What is true if an object moves in the same direction and at a constant speed for 4 hours?
If an object moves in the same direction and at a constant speed for 4 hours, then the distance it travels will be equal to speed multiplied by time. The object's velocity will remain constant, and its displacement will be in the same direction as its motion.
If a car moves with a constant speed does it also moves with a constant velocity?
Not necessarily.Speed is a scalar measurement that only measures magnitude.Velocity, on the other hand, is a vector measurement and adds the important distinction of a direction.A car rounding a curve may be going the same speed, but its velocity is constantly changing throughout the curve because its direction keeps changing.
When an object moves with constant velocity what happens?
Constant velocity means that the object's speed is constant, and it moves in a straight line, i.e. the direction of its motion is also constant. When an object moves in a manner consistent with this description, probability dictates that sooner or later, it bumps into something.
Which object has a constant speed?
a car traveling the speed limit
Why the speed of an object is constant while the velocity is not?
This is not always the case. But if an object moves in a circle, at constant speed, its velocity will change. Velocity is a vector - consisting of the magnitude (the speed), and a direction. So by definition, if the direction changes, the velocity changes - you have a different vector.

If A car moves at constant speed also moving at constant velocity?
Not necessarily. Constant velocity also means no change in direction.

What changes as an object moves with a constant acceleration?
During constant acceleration, either the object's speed changes at a constant rate, or the direction of its motion changes at a constant rate, or both.
A merry-go-round horse moves at a constant speed but at a changing?
. . . velocity, because one of the components of velocityis the direction of the speed.

How can acceleration occur when speed is constant?
Acceleration is the rate of change of velocity. Even if an object's speed is constant, acceleration can still occur if the direction of the object's motion changes. For example, when an object moves in a circle at a constant speed, it is undergoing acceleration towards the center of the circle due to the change in its direction of motion.
Which example describes constant acceration due only to a change in direction?
Centrepetal force-orbits E.G. Earth orbits the sun at a constant speed but also changes its direction, thus its velocity. This means that the almost constant change in velocity causes there to be a constant acceleration because of the change on direction.
Is something accelerating with a constant speed?
That is possible, for example, if an object moves around in a circle. In this case, the velocity changes all the time; the speed does not.
When does a car move at a constant speed?
A car moves at a constant speed when the acceleration is zero. This means that neither the speed nor the direction of the car is changing. Once all external forces are balanced and there is no net force acting on the car, it will continue to move at a constant speed.
