When cars are changing direction they are also changing what?
They are changing velocity. Velocity is the measure of speed and direction
If displacement is not changing as a function of time then what can we say about velocity?
If the displacement is not changing, the velocity is zero.
What is the difference between acceleration and velocity?
-- 'Velocity' is the rate at which position is changing, and the direction of the change. -- 'Acceleration' is the rate at which velocity is changing, and the direction of the change.
What is an object always changing if it is moving in a circle?
If an object is moving in a circle (like a teather ball or a planet in orbit, although orbit is not a perfect circle), then its velocity is always changing (remember that velocity is speed AND direction, and since the direction is changing, the velocity is changing). It's position is also always changing as a result of having a velocity.
Can a car move with changing velocity while maintaining constant speed?
Constant speed around a curve is changing velocity.
What must you have in a problem to adequately describe velocity?
Describe three situations in which a force changes the velocity of an object?
When cars are changing direction they are also changing what?
They are changing velocity. Velocity is the measure of speed and direction
An object traveling at a constant 20 miles per second in a circular path is changing what?
This object is changing its position, its velocity, and its acceleration.This object is changing its position, its velocity, and its acceleration.This object is changing its position, its velocity, and its acceleration.This object is changing its position, its velocity, and its acceleration.
If displacement is not changing as a function of time then what can we say about velocity?
If the displacement is not changing, the velocity is zero.
Why is acceleration zero with uniform velocity?
Uniform velocity means the velocity is not changing. Acceleration is defined as the rate of change of velocity. If velocity isn't changing, the rate of change is zero.
What is the difference between acceleration and velocity?
-- 'Velocity' is the rate at which position is changing, and the direction of the change. -- 'Acceleration' is the rate at which velocity is changing, and the direction of the change.
Can a body have constant velocity but changing speed?
No, not at all possible. But constant speed with changing velocity is possible.
How does acceleration and velocity differ?
Acceleration is the rate at which velocity is changing.
Why is velocity tangential to the path of a body?
Velocity is a vector; having direction. So, when changing direction constatly to have velocity a tangent can be drawn to the constantly changing path of the object having velocity.
What is an object always changing if it is moving in a circle?
If an object is moving in a circle (like a teather ball or a planet in orbit, although orbit is not a perfect circle), then its velocity is always changing (remember that velocity is speed AND direction, and since the direction is changing, the velocity is changing). It's position is also always changing as a result of having a velocity.
Can a car move with changing velocity while maintaining constant speed?
Constant speed around a curve is changing velocity.
The process of changing velocity?
The process of velocity change is called acceleration.
