Question

i. newtons first law of motion 1. newtons first law of motion is also known as the law of a. newtons first law says that an object that is not moving, or is at b. an object that is moving will keep moving with constant and in the same unless force acts on that object. 2. what is inertia? 3. what property of an object determines how much inertia it has? 4. which of the following has more inertia? a. bowling ball or tennis ball b. hammer or feather

Explanation:

1. Newton's first law of motion states an object at rest stays at rest and an object in motion stays in motion with a constant velocity unless acted upon by an external force. It is also known as the law of inertia.
2. Inertia is the tendency of an object to resist changes in its state of motion.
3. The mass of an object determines how much inertia it has. Greater mass means greater inertia.

4 - 5. Among bowling ball, tennis ball, hammer and feather, the bowling ball and hammer have more mass compared to the tennis ball and feather, so they have more inertia.

Answer:

1. a. Newton's first law of motion is also known as the law of inertia.
2. a. An object that is not moving, or is at rest, will stay at rest and an object that is moving will keep moving with constant velocity unless a force acts on that object.
3. The mass of an object determines how much inertia it has.
4. a. Bowling ball has more inertia compared to tennis ball as it has greater mass.
5. b. Hammer has more inertia compared to feather as it has greater mass.
