Inertia is best described as:
Inertia is best described as:
- A force that acts on the body to oppose movement
- An external factor that keeps a body in motion
- A force that comes from the body's interaction with its environment
- An intrinsic property of a body to resist changes in its motion (correct)
Friction is different from inertia because:
Friction is different from inertia because:
- Inertia is a force that opposes movement, while friction is an external factor
- Friction is always in favor of movement, whereas inertia is not
- Friction is a force acting on the body, while inertia is an intrinsic property of the body (correct)
- Friction comes from within the body, while inertia acts on the body
What happens in the absence of friction or other forces?
What happens in the absence of friction or other forces?
- Friction allows an object to remain in motion forever
- Inertia causes the object to come to rest
- Inertia allows an object to remain in motion forever (correct)
- The object's speed increases indefinitely
