Question

a leaf on a tree starts moving when wind blows on it. how is this an example of newtons first law of motion?

the wind exerts no net force on the leaf because it is not a push or a pull.

the wind exerts a force on the leaf, causing its motion to change.

the leaf stops moving even though the wind continues to blow.

Explanation:

Newton's first law states that an object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force. In this case, the leaf is initially at rest. When the wind (an unbalanced force) blows on it, it starts moving (its motion changes).

Answer:

B. The wind exerts a force on the leaf, causing its motion to change.
