What measures speed and direction an object travels?

Velocity measures both speed and direction that an object travels. The magnitude of velocity represents the speed of the object, while the direction of velocity indicates the direction in which the object is moving.


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


What does velocity tell you about a moving object?

Velocity communicates both the speed and direction of a moving object. It provides information on how fast the object is moving as well as the path it's taking. Additionally, velocity is a vector quantity, meaning it includes both magnitude and direction.


What is the difference between instantaneous velocity and instantaneous speed?

Instantaneous velocity is a vector quantity that includes both the speed and direction of an object at a specific moment. Instantaneous speed, on the other hand, is a scalar quantity representing only the magnitude of the velocity without regard to direction.


When can you say that there is acceleration?

Acceleration occurs when there is a change in velocity, either in magnitude or direction, over time. Mathematically, acceleration is the rate of change of velocity. So, if an object speeds up, slows down, or changes direction, it is experiencing acceleration.


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.)


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).


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.


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

No, a change in velocity can also be due to a change in direction even if the speed remains constant. Velocity is a vector quantity that includes both speed and direction, so changes in either component can result in a change in velocity.


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

No, the average speed and magnitude of average velocity are not always equal. Average speed is the total distance traveled divided by the total time taken, while average velocity is the displacement divided by time, including direction. If an object changes direction during the motion, then the average speed and average velocity will differ.


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 metric unit that a wave's velocity is measued in?

The speed of anything is measured in metres per second. The difference between speed and velocity is that velocity is a vector, that is it has direction and well as magnitude. So velocity would be measured in metres per second in a certain direction.
