When the velocity of an object changes, it is acted upon by a force called acceleration. This force can be caused by various factors, such as gravity, friction, or applied external forces. The acceleration of an object is directly proportional to the force applied to it, according to Newton's second law of motion.

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 is force that maintains motion?

The force that maintains motion is inertia. Inertia is the tendency of an object to resist changes in its velocity. An object in motion will continue moving at a constant velocity unless acted upon by an external force.


Inertia is the force that causes .?

Inertia is the tendency of an object to resist changes in its motion. It is the force that keeps an object at rest or in motion at a constant velocity unless acted upon by an external force.


What can cause the velocity of an object to change?

Acceleration is a change in the speed of an object (contrary to popular belief - acceleration ban be an increase or decrease in speed). Velocity of an object only changes when acted on by an external force like a push, friction or other force. Objects in motion stay in motion until acted on by an external force


If an object falls of a shelf how do you know a force as acted on it?

You know a force has acted on the object because the objects velocity has changed as the result of a force, f= mdv/dt.


When an object undergoes an acceleration?

What is the force that resists changes?

I don't think there is such a force. Your question might refer to "inertia", but of course, inertia is not a force - it is more closely related to mass.


What changes speed and direction?

Velocity is defined as a vector quantity representing both speed and direction. Acceleration is defined as the rate at which velocity changes. The acceleration of an object changes when it is acted upon by an unbalanced force.


What is inertia describe?

Inertia is the tendency of an object to resist changes in its velocity. An object at rest will stay at rest, and an object in motion will continue moving at a constant velocity unless acted upon by an external force. It is described by Newton's First Law of Motion.


What Always change the velocity of an object?

Force changes the velocity of an object by acceleration, a=F/m.


What is the tendency of an object to resist changes in their state of motion?

The tendency of an object to resist changes in its state of motion is called inertia. This means that an object will continue to stay at rest or move at a constant velocity unless acted upon by an external force.
