Velocity and Acceleration Flashcards
1
Q
Velocity
A
Speed in a given direction
2
Q
Speed
A
How fast you are travelling
3
Q
Distance
A
How far you travelled
4
Q
Displacement
A
Distance in a certain direction
5
Q
Acceleration
A
The rate of change of velocity. It is a measure of how fast an object is speeding up
6
Q
Is acceleration a scalar or vector quantity? Why?
A
Vector: the direction of the acceleration is the direction in which the velocity is increasing
7
Q
Equation for acceleration
A
acceleration (m/s2) = change in velocity (m/s) / time taken (s)
a= (v-u) / t
