Does change in the velocity of an object always indicate a change in speed?
speed=distance divided by time........Hewitt describes it as how fast something moves; the distance an object travels per unit of time; the magnitude of velocity !!... and velocity is the speed of an object and its direction of motion ; a vector quantity. SO .....YES!!!!!!!!!!!
Does a change in direction affect velocity explain?
Direction does not have to change when velocity is changed. You can move North at 10 m/s and change it to 8 m/s a second later. You would still be moving North. But since velocity is a vector, if direction changes, even though speed (magnitude of velocity) remains constant, then velocity most certainly changed, since both magnitude and direction make up the vector.
How can the velocity of an object change if the speed doesn't?
Easy answer: velocity is defined as speed in a specific direction. So, if a car is traveling at a velocity of due west, 60 miles per hour, then turns onto a road going north, the velocity has changed to due north, 60 miles per hour. But the speed has stayed the same.
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.
Which example describes constant acceleration due only to a change in direction?
In physics, acceleration is defined as a change in velocity. Velocity is the measurement of the rate (or speed) and direction of an object. Therefore, an object is "accelerating" when it changes direction while maintaining the same rate (or speed).

How does a change in speed change velocity?
due to acceleration the speed and velocity will change automatically

What is ancceleration?
Probably an incorrect spelling of "acceleration", which refers to the rate of change of velocity - how fast a velocity changes. Perhaps the above answer should read speed and not velocity, as velocity means a change of direction? i.e The car accelerated from 60 kl per hr to 70 kl per hour travelling due north, then changed direction to NNW. The change in direction is a vector.

Can an objeact have constant speed and but variable velocity?
Speed is a scalar quantity while velocity is a vector quantity.It is possible that an object can have constant speed but if speed is constant while direction of motion is changing constantly then it means that body has variable velocity.An example of this phenomena is a body moving in a circle whose speed is constant but velocity is changing every instant due to change in direction at every instant.
How can you have acceleration without a change in velocity?
Turning is acceleration, and it doesn't affect your speed. One example of this is a satellite in orbit, it is always accelerating towards the Earth due to gravity, but the speed doesn't change because it's just turning in a circle around the Earth.
What Is Velocity In Science?
VELOCITY IS THE SPEED AND DIRECTION IN WHICH SOMETHING MOVES. Velocity is the distance an object travels per unit of time, in a specific direction; velocity = distance / time, in a specific direction. The distance an object travels per unit of time, without regard to its direction of travel, is called Speed. If a vehicle travels around a curve in the road at a steady 50 kph, its Speed is staying the same but its Velocity is changing due to the change in its direction of travel. 50 kph northbound and 50 kph eastbound are the same Speeds but different Velocities.
When you are describing the rate that a race car goes around a track should you use the term speed or velocity to describe the motion?
Since velocity is speed with direction, you would use speed in reference to average rate of change of position, since the direction keeps changing. You can use velocity in reference to instantaneous speed, since a car is going in a specific direction at each instant in time.Examples:80 km/h is a speed.80 km/h due north is a velocity.
A force can cause an object to change its speed or direction?
Both, a plane flying along loses both engines lets say, it'll change direction (from horizontal to vertical) and will pick up speed until it reaches maximum velocity, due to the downward force known as gravity.
