Can you find torque by time in moment of inertia?
Comparing linear and circular motion we can see that moment of inertia represents mass and torque represents force. So the product change in the circular momentum per unit time is torque. Circular momentum is the product of moment of inertia and circular velocity.
Explain which has greater interia- a speeding car or a jet airplane?
Inertia is basically resistance of an object to change it's state of motion. The force or moment of inertia each object has is based on one of Newton's classic laws of motion: Force = Mass X Acceleration. It would be dependant on the moment of inertia of either vehicle at the time. A 20000 kg plane moving at 1m per second has the same force as a 2000 kg moving at 10m per second.
Is the oldest and the most basic branch of physics it deals with such ideas as inertia motion force and energy?
Most Oldest branch in physics is Astrophysics(Astronomy). Inertia was developed by Newton in his time . its a good base for common day physics
What is forces and motion?
Movement or displacementForce and motion is described as everyday things that are happening all the time. More then how many you're thinking of. Did you know that you use force and motion to?by Lizzy Suaalii
What is the importance of law of inertia?
The law of inertia is more popularly known as Newton's first law of motion. And that simply says that: An object in motion tends to stay in motion or a body at rest tends to stay at rest unless otherwise acted upon by a net force. This is important in day to day life because it says that when things are moving, like you walking or your car rolling, it will take some sort of braking force to stop that motion. Conversely, if you or your car is at rest, the law says you need to exert some force to get walking or put the pedal to the floor to get the car moving. In sum you are exerting forces to stop or start motion of yourself or of objects all the time. And when you do that you are acknowledging the law of inertia.
Does speed have to do with inertia?
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.
What has more inertia a truck or soccer ball?
A truck is heavier, has more mass. So at the same speed, the more massive object has more inertia. A scientific word for inertia is Momentum, defined as mass times speed, and is equal to force times time. So a 1 kilogram mass operated on by a 1 Newton force for 1 second would move at 1 metre per second and would have a momentum of 1 kg-N.
What is any change in an object's motion called?
The change in an object's motion, is simply force.The object cannot change motion unless acted upon by an outside force. For example: If I throw a baseball, it will never stop unless acted upon by gravity (or the outside force). Or the outside force could be it smacking into a wall or your friends head.
What is the formula for newton's 1st law?
Newton has three different laws of motion. The first is the Law of Inertia, the second is the law regarding Mass, Force, and Acceleration, and the third is the law that states "for every action, there is an equal and opposite reaction." Newton's second law is the only one that comes with a formula. The formula is force equals mass times acceleration.
A force that opposes motion between two surfaces that are in contact?
First of all, if you just google the question, you will get the answer. Similarly, this question has been asked on answers.com multiple times (and answered). So maybe try that next time before asking the question. And the answer is Friction.
What is the difference between inertia and acceleration?
Inertia and acceleration both relate to Newton's laws. Acceleration is mentioned in his second law. This law states that acceleration is directly proportional to force and inversely proportional to mass. Inertia on the other hand is the subject of Newton's first law. It states that an object at rest will remain at rest until acted upon by an unbalanced force. In the same manner, and object in motion will remain in motion until acted upon by an unbalanced force. A definition of acceleration: The increase of velocity over a certain time span, usually written as meters/second^2. A definition of inertia: The desire of an object to remain at a constant velocity, or the resistance to acceleration.
If a car stops suddenly your body keeps moving because it's because of Inertia ever heard of gravity and Inertia?
Yes, some times gravity effects but inertia depends upon external force and mass of it. Gravity is also an external force but in mass, higher the mass, higher the inertia and lower the mass, lower the inertia. For suppose an elephant and human, both are running in the same speed, human takes a short time to turn himself for his mass is less and less force is applied to turn whereas in elephant, its hard for it has more mass and takes a greater force to turn.
