September 10th, 2012 Week 3 Blog
This week I am introducing the concepts of scalar vs. vector quantities, speed vs. velocity, and instantaneous vs. average. Think about these concepts as they are important to your everyday life. Compare and contrast at least one of the concepts mentioned above. If you have questions, please let me know. Remember to post an original comment and comment on someone else's blog entry.

Well instantaneous is a certain spot and average is the whole time.
ReplyDeleteInstantaneous is at a given time as to average is the overall value well its what Mrs. Ego told me(:
Deleteif Your talking about speed youre right
DeleteThat is in incorrect because instantaneous is at the exact moment something hapen.
DeleteSpeed is just displacement but velocity is displacement in a given direction. Therefore, speed would be a scalar quantity meaning its magnitude only but velocity is a vector quantity meaning its both magnitude and direction.
ReplyDeleteSpeed is actually distance not displacement.
DeleteScalar quantity is only with magnitude as vector has both magnitude and direction. With scalar you have distance, and speed. Vector have displacement, velocity and acceleration.
ReplyDeleteYup thats better than mine xD
DeleteSpeed is the scalar quantity.
ReplyDeleteFormula for speed: distance/time.
Velocity is the speed and direction.
Formula for velocity: displacement/time.
how are they similar??
DeleteInstantaneous is immediate and prompt or short term, but average is over time/long term. Like the average time a car drove in a race throughout the whole thing, but the immediate acceleration at one point of it.
ReplyDeleteThats a good example Jennifer. :)
DeleteI like how you worded this!
DeleteA Scalar quantity has only magnitude, while a Vector quantity has both magnitude and direction.
ReplyDeleteSome Scalar Quantities are: Length, Area, Volume, Speed, Mass, Density, Pressure, Temperature, Energy, Work, Power,
Some Vector Quantities are: Displacement, Direction, Velocity, Acceleration, Momentum, Force, Lift, Drag, Weight
Yes this is true samantha the difference between scaler quantity and vector Is that vector has magnitude and direction while scaler only has magnitude
DeleteYes Thats right:)Vector with magnitude and direction.
DeleteScaler :quantity that only has magnitude and vector: quantity that has magnitude and direction the only diffrence between them Is the direction:) right Ms.Ego?
ReplyDeleteI agree with you Rosa, a scalar quantity has only magnitude while a vector quantity has both magnitude and direction. I just disagree with you on how you spelled scalar(scaler).
DeleteThe difference between speed and velocity is that speed is the distance traveled in certain time (average),while velocity is the distance traveled from a certain point to end or how fast it happened (acceleration).
ReplyDeleteSpeed- is a scalar quantity which means that it only has magnitude; and its formula is S=distace/time.
ReplyDeleteVelocity- is a vector quantity which means that it has magnitude and direction; and its formula is V=displacement/time.
Same-both have the same units of meters/second.
Your response is similar to mine, but yours is more detailed! Awesome! :)

SPEED VS VELOCITY
ReplyDeleteSpeed is the distance traveled divided by the time of travel.
The formula for speed is distance/time.
Speed is a scalor quantity and measures how fast the object is moving.
Velocity is direction and speed.
The formula for displacement/time.
Velocity is a vector quantity and measures the rate of the object in which postion it changes.
Both Speed and Velocity need time to figure out and their units are meters.
I said it almost the same but a shorter response than yours.
DeleteThat is like a definition from a book or something lol
DeleteA scalar quantity is an amount or a measurement that doesn't deal with direction. Examples would be temperature, density, volume, etc. A vector quantity has both magnitude and direction. Examples would be velocity, force, etc.
ReplyDeletekind of wat i said
DeleteI like how you gave examples of each one!
Deletespeed is distance over time like a 40 yard dash in football and velocity is how fast the object going in one direction like syrup coming out of a bottle. Rashad tatum per 1
ReplyDeleteThose are good examples.
DeleteVelocity is a vector. It consists of value and direction. Speed is a scalar, it's the value of the velocity.
ReplyDeleteAna Mendoza
Speed is a scalar quantity which means how fast an object is moving while velocity is a vector quantity because it's the rate at which an object changes it's position.
ReplyDeleteWhat's the difference between them?
DeleteHow can you compare them ?
DeleteScaler & vector are the same because they both have magnitude. They differ because vector has both magnitude and direction.
ReplyDeleteGreat answer :)
DeleteSpeed is how fast an object moves velocity how fast an object changes position.Scaler & vector both have magnitude. except for vector has direction
ReplyDeleteVelocity also takes into account direction. :)
DeleteA scalar quantity is a quantity that has magnitude only, such as time, speed, and temperature. A vector quantity has both magnitude and direction such as velocity, force and momentum.
ReplyDeleteI agree with you Ernesto, you seem to understand this topic in Physics!
DeleteScalar: quantity with only magnitude
ReplyDeleteVector: quantity with magnitude and direction
Difference is that with vector there is direction included and scalar doesn't require any direction.
Similarity is they both require magnitude.
something complex put into easy words
DeleteVelocity has direction, while speed doesn't. :)
ReplyDeleteA scalar quantity can be length, mass, or temperature. While vector quaintities can be acceleration, momentum, or force.
ReplyDeletewhen you list them like this scalar seems more prominent in every day life.
Deletescalar is a quantity with only magnitude described. i don't think its as use full as vector which is similar except it has a direction. besides i see vector in real life more often such as on a high way: 35mph North.
ReplyDeleteThat's a really good example :P
DeleteSpeed VS Velocity
ReplyDeleteSimilarities: Speed Is a Scalar Quantity while Velocity is a Vector Quanitity
Difference: Speed equal to distance/time, While Velocity equal to displacement/time
scaler has magnitude but no direction unlike vector that has both magnitude and direction and we see vector more often than scaler on a daily basis
ReplyDeleteI agree with Chanchis!
Deletespeed is a rate of motion while is a vector quanity. Both measure the distance travelled over a period of time
ReplyDeleteInstantaneous speed is how fast it as at THAT moment. Average speed is how fast it went throughout the whole trip.

ReplyDeleteInstantaneous is at a given value
ReplyDeleteAverage is an overall value
Scalar is described by a magnitude and vector
ReplyDeleteis described by both a magnitude and a direction.
Well scalar is a quantity that has only magnitude and vector has magnitude and direction. The only thing thats different was that vector has direction and scalar doesnt.
ReplyDeleteI agree with you. Straight to the point.
DeleteSpeed involves the elements of distance and time.
ReplyDeleteVelocity involves the time as well, but instead of distance it takes into retrospect the displacement.
Also, speed is a scalar quantity and velocity is a vector quantity.
I dont have time to read all these comments like come on ego i dont see how you do it & how is this relating to life ? Ugh youre complicated I guess id say speed and velocity have a lot to do with driving because you sometimes have to figure out what legal speed you'd have to go to get somewhere on time ?
ReplyDeleteSpeed can only be positive and has no direction. On the other hand velocity can be positive and negative and does have a direction.
ReplyDeleteSpeed is distance/time. Velocity is displacement /time. I would say more but it's already been said :/
ReplyDeleteRolando Rodriguez: Instantaneous is when you're in a relationship and everything's going good, but something suddenly pops up changing the course of the relationship, making it go downhill. Average is the overall status of the relationship.
ReplyDeletevelocity is the distance for the starting point to the ending point.
