Linear Kinematics Flashcards
Kinematic Equations
Vf=Vi+at
d=Vit+ 1/2at^2
Vf^2=Vi^2+2ad
Instantaneous Velocity
How how fast in what direction at a specific point in time (same as instantaneous speed)
Slope
Rise/Run (tangent of the lower angle of a triangle)
Horizontal Acceleration (projectile motion)
zero
Vertical Acceleration
acceleration due to gravity -9.8m/s^2
Which factors influence Projectile motion, which is most important
velocity of release (most important): increase Vh (distance and Vv time of flight
angle of release: increases time of flight only
relative height of release: affects ratio of vh and vv minimally
Horizontal Component of Velocity equation
Dh=Vh*Ttot
Optimal angle of release
always 45 degrees for even surface
less than 45 if takeoff is higher than landing
