Question

Assuming all objects are moving with the same velocity, which statement describes the object with the smallest inertia?

A. A driver continues forward after his car takes a sharp turn.
B. A bowling ball rolls across a street and into a large soccer field.
C. A pebble is thrown in space and continues in a straight line.
D. An avalanche of snow falls down a steep mountain side.

Answer 1

C:A pebble is thrown in space and continues in a straight line.

Step-by-step explanation:

Thanks for the question this one is quite simple actually.

In space since there is less gravity this means the small pebble with be slower (Small since the name of it is pebble and not rock).

Now it is asking us what the slowest inertia would be which this means speed

A: This is wrong because it is a car with a x velocity

B:This is also wrong because the bowling bar is also going x velocity as the car

D:An avalanche of snow goes down a STEEP hill with the same x velocity as everything else

C:This is the correct answer because the gravity in space is different and this makes the small pebble very slow inertia wise until it would reach something like Earth's atmosphere

Answer 2

C. A pebble is thrown in space and continues in a straight line.

Step-by-step explanation:

Here it is given that the property of inertia is totally depends on the mass of the object.

Here it is given that all the objects given here is moving with same speed

So here the speed will be same and we need to find the correct statement which will have least inertia.

So smallest inertia is corresponding to the smallest mass

So here we can say that the correct answer will be

C. A pebble is thrown in space and continues in a straight line.

Because rest other given examples are of more mass due to which they all have more inertia then pebble.

Also inertia does not depends on the speed so correct answer is as stated above
