Unit B Flashcards
Displacement
when an object moves from one position to its final position, the change in the positions
shortest distance between the two positions
distance
total movement from its initial to final position
average speed
total distance over time
average velocity
displacement over time
is velocity constant when direction changes?
no
For kinematics, what is required for acceleration?
constant acceleraton
acceleration
final velocity - initial velocity over time
What is assumed of x and t when using kinematic equations?
That initial position and time is 0 so the final value is the total amount
when an object is going down, what is the value of the height, velocity
it is negative
what is the value of velocity at max height
0
In projectile motion, when ax=0 what is the value of velocity?
Since acceleration is 0 in the x direction that means velocity in the x direction is constant and will be the same value. Vo and Vf will be the same number.
At half of the projection what happens to the velocity and time?
It’s half the time and vy=0
