Snemalna Knjiga Besedilo
Correct! In order for anything to be in motion, we have to apply a force.
(KICKS BALL)
Right now the soccer ball isn't moving which means it is at rest and it will stay at rest until an outside force acts on it.
(BALL IS STILL ROLLING)
After the ball is in motion, it won't stop until an outside force is applied.
Correct again! In this case, the outside force was friction with the grass
(BALL STOPS)
This box is empty which means it is easy to push. Which means I don't need that much force to push it.
But this car however has much more mass than the box, which means we'll need more force to push it.
