Sound and noise are sound pressure variations measured by an SPL meter.

SPL = Sound Pressure Level.

What changes the velocity of the object?

The velocity of object always changes with wanted or unwanted outer forces.


Velocity can change causing?

Velocity change can result in changes in an object's speed and/or direction of motion. This change in velocity can be caused by forces such as acceleration, deceleration, or changes in direction, which can affect the object's kinetic energy and momentum.


Does unbalanced forces maintain motion at constant velocity?

No. If the forces on an object are unbalanced, that means their sum is not zero, and there is a net force on the object. Since there is a net force on it, the object is accelerated, which is another way of saying that its velocity changes.


When the upward and downward forces on a falling object or changes its direction is called an?

Terminal Velocity.


What can forces cause changes in?

A force causes an acceleration. That implies that it will change: * The velocity, and * The momentum.


What causes the change in velocity?

A change in velocity can be caused by forces acting on an object. These forces can be due to interactions with other objects, such as a push or a pull, or due to internal processes like propulsion systems. Changes in velocity can also occur due to changes in direction, such as when an object turns.


What can cause velocity to change?

acceleration, due to a force the moving body is affected by. SUM[Forces] = mass * acceleration --> change in speed.


What always changes the velocity of a object?

The velocity of object always changes with wanted or unwanted outer forces.


What are the forces produced from the inside of the earth and cause sudden changes on its surface?

earthquake


A change in a moving object's direction always results in a change in its?

velocity. When an object changes direction, its velocity vector changes, even if the object's speed remains constant. This change in velocity can be caused by forces such as gravity or friction acting on the object.


When the velocity of an object changes it is acted upon by a (n)?

When the velocity of an object changes, it is acted upon by a force. This force can be due to various factors such as gravity, friction, or applied external forces. The force causes the object to accelerate or decelerate, resulting in a change in its velocity.


What happens when you have unbalanced forces acting on an object?

Then the object accelerates; its velocity changes.Then the object accelerates; its velocity changes.Then the object accelerates; its velocity changes.Then the object accelerates; its velocity changes.
