Speed and velocity Flashcards
1
Q
what is speed
A
speed measures how fast an object is traveling
2
Q
how is an average speed of an object defined
A
the average speed of an object is defined as the distance travelled per unit of time
3
Q
is speed a scalar or vector quantity and why
A
speed is a scalar quantity because it has magnitude, but not direction
4
Q
how do you calculate average speed
A
average speed can be calculated by dividing the total distance travelled by the time taken
Speed𝑎𝑣 (average speed) = 𝑑𝑖𝑠𝑡𝑎𝑛𝑐𝑒/𝑡
5
Q
what is velocity
A
velocity is speed in a given direction
6
Q
is velocity a vector or scalar quantity and why
A
it is a vector quantity as it has both magnitude and direction
7
Q
how do you calculate average velocity
A
average velocity can be calculated by dividing displacement over time
V𝑎𝑣= 𝑠/𝑡
