What is a scalar
Size/ magnitude
What is a Vector
Size (magnitude) & direction
3 examples of a scalar?
Options could be: speed, mass, energy, time, distance
3 examples of a vector
Options could be: displacement, velocity, weight, force
How do you calculate speed?
Distance divide by time
How do you calculate distance?
Speed x time
What is acceleration
How quickly the velocity is changing
What are the 3 types of acceleration
-Speed up
-slow down
-change of direction
What’s the formula for calculating acceleration
Change in velocity divided by time (v-u/t)
What does v mean
Final velocity
What does u mean
Initial velocity
In a velocity time graph what does a straight line show?
Acceleration
What does (/) a sloped line show in a velocity time graph?
Constant velocity
What does (—) straight, flat line show in a velocity time graph?
Constant speed
What does \ down line show in a velocity time graph?
Decelerating
What is displacement
The change in positions of an object
