Not necessarily. Example: an object falling only under the influence of gravity accelerates at a constant rate of about 9.8 meters per square second. Its speed, however, changes.

Is it true or false that acceleration can only occur when the speed of an object changes?
No. Acceleration is change of velocity. It occurs when an object changes speed and/or direction.
How can an object be accelerating while traveling at the same speed?
Acceleration is the rate of change of VELOCITY, not of SPEED. If the velocity changes, there is acceleration. It is enough for the direction to change.
Velocity is the change of speed andor direction of an object?
Not exactly. Velocity is the speed and direction of an object's motion.If either speed or direction changes, then the change is the object's 'acceleration'.
Why at a constant speed if an object changes its direction it is considered to be acceleration?
Acceleration is a direction plus a speed. If either changes then the acceleration changes.
An object is accelerating if its blank or speed changes?
If an object's speed is changing ... either growing or shrinking ... or the direction of its motion is changing, or any combination of these changes, then the object is said to be accelerated.
Is it true or false that acceleration can only occur when the speed of an object changes?
No. Acceleration is change of velocity. It occurs when an object changes speed and/or direction.
Velocity is the change of speed and/or direction of an object?
FALSE. Acceleration is the change of speed and/or direction of an object.

Not exactly. Velocity is the speed and direction of an object's motion.If either speed or direction changes, then the change is the object's 'acceleration'.
Is the rate at which an object changes velocity?
No, velocity is the instantaneous speed of an object, the rate of change would be the acceleration of the object.
Why at a constant speed if an object changes its direction it is considered to be acceleration?
Acceleration is a direction plus a speed. If either changes then the acceleration changes.
An object is accelerating if its blank or speed changes?
If an object's speed is changing ... either growing or shrinking ... or the direction of its motion is changing, or any combination of these changes, then the object is said to be accelerated.
When An object speeds up it has what acceleration?
For an object's speed to change (increase or decrease), the object must be accelerating. If there is an acceleration, there is a non-zero net force acting on the object.note: Velocity and speed are different. An object's velocity can change without the speed changing. Example of this is centripetal acceleration. The object's velocity changes directions, thus the velocity changes. The magnitude (or speed), however, stays the same (if only a radial acceleration is present).
Why force changes the speed of an object?
Force = Mass * Acceleration or Acceleration = Force / MassThe Mass is the mass of the object and the Acceleration is the change of speed of the object due to the Force.
What happens to the speed of an object that is accelerating?
The speed may, or may not, change. Acceleration means that the velocity changes; this means that either the speed changes, or the direction.
What is a change in an object's motion called?
A change in speed or direction of motion is called "acceleration". If an object's speed or direction of motion changes, then the object is "accelerated".
Velocity is the change of speed and direction of an object?
No. Velocity is the present speed and direction of motion.If speed or direction changes, then that's 'acceleration'.
