From Newton’s second law of motion, we know that a net force is equal to mass times acceleration.

根据牛顿第二运动定律， 我们知道合力等于质量乘以加速度。

From Newton's second law of motion, we know that a net force is equal to mass times acceleration.

根据牛顿第二运动定律，我们知道结果 力等于质量和加速度的乘积。

For example in physcis: Suppose you are learning about a new law of physics, such as Newton's second law of motion.

例如在物理学中：假设您正在学习一条新的物理定律，例如牛顿第二运动定律。
