What else can I help you with?
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
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 is the velocity of a bicycle if it travels 1 kilometer west in 4.1 minutes?
14.634 kilometers per hour.
What is distance divied by time?
Distance divided by time has the dimensions of speed (magnitude of velocity). The (distance an object travels) divided by (the time it takes to travel that distance) is a definition for the object's average speed.
If a car travels at a constant speed is it accelerating?
No. Acceleration is the change in velocity(speed) over a period time.=====================================Another contributor bristled:Sorry. Velocity and speed are not two different words for the same thing.Velocity means speed and direction, and acceleration means any change in velocity.If the speed is constant but the direction is changing ... like turning a corner or drivingon a circular track ... then velocity is changing, and there is acceleration.
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?
The velocity is not constant because even though the satellite is traveling at a constant speed, its direction is constantly changing as it orbits around the Earth. Velocity is a vector quantity that includes both speed and direction, so any change in direction results in a change in velocity.
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?
Yes, two objects can have the same speed but different velocity if they are moving in different directions. Velocity is a vector quantity that includes both speed and direction, so even if two objects are moving at the same speed, if they are moving in different directions, their velocities will be 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.
