Conservation of Energy
2. Which of the following objects has the greatest inertia?
A feather
A tennis ball
A car
An airplane
3. An object at rest tends to stay at , and an object in motion tends to stay in with the same and in the same unless acted upon by an unbalanced .
4. The property of matter that resists changes in motion is called .
5. A force is required to keep an object moving at a constant velocity.
True
False
6. Friction is an example of an unbalanced force that can change an object's motion.
True
False
7. Describe a real-world scenario where Newton's First Law of Motion is clearly demonstrated. Explain how the law applies to your example.
8. What is the difference between an object being 'at rest' and an object moving at 'constant velocity' according to Newton's First Law?
Use the words below to complete the sentences.
9. The greater an object's , the greater its .
10. An object will only change its state of motion if an force acts upon it, causing a change in its .
