If the sum of all forces on an object is zero, then the object remains in constant,

uniform motion.

'Constant uniform motion' means motion in a straight line at a constant speed.

The physical description of such motion is "constant velocity".

"Rest" is just constant velocity with a speed of zero.

If the sum of all forces on an object is NOT zero, then the object's velocity must

change. The change may consist of speeding up, slowing down, or turning in a

different direction.

If the sum of the forces is in the same direction as the object's motion, then

the object must speed up.

What are the condtions for an object to stay at restto keep moving at constant velocity or to move with increasing velocity?

The Condition of Equilibrium, Force equal zero, is the condition of an object at rest or moving at constant velocity. Non-Equilibrium Condition, Force is not zero, is the condition for an object to move with increasing velocity.


What are the conditions for an object to stay at rest to keep moving at constant velocity or the move with increasing velocity?

A body is moving at constant velocity including zero at Equilibrium Condition, No change of energy or zero force. With force a body can accelerate, move with increasing velocity.


If an object is moving at unifrom acceleration what is its velocity?

Its velocity is increasing or decreasing (its velocity is not constant).


What are the condition for an object to stay at rest to keep moving at constant velocity?

The condition for an object to stay at rest or if moving, moving at a constant velocity is that the sum of forces acting on the object be zero or that no force acts on the object.


Moving at constant velocity is also moving with constant speed?

Velocity is Speed in a given direction. Moving at constant velocity is equivalent to say moving with a constant speed in a specified direction. So, moving at constant velocity implicitly means moving with constant speed.


What are the condition for an object to keep moving at constant velocity?

No resultant forces act upon it


What is acceleration when velocity is constant?

there is no acceleration if the body is moving with constant velocity


What are diifferent word for object?

a "body" "moving body" an "object" is moving with constant velocity. [OR] a "body" is moving with constant velocity.


If a car moves at constant speed also moving at constant velocity give an example?

A car moving at constant speed in a straight line is also moving at constant velocity.


What are the conditions for an object to stay at rest to keep moving at constant volocity to or more increasing velocity?

In order for an object to stay at rest it must have a constant velocity of zero. If the velocity increases, then the object will accelerate and will no longer be at rest.


What is the net force on an object moving at a constant velocity?

The net force on an object moving at a constant velocity is zero.


What is the condition in which a body moving with uniform speed has variable velocity?

Uniform circular motion. The speed is constant but the direction thus the velocity is variable.
