When you say that a race car travels north at 100km per hour are you talking about velocity?

Yes. Velocity is a vector and therefore requires magnitude and direction: Magnitude: 100 kph Direction: North


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).


What is the plane's velocity if it travels 100 km in 90 minutes?

The definition of velocity, or at least speed, is distance/(time at speed), in this instance 10/9 km/min. (In advanced mathematics, "velocity" is a vector quantity, with both a magnitude and a direction. In that instance, a direction would also be needed but was not stated in the problem.)


What measures speed and direction an object travels?

velocity


Does change in the velocity of an object always indicate a change in speed?

speed=distance divided by time........Hewitt describes it as how fast something moves; the distance an object travels per unit of time; the magnitude of velocity !!... and velocity is the speed of an object and its direction of motion ; a vector quantity. SO .....YES!!!!!!!!!!!


One car travels due to east at 40km per h and a second car travels north at 40km per h are their velocities equal?

No. "Velocity" includes a magnitude and a direction. If any of the two are different, then the velocities are also different.


What does velocity tell you about a moving object?

Velocity tells you what speed a moving object travels at and in what direction.


Is the average speed equal to the magnitude of the average velocity justify your answer?

Yes usually and no rarely, velocity is defined as a vector, having both a direction and a magnitude (which is speed in the case of velocity). For instance 100 mph (speed) east (0o) (direction). In this form it is easy to see that the magnitude is 100 mph but mathematically to determine the magnitude of a vector you would divide the vector by its direction. 100 mph 0o / 0o = 100 mph Average speed and average velocity share the same relationship as instantaneous speed and instantaneous velocity so divide out the average direction from your average velocity to determine your average speed. If this is over a time period and you know the beginning and ending places in space your averages will simply be the difference from the starting to the ending places. So yes so long as you define speed to actually be the magnitude of the vector. However, if speed is taken without direction over time it may become something different. If an object travels along a vector with a negative magnitude its speed will not be negative but its vector magnitude will. Ex: A car travelling in reverse still has a positive speed but a compass will show it to be heading in the opposite direction of travel, a negative vector value...


Can two object's have same speed but different velocity?

=== === Since momentum is a vector and not a scalar quantity, to have the same momentum, they must have the same direction. Remember, vectors have magnitude and direction. Speed is the magnitude part of velocity. Since momentum is the product of mass (a scalar) and velocity (a vector) if two objects are moving in different directions, even if they have the same mass and speed, their momentums are different.


What is the velocity of a bicycle if it travels 1 kilometer west in 4.1 minutes?

14.634 kilometers per hour.


Distance an object travels in a certain direction in a certain time?

The velocity of the object.


What is velocity of a car that travels 120 km in 2h?

Just divide the distance by the time. To know the velocity, you would also need to know in what direction the car travels.
