Forces And Motion Flashcards
1
Q
What does a horizontal line on a distance time graph mean?
A
The object had stopped.
2
Q
What is the slope on a distance time graph?
A
It is the velocity.
3
Q
What are vector quantities ?
A
It has size(magnitude) and direction(velocity).
4
Q
What quantities do scalar have ?
A
They have only size(magnitude)(as in speed).
5
Q
Give the symbols for: Change in velocity Acceleration Time taken Final velocity Initially velocity Delta
A
^v a t U ^
^= triangle
6
Q
Direction of arrows?
Size of arrows?
A
Direction of force.
Size of force.
Some things only have size and no direction they are called scalars.
7
Q
Forces occur when?
A
They have an interaction between another objects.
Forces are always in pairs.
8
Q
How do you calculate speed?
A
Distance/time = speed
Speed X time = distance
Distance/speed = time
