7. State Newton’s 1st Law of Motion. What is it also known as?

8. Also known as the law of Inertia.
“An object at rest will remain at rest, and an object will remain in motion unless acted upon by an unbalanced force.”
Also known as the law of Inertia.

9. What is Inertia. What property does depend on
What is Inertia? What property does depend on? (What kind of object would have a high inertia?)

10. Inertia is an object’s resistance to change in its motion
Inertia is an object’s resistance to change in its motion. It depends on the object’s Mass. The greater the mass, the more resistant an object is to change – it requires more force to move.

17. You are doing your part to keep the science room clean by flipping your lab stool onto the table. The stool has a mass of 4kg. When flip the stool up, it accelerates at 2m/s2. How much force do you generate by flipping the stool? Unfortunately, NO ONE else is helping. So you stoically flip your stool and 33 others. Force?

18. F = m x a F = 4kg x 2m/s2 = 8N (for one stool) 8N x (33 + 1 stools) =
8 x 34 = 272N

25. Which has more Momentum?
A 6kg sledgehammer swung at 1.5m/s.
A 2.5kg hammer swung at 4m/s.

26. Which has more Momentum?
