Notes - 4.2 Newton’s First Law of Motion: Inertia
1. State Newton’s 1st Law of Motion.
2. Why is our every day experience different from what Newton’s 1st Law states?
3. Why does an object given a push across a surface slow down? Why is this in
agreement with Newton’s 1st Law?
4. Experiments have thoroughly verified that any change in velocity (speed or direction)
must be caused by an ___________________________.
5. The property of a body to remain at rest or to remain in motion with constant velocity
is called ______________________.
6. Newton’s first law is often called _____________________________.
7. The inertia of an object is measured by its ________________.
8. Which has more mass: a kilogram of cotton balls or a kilogram of gold?
9. If you go to the Moon, which has a gravitational force one-sixth of the gravitational
force on the Earth’s surface, what changes? Your mass or your weight?
