how are mass and inertia related?

Answer 1

If mass increase inertia increases. Pretty simple. Thats why if a basketball is rolling at 30 miles an hour you can stop it with your hand. But if a car is rolling at 30 miles an hour you better jump the heck out of the way.

Answer 2

Inertia And Mass

Answer 3

inertia is the inherent property of every object by the virtue of which it continues to remain in its state of motion or rest until an external force is applied,that is every object resists change in its state of rest or motion.thus more the mass more will be the resistance and therfore more the mass more is the inertia
that is why it is harder to stop a truck than a car if both these bodies are moving with the same velocity

Answer 4

Inertia and Mass 1



INTRODUCTION


Mass has an effect on almost all aspects of our lives. Inertia, the resistance to change in motion, is one property of all matter that is affected by changes in mass. This can be observed in the varying resistance to motion of objects with different masses.


MATERIALS


1 kg weight
0.5 kg weight
String
Spring scale (5 N) or 2 rubber bands



WHAT TO DO



Tie a piece of string in a bow around each of the weights.
Attach the spring scale to the 0.5 kg weight by hooking it through one of the loops of the string.
Pull the weight across the table by pulling on the spring scale. Notice how much force is used.
Use the spring scale to pull the 1 kg weight across the table. Notice how much force is used.
If using rubber bands instead of spring scales and string, wrap one rubber band around one weight. Cut the other rubber band to make a straight piece. Tie the straight piece of rubber band to the one wrapped around the weight. Pull the straight rubber band to move the weight and measure how far the band had to be stretched. Repeat this with the other weight using the same rubber bands. Compare the length the band had to be stretched to move each weight.



QUESTIONS



For which weight was more force required to move it? For which weight did the rubber band have to be stretched further to just begin to make it move?
Which weight had the most inertia?
What was different about the weight with more inertia and the weight with less inertia?
How can we relate the properties of mass and inertia?



SUMMARY



Both the weights have inertia and both have mass. However, the larger weight has more inertia because mass and inertia are related. The more mass an object has the more inertia it has. The force applied from spring scale, or the rubber band, acted as the outside force to cause motion in the weights and it was easy to see that more force was needed to overcome the inertia of the heavier weight.

Answer 5

I=m*r^2
for I=inertia
m= mass
r = location of mass abt its centeroid


if any moving mass is located at a definate dist
then the force experienced by u at its centeroid is its inertia
for its tendency of being inert to all its activities.

eg a halfbucket of water when is rotataed by u by a string
u experience a force(centrifugal)to keep it in its path i.e. by the inertia of being the body in its path wd const velo
& varying direction

Answer 6

RE:
how are mass and inertia related?

Answer 7

I think you familiar with the word momentum.
if a body is running at velocity v having mass M
and another body of mass m(M>m) is also at same velocity
then the body having mass M have grater momentum than m,
that means you have to work more to stop the body of mass M
than another body having mass m.
thus mass and inertia is related with each other.

It is directly proportional to the mass. More the mass,more will be its inertia.

Answer 9

If mass is more, inertia is more.
If mass is less, inertia is less.

Answer 10

If mass increase inertia increases...good luck...
