What is the science of getting ships from place place including the determining of position course and distance traveled?

Marine navigation.


Speed is the rate of change of position expressed as traveled per unit of time?

distance


In determining velocity of any object in motion Why is it important to know the distance and the time the object traveled?

Velocity is equal to distance divided by time.


Is distance directly proportional to velocity?

Distance Traveled is directly proportional to velocity. This is because velocity is the change in position over a period of time. The greater the velocity, the greater the distance traveled. For you calculus junkies, integrate velocity to get displacement.


What is the difference between actual distance traveled and straight line distance?

Actual distance travel is the total distance you actually traveled, including all the loops and curves. Straight line distance is the direct distance between the 2 places, in a straight line without a curve


What is the distance traveled by an object divided by the time in which the distance was traveled without identifying the direction traveled?

Speed describes the distance traveled by an object divided by the time in which the distance was traveled, if the direction is not specified.


What is the different distance and displacement?

Displacement is a vector quanity that measures the difference between final position and initial position. Distance is a scalar quanity the measures the total length traveled. For example, imagine you begin stationary at any location and walk along the outline of a 100ft circumference circle, returning you to your starting location. Your distance traveled will be 100 feet, your displacement will be 0 due to your initial position and final position being identical.


How is average speed sometimes different than average velocity?

Average speed is the distance traveled divided by the time traveled. Average velocity is the displacement divided by the time traveled. Displacement is change in position, or final position (df) minus initial position (di). Let's say you traveled from your home to the mall and then back again. The total distance traveled was 30 miles, and the total time driven was 1 hour. Average speed = distance traveled/time traveled = 30 miles/1 hour = 30mi/hr or 30mph. Average velocity = (df - di)/time traveled = 0 mile/1 hour = 0 mi/hr or 0mph.* *In this case the final position and the initial position are the same (your house), so the displacement is zero. Something to think about: When a Nascar driver races 500 miles around an oval track, his average speed might be 160mph, but his average velocity when he finishes the race is 0mph.


What are distance traveled and time traveled and rate of travel related?

Rate of travel = (distance traveled) divided by (time traveled)


Does displacement always equal distance traveled?

No. Displacement is how far an object is from its original position. This means that if an object traveled in a circle and returned to its original point, it will have a displacement of 0 while the distance will be whatever the circumference of the circle was. Hope that helps.


What is the formula for distance traveled?

distance traveled = speed multiplied by time taken.


An object (say car) goes from one point in space to another .After it arrives to its destination its displacement is ( ) than the distance it travelled?

No. The "displacement" is the difference in position, which is not the same as the distance traveled.
