Vectors and Projectiles Flashcards
Examples of scalar quantites
mass, volume, speed, distance
examples of vector quantites
force, velocity, acceleration, displacement
vectors represented by
putting an arrow above the letter symbol
the length of the arrow represents
the direction of the arrow represents
the magnitude
the direction on the vector
the sum of two vectors is called
a resultant
vectors are added
head to tail
what are the 2 components of a single vector can be broken down into
a horizontal and vertical compnent
a projectile is
any object that is projected by some means and continues in motion by its own inertia
a projectile can be broken down into
a horizontal and vertical component
Horizontal component (4) (projectiles)
- if no friction, velocity is constant
- object moves an equal distance each s
- no acceleration
- d=v(average)t
Vertical component (5) (projectiles)
- force of gravity acts upon it
- if no air resistance, free fall
- acceleration is uniform and is g
- velocity is constantly increasing
- d=1/2 gt^2
Projectiles launched horizontally (if neglecting F air and friction) will experience
gravity (vertical)
Projectiles launched at an angle
with no gravity would follow
a straight line
Projectiles launched at an angle with gravity
falls beneath this straight line with the same vertical distance as if it fell from rest
Projectiles:
horizontal velocity is
the same everywhere
