ELI5: Why do movies shot in 24 fps seem so much smoother than 24 fps?

For example, if you run like a video game or a animation in 24 fps then it's studdery as hell. But movies and tv shows appear smooth.

Short answer: blur.

When you shoot a scene at 60 fps, you get faster shutter speed and less blur. When you shoot 24fps, you get slower shutter speed, and more blur in the shot.

Play back a scene at 24 fps which was shot at 24 fps, and there is more visible motion in each individual frame. Blur. Play back the same scene at the same rate which was shot at higher speeds, and each visible frame is sharper, making it seem as though it's stuttering.
