|
change of an object's position in time / displacement over time
|
motion
|
|
|
the change in an object's position and is measured in units of length
|
displacement
|
|
|
1. has magnitude and direction
2. Examples are displacement, velocity, acceleration |
vector quantity
|
|
|
Kinematic equation when you don't have velocity final
|
displacement = (initial velocity)(time) - (1/2)(acceleration)(time-squared)
|
|
|
Kinematic equation when you don't have displacement
|
(final velocity) = (initial velocity) + (acceleration)(time)
|
|
|
Kinematic equation when you don't have time
|
(final velocity)squared = (initial velocity)squared + 2(acceleration)(displacement)
|
|
|
Kinematic equation when you don't have acceleration
|
displacement = (1/2)(time)(initial velocity - final velocity)
|
|
|

|
zero
|
|
|
In projectile motion, the acceleration in the x-direction is always
|
zero
|
|
|
In projectile motion, the acceleration in the y-direction is always
