A body travels with velocity v1 for time t1 second and with velocity v2 for time t2 second in the same direction find the average velocity of the body?

Average speed = (total distance) / (total time) = (v1t1 + v2t2) / (t1 + t2)

What is the property of an object that travels the same distance each second?
Such an object is said to travel at a constant speed. If it doesn't change direction, it is also said to travel at constant velocity.
What is the deffinition of velocity?
Velocity is the speed of an object in a given direction. It is typically measured in meters/second.
Compare and contrast acceleration and velocity?
-- "Speed" is the rate at which distance changes. -- "Velocity" is speed along with the direction of motion. -- "Acceleration" is the rate at which velocity changes, including the direction of the change.
Compare and contrast velocity and instantaneous speed?
velocity is just a general term for speed (it could be average velocity or instantaneous velocity). Instantaneous velocity/speed (same thing) is the speed at that second. If you are familiar with calculus, it is the derivative of the position graph. Whereas average velocity is how fast the object is going in, for example, 1 hour, it is the speed that is maintained the whole hour (or the average) Instantaneous would be that at the second, at for example t=1.425, the speed is 24m/h . something along those lines
The speed and direction of a moving object determines the what of an object?
You might be referring to velocity. It is a vector physical quantity and both speed AND direction are required to define it. One can also consider velocity as the rate at which an object changes position.
What is the average velocity of an object that travels 6 meters north in 2 seconds and then travels 3 meters east in 1 second?
3.00 m/s
Does Light have a speed or a velocity speed of light or velocity of light?
Light travels at the speed of light. There is no general velocity of light because velocity is a vector quantity, it also contains a direction and there is no preferred direction for light rays in general. Another answer: The speed of light has been calculated to be 186,000 miles per second.
The body travels 2mts in first 2 seconds and 2.2mts in next four seconds what will be the velocity at the seventh second?
heres the average 2.2 seconds
What is the property of an object that travels the same distance each second?
Such an object is said to travel at a constant speed. If it doesn't change direction, it is also said to travel at constant velocity.
What is the average acceleration of car if it travels in a straight line in one minute and it attains a velocity of 40 meters second second and it finally?
There is not enough information to answer the question. The initial velocity of the car is not given. Also, the "it finally" at the end of the question does not make sense.
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 deffinition of velocity?
Velocity is the speed of an object in a given direction. It is typically measured in meters/second.
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.
If a helicopter descends at a rate of 8 feet per second what is the speed and velocity?
When you talk about speed, the direction is irrelevant (scalar quantity); when you talk about velocity, the direction is of interest (vector quantity). Therefore, the speed is 8 ft/sec., and the velocity is 8 ft/second in a downward direction.
How do units for speed and velocity compare?
The units are the same (metres per second) except that the velocity also has the direction of motion associated with it.
How are speed and velocity different?
Speed is the distance travelled in a given period of time and is measured in metres per second or miles per hour (ie 'distance' per 'unit of time'). It is always a positive number. Velocity, however,, is the sppeed of an object in a given direction. So that if you define ''forwards' as a positive velocity, then if the object travels 'backwards', that would be classed as a negative velocity. So, if a car travels forwards, say, at 30 mph, its speed will be 30mph and its velocity will also be 30mph. However, if the car returns at the same speed, its speed will still be 30mph but its velocity will be - 30mph (minus 30mph) as the car is travelling in the opposite direction. This may seem a pointless exercise, but in equations of motion that involve speed, velocity, accceleration, time and so on, the direction of travel is important and so the velocity is used rather than speed. The concept of velocity is used in space travel, satellite technology, calculating flight paths, calculating missile trajectories and so on and so direection of travel - and hence velocity - is of vital importance.
Is meters per second a way to express units in velocity?
No, velocity is a vector, not a scalar. Metres per second is a way to express speed but to express velocity you also need a direction.
