An object will move at constant speed until?
An object will move at constant speed until acted upon by a force.
Why do objects in space continue to move in a straight line at a constant speed?
Because there is no air in space, there is no friction to slow said object down.
Is it correct to assume a motion of constant speed?
It depends on your setting. If the net force on an object is zero than the object will move with a constant speed. It will also move with a constant speed (but not velocity!) if a force forces the object to move in a circular motion.
Why do objects go in a straight line after the centripital force is not exterted anymore?
That's just a special case of inertia. In general, objects have the tendency to move in a straight line, and at a constant speed, when no force is acting on them.
When is a body consider with constant speed?
when a body move with uniform speed
Can a car move with changing velocity while maintaining constant speed?
Constant speed around a curve is changing velocity.
What happens of there is no friction?
Objects would move with constant velocity or stay at rest.
A cyclist goes around a level circular track at constant speed. Is the cyclist's acceleration zero because her speed is constant?
No. The cyclist is moving at a constant speed, but her velocity is changing. Remember that velocity is speed with a direction vector associated with it. As speed is constant, only direction is changing. But a change in direction is a change in velocity (even if speed is constant), and this requires acceleration in that direction to accomplish the change in direction. You're on the right track, but just recall that acceleration is tied to velocity and not just speed. And note that velocity can change all the time without speed changing. Acceleration must cause the change in velocity. Consider that objects in orbit around the earth move at a pretty constant speed, but accelerate toward the earth all the time. Their speed coupled with their acceleration toward earth cause them to move in an arc - which is their orbital path.
What velocity vector will move you 200 miles east in 4 hours traveling at a constant speed?
Positive velocity will move you 200 miles east in 4 hours traveling at a constant speed.
What velocity vector will move you 200 miles east in 4 hours traveling in a constant speed?
Positive velocity will move you 200 miles east in 4 hours traveling at a constant speed.
What is an object that continues to move at a constant speed without a force?
Accelaration
What is constant speed?
Constant speed is movement at a fixed (constant) distance per unit of time. The same amount of distance is covered by the object in the same amount of time at each measurement of that same interval. An example of an object moving at a constant speed might be an object in orbit. Something up their above the drag of the atmosphere will move at a constant speed, and will continuously move around the earth at the same speed. Note that velocity is speed with a direction vector. An object in orbit will have a constant speed, but its velocity will be constantly changing because it is constantly changing the direction it is moving.
