## BIG IDEAS
- A type of simple machine that allows for easier movement of objects to higher or lower elevations without directly lifting them vertically.
- The incline creates a sloped surface, which reduces the amount of force needed to move an object by spreading the work over a longer distance.
>[!note] Definition
>An inclined plane is a flat surface that is tilted at an angle to the horizontal.
### Calculating Acceleration
$a \ = \ \frac{F_{\parallel} \ - \ f_k}{m} \ = \ gsin(\theta) \ - \ \frac{\mu_k g cos(\theta)}{m}$
where $\theta$ is the angle of the incline, $g$ is the acceleration due to gravity, and $\mu_k$ is the coefficient of kinetic friction.
>[!important] Frictionless
>If there is no friction then the equation simplifies to $a = gsin(\theta)$
