What else can I help you with?
Can your speed and velocity ever have the same magnitude?
Speed and velocity always have the same magnitude, becausespeed is the magnitude of velocity.The difference is that velocity has a direction but speed doesn't
Can instantaneous speed ever be greater than its average speed?
yes
Do the photons that escape a quasar ever reach hyper velocity?
I am not sure what you mean with "hyper velocity". In a vacuum, photons basically travel at a single speed, known as the "speed of light".
Does a car moving around the block drives at constant velocity?
It could move with a constant speed and not at constant velocity. Because the direction is ever changing. Speed is a scalar but velocity is a vector quantity which has direction aspect too.
When ever an object is standing still which value is always zero?
Its speed, velocity, and acceleration are all zero.
Can the average speed ever equal the instantaneous speed?
When there is no acceleration or when there is constant acceleration. When either of these cases is present, the graph of velocity versus time will be linear. When there is linear velocity, the average velocity will equal the instantaneous velocity at any point on the graph.
When an object's speed changes it velocity also changes?
Acceleration, the change of velocity, occurs. DO NOT EVER CALL IT DECELERATION. That term is for the archetypal caudex ( it's latin, look it up)...Hence, acceleration includes both the increase AND decrease in the rate of change in velocity...and there you have it.
What is the fastest thing ever recorded?
Tachyon is the fastest thing ever because its slowest velocity is the speed of light! Light is the fastest thing that can be seen.
Why is during a trip a car instantaneous speed can ever be greater than its average speed?
Please ask that more clearly.
How is velocity of zero different from an acceleration of zero?
Velocity basically means how fast you are going. Acceleration means how much your speed is increasing. So if there is zero velocity that means the object is not moving. If there is zero acceleration, that means that the speed is not increasing but there is actual speed and the object is not increasing it's speed what ever that may be.
Does the instantaneous speed ever equal the magnitude of its average velocity?
Yes. For a start, this happens when the object moves at a constant velocity. Also, if moving in a straight line, even if the object changes speed there must needs be a moment when its instantaneous speed is equal to its average speed - since it cannot change speed suddenly, it must do so gradually.
How can you tell the difference between a speed and a velocity graph?
Very simply . . . you're not likely to ever see a velocity graph. At least notuntil you get into advanced engineering or science.Velocity is speed and its direction . . . more information than can be displayedon a simple graph.
