Okay, starting off by challenging the textbook definition of force as just a push or pull. That's a good way to get us thinking critically right away.
So, even a stationary object can have forces acting on it? That's an interesting point they're making, and it definitely goes against the initial 'push or pull' idea.
Asking if there are forces on a stationary ball really highlights the nuance. If you answer 'no,' it shows how much we rely on visible motion to understand force.

The video begins by challenging the simplistic definition of force as merely a "push or pull" [0:00]. It highlights that the presence of forces doesn't automatically mean an object will move, using the example of a stationary ball on the ground experiencing balanced gravitational and normal forces [0:30, 1:01]. This illustrates that for motion to occur, a net, unbalanced force is required, as seen when the ball is kicked [1:31, 1:47].
