P2.1 Motion Flashcards
1
Q
What can the four stages on a distance time graph be?
A
1) Steady speed
2) Stationary
3) Increased speed
4) Moving back to start
2
Q
What is the equation for speed?
A
Speed = distance/time
3
Q
What does the gradient represent on a distance time graph?
A
Speed
4
Q
How do you find out the speed using the gradient?
A
Gradient = vertical/horizontal = Speed
5
Q
Define acceleration
A
How quickly velocity is changing
6
Q
What is the equation for acceleration?
A
Acceleration = change in velocity/ time taken
7
Q
What is the equation for change in velocity?
A
Change in velocity = final velocity - initial velocity
