Inertia itself does not cause objects in motion to come to rest. Objects in motion tend to continue moving in a straight line unless acted upon by an external force, in accordance with Newton's first law of motion. When external forces such as friction or air resistance act upon an object, they provide a force in the opposite direction of the object's motion, eventually causing it to come to rest.

Does lighter objects have mor or less inertia then heavier objects?
Lighter Objects have LESS "inertia". Mass is physical manifestation of inertia. Mass is weight so the more mass the more potential inertia to over-come -- either to make an object move or to stop an object once it is moving. So, if a meteorite weighing 1 gram hits a space station weighing 1,000 tons the likelihood of the object causing damage is proportional to the speed of the meteorite; but if the meteorite weighs 1,000 tons (same as space station) the sheer mass alone would cause damage (regardless of movement because any movement would be too much.)
What can you say about the inertia of objects of equal masses?
Newton's conception of inertia stood in direct opposition to more popular conceptions about motion. The dominant thought prior to Newton's day was that it was the natural tendency of objects to come to a rest position. Moving objects, so it was believed, would eventually stop moving; a force was necessary to keep an object moving. But if left to itself, a moving object would eventually come to rest and an object at rest would stay at rest; thus, the idea that dominated people's thinking for nearly 2000 years prior to Newton was that it was the natural tendency of all objects to assume a rest position.
Why does the electric fan continue to rotate after it is switched off?
it is due to the inertia of motion .. a body tries to continue with the state it was in initially before an external force is applied on it either to take it in motion or to bring it at rest
How many objects should be present for a force to come into play?
A force can come into play with just two objects, as long as they are interacting with each other. The force acts upon the objects to cause a change in their motion or shape.
When an object has its motion changed the cause is generally what kind of force?
When an object's motion is changed, the cause is generally a net external force acting on the object. This force can come from interactions with other objects or fields in the environment, causing a change in the object's velocity or direction of motion.

Why is it that things that are in motion eventually come to a stop?
Inertia. If a mass is in motion, it wants to maintain it's original velocity...which is zero.

When an object's motion is changed, the cause is generally a net external force acting on the object. This force can come from interactions with other objects or fields in the environment, causing a change in the object's velocity or direction of motion.
An object at rest will remain at rest and an object in straight-line motion will remain in straight-line motion unless acted upon by a?
A force, that may come from a collision with ... Another object.
Is it true that friction is a force that opposes motion?
Yes, that is correct. Friction is the force that opposes motion between two surfaces that are in contact with each other. It acts to resist the motion and can cause objects to slow down or come to a stop.
What would happen if a planet had no inertia?
Inertia is defined by Newton's first law, "Objects in motion stay in motion, objects at rest stay at rest" If a planet had no inertia it could come to a stop or accelerate to high speeds without any force applied to it. It also would not find an orbit. Inertia is a fundamental property of the law of conservation of energy. Without it, the planet, and the universe would be quite, quite different.
What force opposes the motion of an object?
The force that opposes the motion of an object is called friction. Friction is the resistance that occurs when two surfaces are in contact with each other and can cause objects to slow down or come to a stop.
What would cause objects that have the same mass to have different amount of inertia?
Inertia is the tendency of an object to resist any change in its motion.Two objects with the same mass and same velocity will both have the same amount of inertia. However, if they have different velocities, they will have different amounts of inertia.Consider two trains, one moving at 100 kilometers per hour, and the other moving at 120 kilometers per hour. If they both brake at the same time, the slower one will come to a stop sooner than the faster train, because the faster train has more inertia and can resist more friction than the slower train.
How did isaac newton come up with the first law of motion?
Isaac Newton observed that objects at rest remain at rest and objects in motion continue moving with a constant velocity unless acted upon by a net external force. He formulated the first law of motion based on these observations and his experiments with pendulums and falling objects.
