Question

1. put a checkmark next to the description if its 1st, 2nd, or 3rd for newtons three laws of motion. an object in motion will stay in motion at the same speed and direction unless a force stops it. another word to describe this law is inertia. for every force, there is another force acting against it with the same strength. an object at rest will stay at rest unless a force moves it. the greater the mass, the less the change. the formula is force = mass × acceleration (f = ma). it states the relationship between force, mass, and the speed or direction of an object.

Explanation:

1. "An object in motion will stay in motion at the same speed and direction unless a force stops it" and "An object at rest will stay at rest unless a force moves it" along with "Another word to describe this law is inertia" are descriptions of Newton's first - law of motion which is about the concept of inertia.
2. "For every force, there is another force acting against it with the same strength" is Newton's third - law of motion which is about action - reaction pairs.
3. "The greater the mass, the less the change", "The formula is force = mass × acceleration (F = ma)" and "It states the relationship between force, mass, and the speed or direction of an object" are related to Newton's second - law of motion which quantifies the relationship between force, mass and acceleration.

Answer:

1. An object in motion will stay in motion at the same speed and direction unless a force stops it: 1st

Another word to describe this law is inertia: 1st
For every force, there is another force acting against it with the same strength: 3rd
An object at rest will stay at rest unless a force moves it: 1st
The greater the mass, the less the change: 2nd
The formula is force = mass × acceleration (F = ma): 2nd
It states the relationship between force, mass, and the speed or direction of an object: 2nd
