Kinematics in 1 Dimension Flashcards
Average Velocity
Acceleration
Kinematic Equation
(no position)
Kinematic Equation
(no final velocity)
Kinematic Equation
(no time)
Free Fall Equations
(Kinematic equations in the vertical direction)
Simple Ideas of Freefall motion
Only acceleration is gravity.
Vertical velocity is zero at the apex
Vertical velocity vs. time graph is a parabola.
Kinematic equations of motion should be written in the vertical direction with up as positive.
How is velocity shown on a position vs. time graph?
Velocity is the slope of the graph.
How is acceleration shown on a velocity vs. time graph?
Acceleration is the slope of the graph.
How is displacement shown on a velocity vs. time graph?
Displacement is the area under the curve.
How is velocity shown on an acceleration vs. time graph?
Velocity change is the area under the curve.
When does speed increase?
Velocity and acceleration have the same sign.
When does speed decrease?
When velocity and speed have opposite signs.
