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

Answer 1

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.

Answer 2

The condition for an object to stay at rest or if moving, keep 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.

For an object to increase its velocity, in other words to accelerate, there has to be

a force acting on the object. The force is the one responsible for the acceleration

of the object. Recall Newton's 2nd law of motion:

F = m∙a

where 'F' is the force acting on the object with mass 'm', and 'a' is the acceleration the object experiences.

Answer 3

The condition for an object to keep moving with constant velocity is that the sum of

forces acting on the object be zero or that no force acts on the object. "Rest" is just

one kind of constant velocity ... the kind with zero speed.

For an object to increase its velocity, in other words to accelerate, there has to be

a net force acting on the object, and the force must be in the direction of the

object's motion. The force is responsible for the acceleration of the object. Recall

Newton's 2nd law of motion:

F = m∙a

where 'F' is the force acting on the object with mass 'm', and 'a' is the acceleration

the object experiences.

Answer 4

When the object is at rest, the acceleration is zero. so the net total force acting on the body from all directions should be zero. when the object is moving with constant velocity, the acceleration is zero, so in this case too, after the motion is started, the force on the body should be zero. when the velocity is increasing, some acceleration is present, so some force should be present in the direction of the motion.

These are the various cases which can be explained by the equation:

Force = Mass * Acceleration.

here the mass remains constant, so acceleration depends on the net force/

Answer 5

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.

Answer 6

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.

Answer 7

Probably due to how waves move in quantum theory. All matter is ultimately made of waves, which are in constant motion.

Answer 8

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.

Answer 9

The net force must be zero.
