Wiki User
∙ 9y agoVelocity is also known as speed. Velocity occurs when two objects are changing position (in motion) with respect to each other.
Wiki User
∙ 12y agoA complete statement of velocity consists of speed (magnitude) and direction.
If either the speed or direction of motion changes, then velocity has changed.
Wiki User
∙ 10y agoIt means that after a while, the velocity is not the same as what it was previously. In physics, the rate of change of velocity is called acceleration.
Wiki User
∙ 6y agoYes. Velocity is both speed and direction. If either the speed or direction change, the velocity changes.

3 ways to accelerate?
To change the acceleration of a car: speed up, slow down or turn. Acceleration is any change in velocity. Velocity is "how fast" and in "what direction". To speed up is to accelerate (increase the velocity). To slow down is to deaccelerate (decrease the velocity) To turn is also a form of acceleration (changes the direction of the velocity).
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
The rate at which an object changes position is called what?
A change in position in a certain amount of time is called motion.
What does a object do when it accelerates?
when the motion of an object accelerates it either increases speed, decreases speed, or it changes direction.
Rate of change of the velocity of an object?
The change in velocity is just the change in velocity. The RATE of change of velocity - how quickly velocity changes - is usually called "acceleration".
How does the change in angle changes the velocity?
Velocity is speed in a direction or speed at an angle. The velocity changes when the speed or angle changes.
Is a change in speed a change in velocity?
Yes. If the speed changes, so does the velocity.
How can velocity change without changing the speed?
Consider velocity as consisting of a speed, and a direction. If any of the two changes - that is, if either the speed or the direction changes - then the velocity changes.
Does speed change with velocity?
If the velocity changes, the speed may, or may not, change. The velocity can be thought of as having two components: a speed, and a direction. It is possible to change only the direction, for example, when an object moves in a circle at a constant speed. In this case, the velocity changes, but the speed does not.
How do speed and velocity relate to acceleration?
Acceleration refers to the rate of change of velocity - how quickly velocity changes. In symbols: dv/dt. When the velocity changes, the speed may, or may not, change. For example, if an object moves in a circle at a uniform speed, its velocity is changing, but its speed is not.
If the instantaneous velocity of an object remains constand can its instantaneous speed change?
No. Speed can remain constant when velocity changes, but velocity can't remain constant when speed changes.
When does the speed of an object change?
An object's speed changes whenever the rate of change between the distance the object travels and the time it takes to travel that distance changes. Do not confuse speed with velocity; speed is scalar, and velocity is vector. Velocity can change when speed remains constant.
Does the speed of an object change?
An object's speed changes whenever the rate of change between the distance the object travels and the time it takes to travel that distance changes. Do not confuse speed with velocity; speed is scalar, and velocity is vector. Velocity can change when speed remains constant.
When an object's speed changes does it's velocity also change?
yes, speed is velocity with a direction
Can you be accelerating if you are traveling at constant speed?
Velocity is speed in a certain direction. You can keep speed the same, and if you change direction then you have changed velocity.
Can velocity of a body vary if speed of the body change?
velocity means speed of an object and in a definite direction.That shows velocity changes with speed
What changes in motion can result in a change in a change in velocity?
A change in velocity basically IS a change in motion.
