Scalar v. vector
Displacement v. distance, speed v. velocity
How to calculate displacement
The SLOPE of distance v. time is velocity/speed
The SLOPE of vecloity/speed v. time is acceleration
distance = rate * time
Vertical velocity changes, horizontal doesnt
Change in velocity/change in time = acceleration
As I increase the angle at which i launch something, the vertical component of the velocity goes up, the horizontal component goes down.
Centripetal acceleration increases with increased velocity, and decreases with increased radius, and always points IN
Remember/memorize the BIG FIVE equations!
