Question

1. without changing its mass, how could you increase the acceleration of a baseball? 15. a young child probably doesnt know the terms “force”, “mass”, or “acceleration”. how could you explain newtons 2nd law to a young child without using these words?

Explanation:

1. According to Newton's second - law $F = ma$ (where $F$ is force, $m$ is mass and $a$ is acceleration), when $m$ is constant, increasing $F$ will increase $a$. So, apply a greater push or pull on the baseball.
2. You can say that when you want to make a toy car (like the baseball) go faster (speed up more), the harder you give it a push or a pull, the faster it will start moving. And if the toy car is heavier (more stuff inside it), it's harder to make it speed up.

Answer:

1. Apply a greater force on the baseball.
2. Explain that the harder you push or pull something, the faster it starts moving, and if it's heavier, it's harder to make it speed up.
