Which is the best example of Newton's First Law of Motion?

A small, lightweight ball and a large, heavy ball are dropped off the top of a very tall building. They both strike the ground at the same time.

A basketball player shoots the ball from half court. It soars toward the basket until another player taps it making it go in a different direction.

It takes you more effort to move a large box across the room than it does to move a small box across the room.

You push your little sister on the swings at the park. You push harder and she ends up swinging higher.
