Projective Motion Flashcards
A projective is
Any object moving though the air unassisted (free falling, self-propulsion, ect.)
A trajectory is
The flight path of a projective
What are the three general shapes of a trajectory
l. Vertical trajectory (directly up and down)
2. Oblique trajectory (curved)
3. Horizontal trajectory (higher to lower : in a stright-ish line)
Projectile motion is a form of what type of motion
Linear
Range is
The distance covered by a projectile
Projectile motion often falls under the sub category of
Curvilinear motion
Do horizontal and vertical components of a trajectory affect each other
No they are independent
The vertical component of a projectile is primary affect by
Gravity
What determines the flight time of a projectile
The vertical component
What determines the range (distance traveled) of a projectile
The horizontal component
Apex is
The highest point of the trajectory
At the apex of a projectile what is vertical component at
Zero
At the apex of a projectile what is vertical component at
Zero
VY means
Vertical component
VX means
Horizontal component
The horizontal distance with no concern for direction is called
The range
Projection speed is
The speed at which the projectile is moving at the point of release
Projection is an average or instantaneous quantity
Instantaneous
Projection angle is
The angle at witch a projectile is thrown at
Projection speed and projection angle both play a role on height and/or range but what one is more important
Projection angle
What is the optimal angle for a human
45 degrees
What are 3 factors to achieve greatest range in a projectile
l. Projection angle
2. Projection speed
3. Relative height of projection
Relative projection height is
The difference between the point of realease and the landing point
In projective motion acceleration is
Constant
