Technically the gas pedal controls the change in acceleration, right?
Technically it controls the amount of air and/or fuel delivered to the engine (in a gas engine, the pedal directly controls airflow; in a diesel engine it directly controls fuel flow)
Acceleration in physics terms just means a change in velocity. Velocity is speed in a given direction. The steering wheel, gas pedal, and brake pedal all accelerate the vehicle.
I remember when my calculus professor offhand mentioned these and jerk. He had a really dry sense of humor, so I didn’t realize that he wasn’t joking with us (the class) until like two semesters later.
If I remember right, it wasn’t on any test. Those tests were all problem solving, and none of the problems had derivatives deeper than acceleration. It was awhile ago though, I could be misremembering
Is it an accelerator? Or is it a jerk pedal? Technically the gas pedal controls the change in acceleration, right?
I definitely have friends
No, if there is constant pressure on the accelerator, there is a constant acceleration on the car.
The jerk comes with the rate of change of pressure on the pedal (e.g. if you stomp on it)
That would make the driver the jerk 🤔

A valve controller, yes
Acceleration in physics terms just means a change in velocity. Velocity is speed in a given direction. The steering wheel, gas pedal, and brake pedal all accelerate the vehicle.
They definitely know that, given that they know that change in acceleration is called jerk
And I had no idea what the fourth derivative was called so I had to look it up. It’s called snap or jounce.
And fifth/sixth derivatives are crackle and pop because some physicists thought it would be funny to have it be “snap crackle and pop”

So, you didn’t realise that during the unit test?

Increasing speed -> acceleration Decreasing speed -> negative acceleration Changing direction -> Vector acceleration(change in velocity)
