No. Inertia is the tendency of an object to maintain its velocity.

d/t=s d = distance t = time s = speed the speed is actually going to be the average speed because they are practically the same thing (and for this equation speed is the exact same thing as average speed)

mass and inertia are the same thing.

inertia is the tendency of an object to remain at rest, or to continue to move in the same direction at constant speed. [physics]

The mass of the body. The same thing is usually referred to as inertia, which is the relunctance of the body to acceleration.

velocity is a vector and speed is scalar. Velocity has magnitude and directions, with magnitude being speed. The magnitude of average velocity and average speed is the same.

Average and instantaneous speed are the same when the speed is constant during the time period you're interested in.

Average speed is an average value of speed over a given time. If your speed is constant (not changing), then your average speed will equal your speed at any given moment in time.

Average Speed is different from average speed becoz speed is particular while avera speed is the total distance divided from time

The magnitude of both can be the same.

No. Speed has no direction. Velocity is speed anddirection.

They are both the same thing and therefore travel at the same speed.

Inertia does not affect gravity, these are two entirely separate things, even though they both are produced by the same thing, which is mass. Mass creates both inertia and gravity, but inertia and gravity do not affect each other.

different on constant and instantaneous speed

Yes. Inertia is what holds an object in motion from falling faster than the object falling at the same time. Say you have a brick and a feather. Which falls faster? Neither. You see, inertia contributes with the third law of motion, meaning an object at rest will stay at rest until a net zero force acts upon it. Meaning that inertia is that net zero force keeping that object at rest still. Now, if you dropped a brick off of the building at the same time as the feather, inertia would keep the brick from falling faster than the feather because of its speed. Gravity is pulling the object toward earth and inertia is holding it back. Same for the feather except theres less inertia because of the weight of the feather.More Speed= More inertia. Keep that in mind.

Yes. If an object is moving at a constant speed the average speed and the constant speed are the same.

No. Speed and time are different things.

BecuZ average is the same limit and the other is nesting velocity

In that case, the average speed is the same as the instantaneous speed.

Average velocity equals the average speed if (and only if) the motion is in the same direction. If not, the average speed, being the average of the absolute value of the velocity, will be larger.

Distance does not affect the average speed. A car can travel 1 kilometre at an average speed of 60 km per hour, or it can travel 100 km at the same average speed.

Inertia is "rotary momentum"; an object's ability to continue spinning when a decelerating force is applied.Just as a heavy object takes more effort to stop from the same speed as a light object, so does a heavy object take more effort to stop from turning at the same speed as a light object.So assuming they are turning at the same angular velocity, the heavier one has a larger inertia. Otherwise, remember that inertia is also proportional to angular velocity.

They do have the same average speed ... it's called the air temprature. I believe you need to define average for yourself.

No, but they have to do with each other.

When it an object in space in moving it will keep moving at the same speed with the property of inertia. Then moon is an object that has inertia. Gravity keeps the moon from going off into outer space but inertia keeps the moon from crashing into the moon. Gravity and inertia have to be balanced in order for an object to remain in orbit.
