Motion Flashcards
1
Q
What is distance?
A
Total distance travelled
2
Q
What is displacement?
A
Distance as the crow flies
3
Q
What is a vector quantity?
A
Has magnitude and direction (force) velocity
4
Q
What is a scalar quantity?
A
Has a magnitude but no sense of direction (mass) speed
5
Q
Speed equation?
A
Speed = distance/time
6
Q
Typical walking, running and cycling speeds:
A
1.5 m/s, 3 m/s, 6 m/s
7
Q
What is acceleration?
A
The rate of change of velocity
8
Q
acceleration equation?
A
acceleration=change in velocity/time taken
9
Q
On a velocity time graph how do you find distance travelled?
A
Count the whole squares, then count the partial squares and half them. Then add the number of squares and times it by the area of 1 box.
