vocabulary
100
What is the slope on a velocity-time graph?
Vf-Vi/ △ t or acceleration
100
how to calculate the initial velocity?
Vi=Vf-aav*△t
100
What is the defination of acceleration.
Acceleration is defined as the rate of change of velocity
200
If a velocity-time graph shows a straight diagonal line going upwards, what can we assume it's acceleration-time graph will look like?
there will be a flat, horizontal line.
200
how to calculate the acceleration
aav=vf-vi/△t
200
what is negative acceleration?
the final velocity is less than the initial velocity.
300
Describe what the line of best fit will look like for positive, negative, and zero acceleration.
positive=moving upwards, negative=moving downwards, zero=horizontal line.
300
how to calculate the time.
△t=vf-vi/aav
300
what is instantaneous acceleration?
the acceleration of an object at a particular instant in time.
400
Calculate. Vf=+40m/s,Vi=+15m/s, △t=10s.
+2.5m/s2
400
how to calculate the final velocity?
Vf=vi+aav*△t
400
what is zero acceleration?
the acceleration that has constant velocity.
