1State the differences between scalar and vector quantities. Give example for each of quantities.
Scalar: Temperature, Time, Speed
Vector: Velocity, Acceleration, Force
11Indicate which of the following quantities are scalars and vectors respectively: mass, weight, velocity, speed, time
scalars=mass, weight, speed
vectors=velocity, time
呢兩題係咪錯架scalar and vector

✔ 最佳答案
Time and weight should be a vector since there is directionWeight is a kind of force. so other than magnitude, it also has direction

我自己係個F.5學生，都講過mechanics.
1 The difference is that vectors quantities are described by both the magnitude and direction while scalar quantities are described by magnitude only.
正如你所講:
Vector有Velocity, Acceleration, Force
Scalar有Temperature, Speed
11Indicate which of the following quantities are scalars and vectors respectively: mass, weight, velocity, speed, time
scalar: mass, speed, time
vectors: velocity, weight
Time呢樣野係平時來講係scalar，但如果用相對論來講就有可能係vector，因為佢同space有關(不太清楚)。所以正常來講time都係scalar quantity而不是vector，因為time冇direction。
Hope that i can help you!!
