Question

question 9 of 10
an asteroid leaves our solar system and continues moving in the same direction at the same speed for millions of years. what allows the asteroid to keep moving?
a. force
b. acceleration
c. inertia
d. friction

Explanation:

Inertia is the property of an object to resist changes in its state of motion. According to Newton's first law, an object in motion will stay in motion with a constant velocity unless acted upon by an external force. In space, with no significant external forces like friction, the asteroid continues moving due to inertia.

Answer:

C. Inertia
