Questions: Let's define a new type of acceleration. Instead of measuring how much the velocity changes per unit time, let's study how much it changes per unit distance. So define A=dv/dx. We'll still use lowercase a to represent the usual acceleration, a=dv/dt, but uppercase A is this new 'spatial acceleration.' a) What are the units of A?

Transcript text: 7. Let's define a new type of acceleration. Instead of measuring how much the velocity changes per unit time, let's study how much it changes per unit distance. So define $A=d v / d x$. We'll still use lowercase $a$ to represent the usual acceleration, $a=d v / d t$, but uppercase $A$ is this new 'spatial acceleration.' a) What are the units of $A$ ?

Solution

Solution Steps

Step 1: Understand the Definition of Spatial Acceleration

Spatial acceleration, denoted as $ A $, is defined as the rate of change of velocity with respect to distance, mathematically expressed as $ A = \frac{dv}{dx} $.

Step 2: Determine the Units of Velocity

Velocity ($ v $) is typically measured in units of distance per unit time, such as meters per second (m/s).

Step 3: Determine the Units of Distance

Distance ($ x $) is measured in units such as meters (m).

Step 4: Calculate the Units of Spatial Acceleration

To find the units of $ A $, we need to divide the units of velocity by the units of distance: \[ A = \frac{dv}{dx} \implies \text{Units of } A = \frac{\text{m/s}}{\text{m}} = \text{s}^{-1} \]

Final Answer

The units of $ A $ are $\boxed{\text{s}^{-1}}$.
