How does the velocity of an object change when observed from a moving frame of reference?
When an object is observed from a moving frame of reference, its velocity may appear different due to the relative motion between the observer and the object. This change in velocity is known as relative velocity, and it can be calculated by considering the velocities of both the object and the observer.
What else can I help you with?
When an object is moving it shows that?
When an object is moving, it demonstrates a change in its position with respect to a reference point over time. This change in position can be observed through its displacement, velocity, and acceleration relative to the reference point.
When is velocity negative in a moving object?
Velocity is negative in a moving object when the object is moving in the opposite direction of its positive reference point.
When can you say that a moving body has diccelerated?
A moving body is decelerating when its velocity is decreasing over time. This can be observed when the speed of the body is decreasing, or when the body is moving in the direction opposite to its initial velocity. Deceleration is the opposite of acceleration, where acceleration is the rate of change of velocity, deceleration is the rate at which the speed decreases.
What 3 thing do you need to know to determine velocity?
To determine velocity, you need to know the object's speed (how fast it is moving), the direction in which it is moving (velocity is a vector quantity with magnitude and direction), and the reference point or frame of reference from which the velocity is being measured.
Does the Doppler Effect occur when both the source and observer are moving at the same velocity?
No, the Doppler Effect occurs when there is relative motion between the source of the wave and the observer. If both the source and the observer are moving at the same velocity, there won't be any change in the observed frequency of the wave.

Acceleration can be defined as the rate at wich velocity?
Acceleration is observed when velocity changes with respect to time. For instance, at t0 an object may be moving with a velocity of 2. At t1, it could be moving with velocity of 4, which means that it has doubled its velocity; thus accelerating. This can also be observed in reverse, where at t0 the velocity is 4 and at t1 the velocity is 2. The object then has decelerated, or has slowed down with respect to change in time.
When is velocity negative in a moving object?
Velocity is negative in a moving object when the object is moving in the opposite direction of its positive reference point.

If a bird hovers inside a train whilst that train is moving then presumably it is travelling at the same speed as the train Why is this and why is it not thown to the back of a carriage?
What pushes us back is a change in velocity (i.e., an acceleration), not the velocity itself. You might as well say that the train is stationary, and that planet Earth is moving under the train. In outer space, there is no fixed reference point; and it doesn't make sense to speak of the "real" velocity. A velocity must always be indicated with relationship to some reference point. Using the Earth as a reference point is convenient, but it isn't the only option.What pushes us back is a change in velocity (i.e., an acceleration), not the velocity itself.

How do you know when an object is moving?
An object is moving if its position changes with respect to a reference point over time. This change in position can be observed through visual cues, such as seeing the object physically move, or by using tools like sensors or cameras to track its position. The object's velocity or speed can also indicate that it is in motion.
What happens to the velocity of a moving body if you change the speed at which the body is moving?
The velocity changes. called acceleration.
Rate of change of velocity of a moving object?
The rate of change of velocity of a moving object is known as acceleration. Acceleration can be calculated by dividing the change in velocity by the time taken for the change to occur. Positive acceleration represents an increase in velocity, while negative acceleration (or deceleration) represents a decrease in velocity.
Does high velocity affect rate of change of velocity?
Yes, high velocity can affect the rate of change of velocity. If an object is already moving at a high velocity, it may require more time or force to change its velocity compared to an object moving at a lower velocity due to inertia.
If a body is moving with a uniform velocity.what will be its acceleration?
If a body is moving with a uniform velocity, its acceleration will be zero. Acceleration is the rate of change of velocity, so if the velocity is constant, there is no change in velocity over time and thus zero acceleration.
