Question

1. force must be applied to initiate motion for an object in:

a) earths atmosphere
b) outer space
c) the ocean
d) all of the above

1. the inertia that an object possesses depends on its:

a) velocity
b) mass
c) volume
d) none of the above

Explanation:

1. According to Newton's first law, an object at rest will stay at rest unless a force is applied. Whether in Earth's atmosphere, outer space, or the ocean, an object initially at rest needs a force to start moving.
2. Inertia is the property of an object to resist changes in its state of motion. The amount of inertia an object has depends solely on its mass. The more mass an object has, the more inertia it has.

Answer:

1. d) all of the above
2. b) mass
