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 of motion, an object at rest stays at rest unless acted upon by an external force. Whether in Earth's atmosphere, outer space, or the ocean, an external force is needed to initiate motion for an object at rest.
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. More mass means more inertia.

Answer:

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