Question

1. the law of inertia > state the law of inertia. > what important idea is hidden in this law?

Explanation:

The law of inertia, also known as Newton's first law of motion, 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. The hidden important idea is the concept of a frame of reference and the idea that a force is required to change the state of motion of an object.

Answer:

• State the law of inertia: 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.
• What important idea is hidden in this law: The concept of a frame of reference and that a force is required to change the state of motion of an object.
