Question

1. describe newton’s first law of motion.

Explanation:

Newton's first law of motion (also known as the law of inertia) states that an object at rest will remain at rest, and an object in motion will continue in motion with a constant velocity (same speed and direction) unless acted upon by a net external force. In other words, if the net force ($F_{net}$) acting on an object is zero ($F_{net} = 0$), the object's velocity ($v$) will not change. Mathematically, this can be expressed as: if $F_{net} = \sum F = 0$, then $\Delta v = 0$ (where $\Delta v$ is the change in velocity). This law helps us understand how objects behave when there is no unbalanced force acting on them, and it forms the basis for understanding the concept of inertia, which is the tendency of an object to resist changes in its state of motion.

Answer:

Newton's first law of motion (law of inertia) states that an object at rest stays at rest, and an object in motion stays in motion with a constant velocity (same speed and direction) unless a net external force acts on it. Mathematically, if the net force \( F_{\text{net}} = \sum F = 0 \), the object's velocity \( v \) remains unchanged (\( \Delta v = 0 \)).
