2. 1D Motion / Kinematics

A car accelerates from an initial speed of $20\text{m/s}$ to a final speed of $26\text{m/s}$ at a constant acceleration of $1.4\text{m/s}{2}^{}$. How much time does it take for the car to reach this final speed?

In the context of motion in one dimension, is it possible for an object to have a constant $v$ while its $a$ is not $0$?

Which of the following is the correct SI unit for acceleration in kinematics?

Which of the following best describes the difference between $v$ (velocity) and $a$ (acceleration)?

Acceleration is a vector. What does that mean?$a$ is a $\overrightarrow{a}$.

A car travels in a straight line east, changing its speed at different times. Is it possible for the car to have an acceleration directed $\mathrm{west}$ during this motion?

Which of the following best describes the physical quantity defined as the rate at which $v$ changes over $t$?

When an object is released with an initial velocity upward near $E{a}^{r}th$'s surface, in what direction does it accelerate?

A pike accelerates from rest to a speed of $8m/s$ in $0.4s$ during a strike. What is the acceleration of the pike during this strike?

What is the acceleration of a car that maintains a constant velocity of $100km/h$ for $10s$?

Why is slowing down considered $acceleration$ in physics?

Which of the following is the cause of an acceleration?
