Physics Motion Test

Constant Velocity (forward)

Position time graph with initial forward motion, but slowing down. Slope is negative, so acceleration is backwards.

Accelerating (speeding up)

Position time graph with object starting ahead of origin. Moving backward and increasing speed. Slope is negative, but increasing over time.

Accelerating (slowing down)

Position time graph with object starting at origin. Moving forward, but slowing down. Slope positive, but decreasing over time.

Constant Velocity (backwards)

Position time graph with system initially at rest, but speeding up forwards. Slope is positive, so acceleration is forward.

Constant Acceleration (Distance vs. Time)

D=1/2AT^2

Car While Braking

D=1/2AT^2(+ViT)(car)

Constant Acceleration (Distance vs. Time)(if initial velocity is not 0)

D=1/2AT^2+ViT

Constant Velocity (Distance vs. Time)

D=VT

Car While Distracted

D=VT(car)

Car While Reacting

D=VT(car)

Constant Velocity (Velocity vs. Time)

V=A

Constant Acceleration (Velocity vs. Time)

V=AT

Rest

Velocity is zero over time, so no motion.

Constant Velocity (backwards)

Velocity time graph with an initial positive velocity. Moving forwards at a constant rate. Slope is zero, so no acceleration.

Accelerting (slowing down)

Velocity time graph with initial backward motion, but slowing down. Slope is positive, so acceleration is forward.

Accelerating (speeding up)

Velocity time graph with system initially at rest, but speeding up backwards. Slope is negative, so acceleration is backwards.

Time for Braking Applied/△v=at

Vf-Vi/A=T (constant velocity)
