# What are the conditions for an object to stay at restto keep moving at constant velocityor to move with increasing velocity?

###### Wiki User

You have three separate situations here:

1. Object stays at rest. The force on the object is not great enough to overcome its frictional forces, or its inertia.

2. Object keeps moving at constant velocity. The object's inertia and frictional forces are exactly balancedby the Force exerted on it.

3. Object moves with increasing velocity (acceleration). The Force on the object exceeds that necessary to overcome its inertia and its frictional forces.

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.

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.

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

depending on the time acceleration can be maintained constant

velocity is the speed at which you are traveling, acceleration is the rate you are increasing or decreasing in velocity. If you are going at constant velocity, you are not increasing or decreasing speed, therefore your acceleration would be zero.-@mikesbabygurl13@

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.

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.

It moves with a constant acceleration downwards. This means that its velocity is increasing at a constant rate.

velocity = frequency x wavelength so assuming velocity remains constant (which it should) increasing the wavelength will result in a decrease in frequency.

Velocity is a constant traveling speed. Acceleration is increasing traveling speed (variation of speed over time)

No, due to acceleration its velocity goes on increasing. It is given as v = g t

No. Constant velocity implies a constant speed, AND a constant direction.No. Constant velocity implies a constant speed, AND a constant direction.No. Constant velocity implies a constant speed, AND a constant direction.No. Constant velocity implies a constant speed, AND a constant direction.

No. Acceleration IS a change of velocity - any change. When velocity increases, there IS acceleration. The acceleration itself may be increasing, decreasing, or remain constant.

If an object is sustaining a constant velocity it has 0 acceleration, because acceleration is either increasing or decreasing speed.

Yes, but only in free-fall. If I'm driving at 60 mph, I have a constant velocity, but it's not my "terminal velocity" in the sense that there is no limit to my acceleration caused by air friction. But yes, an object in free-fall reaches its terminal velocity when its velocity stops increasing (acceleration=0).

Yes. Zero velocity is a velocity; if it is always zero then it is a constant velocity.

An object can indeed change velocity when its acceleration is constant as long as its acceleration is not zero. (If an object is not accelerated, its velocity cannot change.) Recall that velocity is speed plus a direction vector. A rock is falling under the force of gravity from a mile up. Its acceleration is constant. The force of gravity is not increasing or decreasing is it? No, it is not. (That's why we call it a gravitational constant.) So the rock is operating under constant acceleration (of one earth gravity, or 1 g) and its velocity is increasing. At some point in its fall, at some exact moment in time, our rock had an instantaneous velocity of 20 meters per second down. (Down is the direction vector.)

If the constant acceleration is positive, the graph would be an exponential (x2) graph. If there is constant acceleration, then velocity is always increasing, making the position change at an ever increasing rate.
