Kinematics and Mechanics Flashcards
For a displacement time graph what does a positive gradient show?
Object is moving forwards.
For a displacement time graph what does a negative gradient show?
Object is moving backwards.
For a displacement time graph what does a positive gradient and a positive value mean?
In front of the fixed point, moving away from it.
For a displacement time graph what does a positive gradient and a negative value mean?
Behind fixed point moving forwards towards it.
For a displacement time graph what does a negative gradient and a positive value mean?
In front of fixed point moving backwards towards it.
For a displacement time graph what does a negative gradient and a negative value mean?
Behind fixed point, moving backwards away from it.
On a displacement time graph how do you find velocity?
Gradient.
On a velocity time graph what is the gradient?
Acceeleration.
On a velocity time graph what is the area under the graph?
Total displacement.
For a velocity time graph what does a positive gradient and a positive value mean?
Moving forwards, speeding up.
For a velocity time graph what does a positive gradient and a zero value mean?
Changing direction from backwards to forwards.
For a velocity time graph what does a positive gradient and a negative value mean?
Moving backwards, slowing down.
For a velocity time graph what does a zero gradient and a positive value mean?
Moving forwards at a steady speed.
For a velocity time graph what does a zero gradient and a zero value mean?
Not moving.
For a velocity time graph what does a zero gradient and a negative value mean?
Moving backwards at a steady speed.
