requires magnitude and direction (velocity and acceleration)
requires magnitude only (mass/speed)
pictorial presentation of a vector quantity
length of arrow
direction of arrow
helps you (assume perpendicular)
4 sides opposite angles are parallel and congruent
2 components are at right angles with the same magnituedes
use √2 rule
any object that moves through the air or through space, acted on only by gravity
responsible for hang time (gravity
only responsible for range (air resistance
horizontal and vertical
are independent of each other
falling at same rate both affected by gravity
shows magnitude and direction of projectile
vector sum of two or more component vectors
the process of resolving a vector into components
at peak v is 0 and h becomes resultant and never goes slower that that
same speed at every attempt , different ranges
minimum speed km/s, 8000
8 km/s, 8000 m/s, 18000 mi/h (burn up)
with satellite have to go
over 150km above earth or it will burn up
t=d/sp (range or t=√2d/g(vertical)
