Motion graphs Flashcards
What is displacement?
Displacement is somethings distance from a particular point rather that its total distance travelled. (It can be written as x)
What is a displacement-time graph?
A graph that shows how somethings displacement changes over time.
What does the gradient show on a displacement-time graph?
The gradient of a point on a displacement time graph shows the velocity of the object at that time.
What is the equation for average speed?
Distance/Time
What is a velocity-time graph?
A graph that shows how the velocity of an object changes overt time.
What is velocity?
A vector quantity measuring how fast something moves in a specific direction. (Displacement/Time)
How do you find displacement on a velocity-time graph?
The displacement is the area under the graph.
What is a speed-time graph?
A graph that shows how the speed of an object changes over time.
What does the gradient on a velocity-time graph show?
The gradient at a specific point is the acceleration at that time.
What does the gradient show on a speed-time graph show?
The magnitude of the acceleration.
What does the area under a speed-time graph show?
The distance travelled.
What does an acceleration time graph show?
How the acceleration of an object changes over time.
What does the area under an acceleration time graph show?
The change in velocity that occurred during that time.
What is a vector quantity and what are the relevant ones?
A vector quantity is one that has both direction and magnitude. Relevant vectors are displacement, velocity and acceleration.
What is a scalar quantity and what are the relevant ones?
A scalar quantity has only magnitude. Relevant ones are distance, speed and magnitude of acceleration.
