    Joules is unfortunately a vector because it’s over a distance in a direction. Temperature is a scalar. Sometimes scalars are better than vectors.

    Edit:Ok for those who don’t actually understand joules in its units J=KG•M2/s2 or N•D, it’s force which is a vector over a distance, this requires a magnitude and direction. This is because force is a vector and Joules is using force. All of you are starting to be confidently incorrect… Joules is a vector you can search it up.

    It’s the exposure that undermines it. Their isn’t enough exposure to real life application and examples. How many people never realise that velocity is a derivative of position over time or acceleration is a derivative of velocity over time. Or that the speed of light is a horizontal asymptote for matter.

    It’s because trigonometry is used to teach people geometry and nothing in real life application. You want basic trigonometry in real life we should use physics as a basis for why trigonometry is useful in real life. You can’t expect theory to be used in practicality when nobody has any experience.
