How does inertia work?
It is exactly the same as momentum and covered by Newton's first law of motion. Inertia is a way of expressing the force required to get an object to move from rest, or the force required to change the velocity or direction of an object in motion. Anything that has mass will have inertia - a "resistance to move or change velocity or direction of motion".
This is an object's change in motion per unit time in a specified direction?
The phrase "change in motion" is rather slippery.The size of the change in the object's position, per unit time, in a specifieddirection, is the component of its velocity in that direction.The size of the change in the object's velocity, per unit time, in a specifieddirection, is the component of its acceleration in that direction.
Is the direction of the acceleration is the same as the direction of motion of the object?
No. The direction of motion is obviously based on the direction it is moving. However the direction of acceleration is based on the direction of the forces acting on an object. If I throw a baseball to you, it is moving horizontally, from me to you, however it has the force of gravity pulling it downwards, so the acceleration would point downwards. (There's also a little air resistance which is slowing it down. Air resistance is a form of friction, and friction always opposes motion. Since it's moving forward, air resistance would pull it backwards. So the acceleration would actually be a small amount back as well as straight down.)
What describes the motion of an object where there is no change in speed or direction?
Equilibrium describes any state where the acceleration and net force are zero. This means that the velocity will not change.
What can a force do?
a force is something that you apply to an object- it can move-change shape-change direction-slow it down-make it faster
What is the resistance of an object to changes in its motion?
Inertia is the resistance of a object to change in its motion
What is the resistance of an object to changes its motion?
Inertia is the resistance of a object to change in its motion
What is the inertia of motion?
Inertia of motion is the resistance mass has to motion. It also is the resistance in change in momentum. Momentum includes two things: velocity and direction. When an object changes its velocity, the momentum of the object resists the change. Also, when an object does change its velocity, its momentum is directly changed. In general, the inertia of motion is matter's unwillingness to change velocity or momentum.
The resistance of an object to changes in its motion?
The resistance of an object to changes in its motion is known as inertia. Changes in an objects motion include changes in its speed and direction.
What is inertia mean?
is the resistance of any physical object to any change in its state of motion, including changes to its speed and direction.
What is a change in an object's motion called?
A change in speed or direction of motion is called "acceleration". If an object's speed or direction of motion changes, then the object is "accelerated".
Is velocity a change in an objects motion?
Velocity is a change in an object's motion OR direction of motion.
Can forces change an object motiin?
Yes, forces can change an object's motion. When a force is applied to an object, it can cause the object to accelerate, decelerate, or change direction. The change in motion is determined by the magnitude and direction of the force applied.

What kind of motion does the speed and direction not change?
Acceleration in motion refers to a change in speed or direction of that object's motion. So a type of motion in which speed and direction do not change is a motion in which the acceleration is constant (i.e. unchanging).
What do we call the tendency of a object to stay at rest or to stay in motion?
We use the term inertia to describe the resistance of an object to any change in its motion. If an object is not moving, it doesn't want to move. If it is moving, it doesn't want to change is speed or the direction it is moving. This is covered by Newton in his laws of motion.
When you measure an object's resistance to motion you must measure what?
Inertia is an objects resistance to change in motion. Frictional forces resist motion.
