P2.1 motion Flashcards
1
Q
Equation for speed
A
Speed =distance/time
2
Q
Distance time graphs
A
- Horozontal line =stationary
- straight non horozontal=constant speed
- gradient=speed the steeper the slope the greater the speed
3
Q
acceleration equation
A
acceleration=change in speed/time
4
Q
Velocity time graphs
A
- Distance in triangle = base ×height/2
- distance in rectangle =base×height
- acceleration=change in speed/time
5
Q
Vectors vs scalar
A
- Vectors have a number and direction velocity
- scalars have only a number eg speed,time,distance,mass
6
