It involves the change in velocity, which is a vector quantity, meaning that it is also the change in speed.

Acceleration will only speed up an object True or false?
False. At least the way "acceleration" is described in physics, acceleration involves any change in velocity - so the "accelerating" object can speed up, slow down, or simply change direction.
How is it possible to be accelerating at a constant speed?
Since acceleration involves a change in velocity, and object might be accelerating even though its speed is constant.
If an object is moving at a constant velocity what do you know about its acceleration?
"Acceleration" means change of velocity. If velocity is constant, then acceleration is zero.
Is there an acceleration when an object traveling at constant velocity and why?
No. Acceleration is change of velocity / time. If there is no change in velocity, there is no acceleration.
Does a car accelerate in circular motion?
Anything in circular motion is accelerated.'Acceleration' does NOT mean 'speeding up'. It means any change in the speedor the direction of motion.Circular motion involves constantly changing direction, and that's constant acceleration.
Acceleration involves a change in what two components?
Acceleration refers to the change in velocity, which is a vector quantity, therefore, it means that acceleration can mean the change in speed or the direction of motion or both.
Why circular motion includes continuous acceleration even when the speed does not change.?
Acceleration involves a change in velocity. In the case you mention, the speed doesn't change, but the velocity does. The term "velocity" includes the direction of the movement, and the direction does change.
Acceleration will only speed up an object True or false?
False. At least the way "acceleration" is described in physics, acceleration involves any change in velocity - so the "accelerating" object can speed up, slow down, or simply change direction.
Why you don't feel when earth revolves?
In general, you can't feel speed - only changes in speed (acceleration). "Acceleration" in physics includes a change of direction. So, the Earth's orbit involves acceleration. However, the acceleration is too slow to be felt.
Do newtons make stuff move faster?
A newton is a unit of force, and a force (if unbalanced) causes an acceleration. Acceleration involves any change of velocity - not just making things faster.
How is it possible to be accelerating at a constant speed?
Since acceleration involves a change in velocity, and object might be accelerating even though its speed is constant.
If an object is moving at a constant velocity what do you know about its acceleration?
"Acceleration" means change of velocity. If velocity is constant, then acceleration is zero.
When does an object's acceleration change?
Acceleration is change of velocity / time.
What is the change in velocity over time?
acceleration a----->velocity=acceleration x time: v=a x t
Is there an acceleration when an object traveling at constant velocity and why?
No. Acceleration is change of velocity / time. If there is no change in velocity, there is no acceleration.
How do you find the acceleration?
Acceleration = (change in speed) divided by (time for the change)
How is acceleration related to the change in speed?
A change in speed (and/or direction) is acceleration.
