A rat experiences more inertia or a elephant
Inertia is basically the tendency of an object to oppose a change in its state.
Mathematically, inertia is proportional, or even equal, to mass.
You can understand this as 'it's harder to move an elephant than a rat'.
Thus, an elephant experiences more inertia.
It is the product of mass and velocity.
the weight of a small type of elephant is around 6000 pounds on earth which is around 2600 kg mass.
now the rat mass might be around 0.5 kg maximum.
Let's guess the maximum speed of an elephant is around 100 km/hr or 50 miles/hour
so the magnitude of elephant momentum might be around 260,000 kg m/s
How fast would that big rat have to go?
0.5 * v = 260,000
v = 520,000 km/hour
That is one fast rat :)
Inertia is the resistance of an object to changes in its state of motion. It depends on the mass of the object, with larger and heavier objects having more inertia than smaller and lighter ones.
An elephant has a much larger mass compared to a rat. Therefore, according to Newton's first law of motion, which states that an object at rest tends to stay at rest, and an object in motion tends to stay in motion with the same speed and in the same direction, an elephant would generally experience more inertia than a rat. This means that it would be harder to start or stop the motion of an elephant compared to a rat due to its greater mass.
To determine which of the two objects experience more inertia, you need to compare their masses. The mass of an object can be measured or calculated using various methods, such as weighing it on a scale or dividing its weight by the acceleration due to gravity (9.8 m/s^2).
So, if you know the masses of the rat and the elephant, you can compare them to determine which experiences more inertia.
