Are you accelerating if you are traveling in a constant direction with constant speed and explain?
If you are traveling at a constant speed with changing direction there is a change in velocity, so you are accelerating.
What is the change in velocity other than speed what else?
change in velocity can also occur with change in direction as it is a vector with speed and direction; so a satellite may have constant speed but remaining in orbit has a centripetal acceleration; its direction is changing.
Is acceleration a change in the position of an object?
Yes. Acceleration is a change in velocity. As velocity is a vector (direction and speed) changing either the speed or direction will change the velocity and thus be an acceleration (or decelleration)
How can velocity change without changing the speed?
Consider velocity as consisting of a speed, and a direction. If any of the two changes - that is, if either the speed or the direction changes - then the velocity changes.
What control on a car can cause a change in velocity at constant speed?
The steering wheel can change the car's direction of motion, without changing speed.
Is changing direction really the same as changing speed?
No. It is possible to change direction without changing speed. However, it is not possible to change direction without changing velocity.
If you speed is not changing but your direction is changing are you accelerating?
Yes; acceleration is any change in velocity - speed, or direction.
How can you accelerate if your speed does not change?
A change in the vector or direction that you are traveling is considered an acceleration; even if you don't change speed. This would be the case for going around in a merry-go-round, e.g. You are accelerating (changing direction), but the speed is constant (velocity is changing).
Why does a change of speed produce a change in direction?
It doesn't. For example, you can go in a straight line, and speed up or slow down, without changing direction. And if there is both a change in direction and a change in speed, the change of speed wouldn't be the CAUSE for a change in direction. (On the other hand, both can be caused by a force applied to an object.)
Are you accelerating if you are traveling in a constant direction with constant speed and explain?
If you are traveling at a constant speed with changing direction there is a change in velocity, so you are accelerating.
Why acceleration produces at constant speed?
Acceleration by definition is a change in speed, direction, or both. If the speed is constant, the direction could still be changing. You can feel a change in direction, therefore you can feel acceleration even if the speed is constant.
What is the change in velocity other than speed what else?
change in velocity can also occur with change in direction as it is a vector with speed and direction; so a satellite may have constant speed but remaining in orbit has a centripetal acceleration; its direction is changing.
How does energy create motion and change?
This can involve changing the shape of matter, or changing the speed or direction of an object.

Is it possible for a body to have acceleration if the speed is constant?
Yes. Acceleration by definition is a change in speed, direction, or both. If the speed is constant, the direction could still be changing. You can feel a change in direction, therefore you can feel acceleration even if the speed is constant.
