Why velocity is not constant if satellite travels with constant spped at a fixed elevatiopn?
Speed is a scalar quantity meaning it has only magnitude. Velocity is a vector meaning it has magnitude and direction. Whilst the satellite's speed is constant its direction is constantly changing. If its direction didn't change it would fly off in a straight line. Since its direction is changing, the velocity must be changing. And also since the velocity is changing, the satellite is also accelerating (towards the centre of the earth).
If a car is traveling at a constant speed but is going around a curve what can you say about the cars motion?
The velocity of the car in this case is changing (to specify velocity, you indicate a speed and a direction), therefore the car is accelerating.The velocity of the car in this case is changing (to specify velocity, you indicate a speed and a direction), therefore the car is accelerating.The velocity of the car in this case is changing (to specify velocity, you indicate a speed and a direction), therefore the car is accelerating.The velocity of the car in this case is changing (to specify velocity, you indicate a speed and a direction), therefore the car is accelerating.
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.
What is the opposite of changing direction?
The opposite of changing directions would be maintaining a course, or continuing in the same direction.
Which is the ability to maintain control while changing direction?
Agility-The ability to maintain control while changing direction
Is changing direction really the same as changing speed?
No. It is possible to change direction without changing speed. However, it is not possible to change direction without changing velocity.
When you go around a curve is your velocity changing?
Yes; although speed ( a scalar quantity) may be constant the velocity ( a vector with quantity and direction) is changing because the direction is changing

Can you control sound wave direction by changing the direction and presure of air?
You can control sound wave direction, by changing the direction and pressure of air.

If you speed is not changing but your direction is changing are you accelerating?
Yes; acceleration is any change in velocity - speed, or direction.
