Acceleration is just the change of velocity per unit time, so it doesn't matter at all what the velocity is.
However, if you are talking about the amount of force you need to apply to something in order to get a certain acceleration, F=ma, and m does change with velocity (only when you take relativity into account), so the faster you go, the more force you need to apply to get the same acceleration. This effect is extremely small for velocities which aren't close to the speed of light, though.

A change in speed or direction?
A change in speed or direction is caused by a force and is called acceleration.
What kind of motion does the speed and direction not change?
Acceleration in motion refers to a change in speed or direction of that object's motion. So a type of motion in which speed and direction do not change is a motion in which the acceleration is constant (i.e. unchanging).
What 2 ways causes an object's velocity to change?
If an object's speed changes, or it heads off in a new direction, its velocity has changed. Because of friction and gravity 1. acceleration 2. deceleration 3. change of direction
What is the rate at which speed or direction changes?
Acceleration
A force can cause an object to change its speed and or direction?
A force can cause an object to change its speed or direction. A force causes acceleration, as given by Newton's equation F=ma, where f is force, m is mass, and a is acceleration. Acceleration occurs when something either changes direction, like a tether ball is accelerating when it goes around the pole, or when the objects speeds up or slows down.Forces give energy to the object it is acting on.The more mass an object has, the harder it is to move, stop, or change the speed or direction of the object.An object will not start moving unless a force acts on it.An object will not stop moving unless a force acts on it.An object will not change speed unless a force acts on it.An object will not change direction unless a force acts on it.unbalanced
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.
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.
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.
How does direction affect acceleration?
Direction affects acceleration by determining whether an object is speeding up, slowing down, or changing direction. Acceleration is a vector quantity, which means it has both magnitude (speed) and direction. Changing the direction of an object's velocity will result in acceleration, even if the object maintains a constant speed.
Can an object with constant speed be accelerating?
No, an object with constant speed is not accelerating. Acceleration is the rate of change of velocity, so if the speed of an object is constant, its velocity is not changing and therefore there is no acceleration.
How is direction of acceleration related to direction of momentum?
The direction of an object's acceleration is related to the direction of its momentum change. If an object's velocity and acceleration are in the same direction, then the object will speed up. If they are in opposite directions, then the object will slow down. If the acceleration is perpendicular to the velocity, then the object will change direction without changing speed.
What could describe the motion of an object?
The motion of an object can be described by its speed, direction, and acceleration. Speed refers to how fast the object is moving, direction indicates the path it is following, and acceleration describes how the speed or direction is changing over time.
Can an object be moving if acceleration is zero?
Yes, an object can be moving if its acceleration is zero. If the object is moving at a constant velocity, the acceleration will be zero even though the object is in motion.
What is a change in speed and direction called?
If an object is in motion, we apply the term speed to the distance (displacement) it achieves for a given unit of time. If we take speed and add a direction vector, as is asked here, we are talking about the velocity of the object.
How do you describe motion of an object?
Motion of an object is typically described by its speed, direction, and acceleration. Speed refers to how fast the object is moving, direction indicates the path it is following, and acceleration is the rate at which its speed or direction changes. These factors collectively define the motion of an object.
In what ways can a change in velocity Be an acceleration?
A change in velocity can be an acceleration when the speed or direction of an object changes. If an object speeds up, slows down, or changes its direction, then it is experiencing acceleration. Acceleration is a vector quantity that includes changes in both speed and direction.
How is speed and acceleration related?
Speed is a scalar quantity that represents the rate at which an object is moving, while acceleration is a vector quantity that represents the rate of change of an object's velocity. Acceleration can affect the speed of an object by either increasing or decreasing it, depending on whether the acceleration is in the same direction as the object's motion or in the opposite direction. In general, the greater the acceleration, the faster an object's speed will change.
