Acceleration

What is the acceleration?

0.2 m/s2

Ariana is accelerating her car at 4.6 m/s2. It took her 10 seconds to reach this acceleration. Her starting velocity was 0 m/s. What was her final velocity?

46 m/s

Which equations can be used to solve for acceleration? Check all that apply.

A D F G

Which graph would match the same type of movement that the graph shows?

A.)

____ is the rate of change in velocity.

Acceleration

If the change in velocity increases, what happens to the acceleration during the same time period?

Acceleration increases.

If velocity is positive, which would most likely yield a negative acceleration?

An initial velocity that is faster than a final velocity.

Which best depicts the data?

From 6 to 8 seconds, Elan accelerated faster than Anna.

Isla's change in velocity is 30 m/s, and Hazel has the same change in velocity. Which best explains why they would have different accelerations?

Isla had a different time than Hazel.

Which lists them from greatest to lowest change in velocity?

Kira → Diego → Dustin

Based on the graph of velocity over time, which could be the initial velocity and the final velocity for this graph?

initial = 2.5 m/s; final = 2.5 m/s

Micah knows that a car had a change in velocity of 15 m/s. To determine acceleration, Micah also needs the ___ of the total trip in seconds.

time

Which best describes the riders?

Gabriella is slowing down at the same rate that Kendall is speeding up, and Franklin is not accelerating.

Acceleration involves a change in speed and

direction.

Which most likely could cause acceleration? Check all that apply.
