ELI5: Why is it easy to tell the difference between film and television, even on the same screen?

Every time I'm watching TV, I find that it's relatively easy to tell whether the programme you are watching is from a film or television series, just from watching a few seconds. It's just as easy to spot whether a film is a film made for television or a film designed for cinema.

One TV programme I always thought looked cinematic was Brian Cox's "Wonders" series. Today I found out it's filmed with a camera usually used for film. So what's the difference between the cameras, and why aren't TV cameras used for film and vice versa?

Frames Per second. Movies are usually filmed at 24 FPS, which is relatively slow. Soap Operas, which are famous for being very different "looking" than most other visual media, are filmed at 48 FPS. The most recent Hobbit adaptation was filmed in 48 FPS, which led to some viewers complaining it looked like a cheap TV show or soap opera.
