag is negligible, does the vertical component of a horizontally launched projectile
change? - CORRECT ANSWER - Yes
, With time, vertical positions become... - CORRECT ANSWER - Farther apart
Why does a horizontally launched object always accelerate downward? - CORRECT
ANSWER - Because the force of gravity always acts downward
This is the combination of horizontal and vertical components of motion. - CORRECT
ANSWER - Curvature of Path
When a projectile is fired horizontal from a height, the object moves forward at this kind of
speed - CORRECT ANSWER - Constant
What shape does the path of a projectile that undergoes acceleration only in the vertical
direction, while moving horizontally at a constant speed make? - CORRECT ANSWER -
Parabola
When a projectile is fired horizontally, the vertical component at any point can be found using
this equation - CORRECT ANSWER - The Pythagorean Theorem (diagonal of a rectangle)
Without air resistance, the time for a projectile to reach maximum height is _______ as the time
for it to return to its initial level. - CORRECT ANSWER - the same
The line around or about which rotation or revolution takes place - CORRECT ANSWER -
Axis
Also called spin, this is what an object does when turning around an internal axis - CORRECT
ANSWER - Rotation
This is what an object does when turning around an external axis - CORRECT ANSWER -
Revolution
