The unit for acceleration is
m
s
m/s
m/s²
The formula for acceleration is
a = Δd/Δt
a = Δt/Δv
a = Δv/Δt
a = Δt/Δd

A car is moving from left to right when it suddenly slams its brakes. What is the direction of velocity and acceleration?
Velocity and acceleration both left to right
Velocity and acceleration both right to left
Velocity is right and acceleration is left
Velocity is left and acceleration is right
In uniform acceleration,
velocity changes by the same amount every second
velocity changes exponentially as time increases
velocity does not change
velocity does change, but it is not consistent
Acceleration due to gravity is equal to

0.125 m/s²
8.0 m/s²
-8.0 m/s²
16 m/s²
A car with a velocity of 22 m/s is accelerated uniformly at the rate of 1.6 m/s2 for 6.8 s. What is its final velocity?
-11 m/s
2.0 m/s
30. m/s
33 m/s
Marco is looking for a used sports car. He wants to buy the one with the greatest acceleration. Car A can go from 0 m/s to 17.9 m/s in 4.0 s; car B can accelerate from 0 m/s to 22.4 m/s in 3.5 s; and car C can go from 0 to 26.8 m/s in 6.0 s. Rank the three cars from greatest acceleration to least, specifically indicating any ties.
A = B > C
B > A > C
B > C > A
B > A = C
