Is unbalance force necessary to maintain constant speed?
No force is necessary to maintain constant speed.A balanced group of forces is equivalent to no force.An unbalanced group of forces is equivalent to someforce,which is capable of changing the speed of something.
What is the different between constant velocity and constant speed?
constant velocity is when you maintain speed and direction, this usually is in a straight line, and constant speed means that your speed is always constant at all times.
Since an object moving in uniform circular motion keeps a constant speed there is no force necessary to keep it in motion?
false
Can you use average speed to calculate the speed of an object that is moving at a constant speed?
Yes. If an object is moving at a constant speed the average speed and the constant speed are the same.
Why constant is used?
Constant is the speed of light and as the speed of light cannot change it is 'constant'
Can an object have constant velocity and but variable speed?
No. Velocity has two parts, speed and direction A constant velocity means that both the speed and the direction must be constant. So a constant velocity must have a constant speed.
What is non constant speed?
non-constant speed is when the speed for an object does not stay the same
What is non-constant speed?
non-constant speed is when the speed for an object does not stay the same
Since an object moving in uniform circular moyton keeps a constant speed there is no force necessary to keep it in motion?
False (apex)
If the speed of an object does not changed then the object is traveling at a?
If speed does not change then the object is moving with constant speed. when object moves in a circle its speed does not remains constant. Speed of object remains constant only if it moves along linear path.
Compare the tension of a train with constant speed and acceleration?
Unless the train is in a curve, you cannot have constant speed and constant acceleration. You either have constant speed and zero acceleration, or you have changing speed and constant acceleration. Please restate the question.
What is the difference between constant speed and speed?
Constant speed is constant velocity which means your going a certain speed in a straight line. Speed is just your speed at an exact moment also called instantaneous speed
