Acceleration is a vector quantity, meaning it has both magnitude (change in speed) and direction. When an object accelerates, it can be due to a change in speed, direction, or both. For example, when a car speeds up, slows down, or turns, it is experiencing acceleration because its velocity (speed and/or direction) is changing.
What else can I help you with?
In science acceleration refers to increasing speed decreasing speed or changing what?
Acceleration in science refers to the rate of change of an object's velocity, which can involve increasing speed, decreasing speed, or changing direction. It is a vector quantity that describes how an object's motion is changing over time.
How does the direction of acceleration affect the directions of motion?
The direction of acceleration affects the direction of motion by causing a change in velocity. If the acceleration is in the same direction as the velocity, the speed of the object increases. If the acceleration is opposite to the velocity, the speed decreases, and if the acceleration is perpendicular to the velocity, the object changes direction without changing speed.
True or false acceleration is a change in motion?
'Acceleration' is a change in the speed and/or direction of motion.
Can there be acceleration in the body even when the body is not speeding up or slowing down?
Yes. Acceleration is change in velocity. Velocity is either change in speed or change in direction. If you fix the speed, change in direction can account for change in velocity, i.e. acceleration.
What is meant by positive acceleration and negative acceleration?
Positive acceleration = speeding up; speed increasing in the direction you're moving.Negative acceleration = slowing down; speed decreasing in the direction you're moving,or speed increasing in the opposite direction.

How is acceleration related to the change in speed?
A change in speed (and/or direction) is acceleration.
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.
Can a body have zero velocity and still acceleration?
No. A velocity indicates a speed and direction. An acceleration is a change in speed or direction.
True or false acceleration is a change in motion?
'Acceleration' is a change in the speed and/or direction of motion.
What is the rate at which speed or direction changes?
Acceleration
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.

Yes. Acceleration is change in velocity. Velocity is either change in speed or change in direction. If you fix the speed, change in direction can account for change in velocity, i.e. acceleration.
Acceleration is a change in what?
speed or direction
If the speed of the light and radius of earth are taken as speed and length what is acceleration?
Acceleration is a change in speed or direction of motion. Youhaven't said anything about changes of speed or direction.
What is meant by positive acceleration and negative acceleration?
Positive acceleration = speeding up; speed increasing in the direction you're moving.Negative acceleration = slowing down; speed decreasing in the direction you're moving,or speed increasing in the opposite direction.
