1. How is mass related to inertia?
Mass is a measure of inertia. The more mass an object has, the more inertia it has. Mass can also be described as how much inertia an object has.
2. What is Newton's 1st law of motion?
An object in motion tends to stay in motion and an object at rest tends to stay at rest; unless acted on by an outside force.
3. What is Newtons 2nd law of motion?
The force required to accelerate an object is directly proportional to the objects mass.
4. What is Newtons 3rd law of motion?
Every force has reaction force
5. How is force related to acceleration?
force is how much you have to push on something to make it accelerate. The more you want to accelerate an object, the more force you have to apply.
6. How is mass different form weight?
Mass is a measure of inertia, weight is a measure of how gravity affects an object, based on the amount of mass
7. What is equilibrium?
Balance
8. What are the 2 types of equilibrium and how are they different?
Dynamic is any state in which an object is moving but theres no net force
