# Explain how newton’s law of inertia describes the motion of objects.

## How does inertia relate to Newton’s first law of motion?

Newton’s first law of motion states that a body at rest remains at rest, or, if in motion, remains in motion at a constant velocity unless acted on by a net external force. … Inertia is the tendency of an object to remain at rest or remain in motion. Inertia is related to an object’s mass.

## How does inertia effect the motion of an object?

Inertia is the resistance of any physical object to any change in its velocity. This includes changes to the object’s speed, or direction of motion. … Thus, an object will continue moving at its current velocity until some force causes its speed or direction to change.

## How can Newton’s laws be used to explain how and why things move?

Newton used these laws to explain and explore the motion of physical objects and systems. These laws form the basis for mechanics. … If an object experiences no net force, its velocity will remain constant. The object is either at rest and the velocity is zero or it moves in a straight line with a constant speed.

## How do you describe the state of motion?

The state of motion of an object is defined by its velocity – the speed with a direction. Thus, inertia could be redefined as follows: Inertia: tendency of an object to resist changes in its velocity. An object at rest has zero velocity – and (in the absence of an unbalanced force) will remain with a zero velocity.

## Why is the first law of motion important?

Newton’s law are very important because they tie into almost everything we see in everyday life. These laws tell us exactly how things move or sit still, like why you don’t float out of bed or fall through the floor of your house.

## What is relation between inertia and mass?

The tendency of an object to resist changes in its state of motion varies with mass. Mass is that quantity that is solely dependent upon the inertia of an object. The more inertia that an object has, the more mass that it has. A more massive object has a greater tendency to resist changes in its state of motion.

## Does speed affect inertia?

For both interpretations, the answer is ‘yes’ since force still acts in an opposite force on anything which has mass. As you accelerate, your velocity increases and therefore mass will increase. The increase in mass will bring about an opposite force. The greater the mass, the greater the inertia.

## What causes inertia?

Some sort of a local field, maybe not our A field, is really the cause of inertia. When you push on an object a gravitational disturbance goes propagating off into either the past or the future. Out there in the past or future the disturbance makes the distant matter in the universe wiggle.

## What is the formula of first law of motion?

We can give Newton’s first law in vector form: →v=constant when→Fnet=→0N. (5.2) This equation says that a net force of zero implies that the velocity →v of the object is constant. (The word “constant” can indicate zero velocity.)

## What is meant by the term inertia?

inertness, especially with regard to effort, motion, action, and the like; inactivity; sluggishness. Physics. the property of matter by which it retains its state of rest or its velocity along a straight line so long as it is not acted upon by an external force. an analogous property of a force: electric inertia.

## What are types of motion?

In the world of mechanics, there are four basic types of motion. These four are rotary, oscillating, linear and reciprocating. Each one moves in a slightly different way and each type of achieved using different mechanical means that help us understand linear motion and motion control.

## What are the two state of motion?

The state of motion of an object is described by its speed and the direction of motion. For a body having zero speed, the state of motion is rest. For a body having a constant speed, the state of motion is uniform motion. For a body having variable speed and (or) direction, the state of motion is non-uniform motion.
