Which Following Vehicle Below Has Greater Inertia?

Which has greater inertia a car or a truck?

The mass of the truck is more than the car.

The inertia of truck will be more because it has more mass than the car..

How do I calculate inertia?

Translational Inertia = ma, where “m” is the mass, and “a” is the acceleration of the object. Calculate the rotational inertia or the moment of inertia by multiplying the mass of the object with square of the distance between the object and the axis, the radius of rotation.

Does inertia depend on mass?

The inertia of an object is a measure of its resistance to a change in the state of its motion. It is solely dependent on the mass of the object, with more massive objects having larger inertia and a greater tendency to resist changes to their motion.

Which has the greatest inertia answer?

Answer: (4) a 20.0-kg mass has the greatest inertia.

Which best defines inertia?

Inertia is the resistance of any physical object to any change in its velocity. … An aspect of this property is the tendency of objects to keep moving in a straight line at a constant speed, when no forces act upon them. Inertia comes from the Latin word, iners, meaning idle, sluggish.

Which has more inertia a tricycle or Jeep?

DEFINITION. Inertia refers to the quality or property of matter or an object by which it remains at rest or in uniform motion and the state of it not being moved. Among the given choices, the jeep has more inertia than a tricycle, because of its size and mass.

Why do we calculate moment of inertia?

Moment of inertia also appears in momentum, kinetic energy, and in Newton’s laws of motion for a rigid body as a physical parameter that combines its shape and mass. … The moment of inertia of a rotating flywheel is used in a machine to resist variations in applied torque to smooth its rotational output.

What is the unit of moment of inertia?

The unit of moment of inertia is a composite unit of measure. In the International System (SI), m is expressed in kilograms and r in metres, with I (moment of inertia) having the dimension kilogram-metre square.

Which of the following vehicle below has less inertia?

Of the given vehicles, a bicycle has the least mass, and hence the least inertia.

Which has more inertia a truck or scooter?

More the mass, more will be inertia. Since truck is the heaviest of all the options, therefore, it has the most inertia.

Which car has greater inertia?

busA bus has more inertia, because it has more mass. So, greater force is needed to change the state of the body of greater mass.

Do all bodies have same inertia?

Answer. all bodies does not have same inertia because inertia depends on the mass of the body. For example it is easy to push or pull or stop a empty box or a book but it is not easy to push or pull or stop a car with the same force you used on the book or box.

What does the law of inertia state?

Law of inertia, also called Newton’s first law, postulate in physics that, if a body is at rest or moving at a constant speed in a straight line, it will remain at rest or keep moving in a straight line at constant speed unless it is acted upon by a force.

Which has greater inertia?

The first Law states that all objects have inertia. The more mass an object has, the greater its inertia and the more force it takes to change its state of motion. The amount of inertia an object has depends on its mass – which is roughly the amount of material present in the object.

What does inertia mean?

Inertia, property of a body by virtue of which it opposes any agency that attempts to put it in motion or, if it is moving, to change the magnitude or direction of its velocity. Inertia is a passive property and does not enable a body to do anything except oppose such active agents as forces and torques.

Do airplanes have greatest inertia?

Answer Expert Verified The airplane has a greater inertia since it has a bigger mass which needs a bigger force in order for it to move or for it to stop. Inertia is directly proportional to the mass of the object which resist change in motion.

Does speed affect inertia?

Inertia is that quantity which depends solely upon mass. The more mass, the more inertia. Momentum is another quantity in Physics which depends on both mass and speed.
