Acceleration is a change in either the magnitude or direction of velocity, over time. http://en.wikipedia.org/wiki/Acceleration

What is inertia and what does it measure?

Inertia is the tendency of an object to resist changes in its motion. It measures an object's resistance to acceleration, meaning that the more inertia an object has, the harder it is to change its state of motion.


When forces cancel each other and do not change an object's motion it is?

When forces cancel each other out and do not change an object's motion, it is in a state of equilibrium. This means that the net forces acting on the object are balanced, resulting in no acceleration or change in velocity.


What is needed to change an object's state of motion?

With changing the "state of motion", I assume you want to change the velocity. What you need here is a force, applied on the object. The amount of acceleration is given by Newton's Second Law.


When forces act on an object without changing its motion what is that called?

When forces act on an object without changing its motion, it is called a state of equilibrium. This means that the forces are balanced, leading to no acceleration or change in velocity of the object.


What is the definition of resistance to acceleration?

Inertia resists acceleration. Inertia resists a change in the state of motion of a particle or rigid body. For instance, in order for the state of motion of an object to change, there must be a net external force exerting on the object, which is defined as mass times acceleration. Resistance to this net external force would therefore have to resist the object's acceleration, and that is inertia.

What can change the state of rest or motion of an objec?

Force, can change the state of motion through acceleration a=Force/m.


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 is a change in the state of motion evidence of?

A change in the state of motion of an object indicates that a force has been applied to it. It accelerates in response, and this appears as a change in its state of motion. It may speed up, slow down, or change direction in response to the applied force.


How is net force and inertia related?

Net force is the overall force acting on an object, causing it to accelerate or change its state of motion. Inertia is the resistance of an object to changes in its state of motion. The net force acting on an object is directly related to the object's inertia; the greater the net force, the greater the acceleration or change in motion, and the object's inertia will determine how easily it can be accelerated or changed.


Can a balanced force change the state of rest or motion of an object?

No, a balanced force does not change the state of rest or motion of an object. A balanced force keeps an object at a constant state of rest or motion, meaning there is no change in velocity.


What is a state of rest or balance?

A state of rest or balance is when an object is not in motion or actively experiencing change. It is a state of stability where all forces acting on the object are in equilibrium, resulting in no acceleration or movement. In this state, the object remains stationary or maintains a constant velocity.


The tendency of an object to resist a change in motion is called a. displacement c. momentum b. inertia d. acceleration?

The tendency of an object to resist a change in motion is called inertia. It is the property of matter by which it continues in its existing state of rest or uniform motion in a straight line, unless that state is changed by an external force.
