Why is circular motion an example of constant acceleration?
Actually it isn't. In circular motion, even if you assume a constant speed (the simplest case), acceleration is towards the center. Therefore, the direction of the acceleration changes all the time - and therefore, the acceleration changes all the time.
An object has initial velocity in the upward direction a final velocity in the downward direction and undergoes constant acceleration What can you say about its average acceleration?
The average acceleration of the object will be negative since it changes direction from upward to downward velocity. The acceleration will be constant because the object undergoes constant acceleration throughout the motion.
An object that has the same speed but changes direction is?
An object that has the same speed but changes direction is considered to be accelerating. This occurs because acceleration is a vector quantity that includes changes in speed or direction of motion. When an object changes direction, it experiences acceleration even if its speed remains constant.
Should acceleration be constant?
Acceleration is not necessarily constant; it can vary based on different factors such as changes in speed or direction. In scenarios where an object experiences a constant force, acceleration can be constant. However, factors like air resistance or changes in force can cause acceleration to change over time.
Is it possible that the velocity of a body changes and its acceleration remains constant?
The definition of acceleration is: Any change of velocity, that is, speed or direction of motion. If an object is undergoing constant acceleration, then the definition says that its velocity must be changing.
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.

Can a direction of velocity of an object reverse at constant acceleration?
Yes, the direction of an object's velocity can reverse even when it is experiencing constant acceleration. This can happen if the acceleration is in the opposite direction to the object's initial velocity.
Is it true or false that acceleration can only occur when the speed of an object changes?
False. Acceleration is a measure of how quickly an object's velocity is changing, which includes changes in speed, direction, or both. So, acceleration can occur even if the speed of an object remains constant but its direction changes.
Why is it an object can accelerate while travelling at constant speed but not at constant velocity?
Acceleration means the velocity changes. Velocity is made up of speed and a direction, so if only the direction changes, the velocity still changes, and therefore there is acceleration. The typical example is moving around in a circle.
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.
Is it possible for a body to have an acceleration when moving with constant velocity?
No; acceleration means the velocity changes.No; acceleration means the velocity changes.No; acceleration means the velocity changes.No; acceleration means the velocity changes.
Are you accelerating if you are traveling in a constant direction with constant speed and explain?
No, you are not accelerating if you are traveling in a constant direction with a constant speed. Acceleration is the rate of change of velocity, so if your velocity remains constant, there is no acceleration.
