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.

What is the difference between gravitational acceleration and acceleration?

Gravitational acceleration is simply acceleration due to gravity.


Difference between negative and positive acceration?

Positive acceleration ==> speeding up Negative acceleration ==> slowing down


Is angular acceleration proportional or inversely proportional to torque?

Proportional.For linear movement, Newton's Second Law states that force = mass x acceleration.The equivalent for rotational movement is: torque = (moment of inertia) x (angular acceleration).Proportional.For linear movement, Newton's Second Law states that force = mass x acceleration.The equivalent for rotational movement is: torque = (moment of inertia) x (angular acceleration).Proportional.For linear movement, Newton's Second Law states that force = mass x acceleration.The equivalent for rotational movement is: torque = (moment of inertia) x (angular acceleration).Proportional.For linear movement, Newton's Second Law states that force = mass x acceleration.The equivalent for rotational movement is: torque = (moment of inertia) x (angular acceleration).


How are constant speed and constant acceleration different?

There is a huge difference between constant speed and constant acceleration. Constant speed is when the object is travelling constant, no change in its velocity and acceleration or in other words no extra force to speed up. Constant acceleration when the object is acceleration constant, it means that the speed of the object is change at the same rate each second. The acceleration rate at which the object is travelling is constant. for example, when a car is stationary at a traffic light and it starts acceleration, picking up speed but the rate of acceleration will not constant because the amount of force applied differs each second due to the acceleration rate.


What is the difference between Average Speed and Instantaneous Speed?

Suppose you accelerate in your car from stopped to 50 km.hr-1. When you were stopped your instantaneous speed was zero. At the end of the period of acceleration your instantaneous speed was 50 km.hr-1. If your rate of acceleration was constant then your average speed was 25 km.hr-1.

What is the relation of the force and inertia?

The greater the inertia, the greater is the force required to produce a constant acceleration.(F=ma). But in general, acceleration is not taken constant, in this case, there is no relation between force and inertia.


What is the difference between inertia and mass?

Mass refers to the amount of matter in an object, while inertia is the resistance of an object to changes in its state of motion. Inertia depends on mass - the more mass an object has, the greater its inertia.


Why is the acceleration is faster in small objects than in large objects?

The difference is due to inertia. Inertia is the resistance to a change in motion (acceleration). A more massive object will have greater inertia, and therefore a greater resistance to a change in motion, resulting in a slower acceleration. A less massive object has lower inertia, and therefore less of a resistance to a change in motion, resulting in a faster acceleration.


What is the relationship between mass and inertia of an object?

The inertia of a body can be defined as the relunctance of a body to acceleration. The mass of a body can be defined as a measure of the inertia of a body. This is because acceleration = resultant force / mass. So, if mass is greater, the less will be the acceleration of the body and hence the greater the inertia.


Is angular momentum always parallel to angular acceleration?

momentum is product of moment of inertia and angular velocity. There is always a 90 degree phase difference between velocity and acceleration vector in circular motion therefore angular momentum and acceleration can never be parallel

What are the difference between velocity and acceleration?

Acceleration is the rate of change of velocity.


What is the difference between newton's first law and law of inertia?

There is no difference. They are the same.


What is the difference between force and inertia?

A force is a push or a pull. Inertia is unchanging state (mass or velocity)


How are the terms inertia and motion related?

The 1st modern theory of inertia was theorized by sir Isaac Newton in 1687. He said inertia = mass * acceleration. Acceleration is = to motion in this instance.
