P9 Flashcards
How would you find constant velocity on a vt graph?
On a velocity-time graph, a straight horizontal line indicates constant velocity.
How would you find deceleration on a vt graph?
A downward sloping line on a velocity-time graph indicates deceleration or negative acceleration.
What does a curved line on a vt graph indicate?
A curved line on a velocity-time graph indicates uniformly accelerated motion.
Final velocity = initial velocity + (acceleration * time)
What does the area under the graph indicate?
The area under the velocity-time graph represents the displacement or distance traveled by the object.
Rectangle = Area = base * height
Triangle = area = 1/2 * base * height
How would one find zero velocity on a vt graph?
A horizontal line at the zero velocity level on a velocity-time graph indicates the object is at rest.
How do you find the gradient of a slope?
The gradient (slope) of the velocity-time graph at any point represents the acceleration of the object at that time.
Change in velocity / change in time
What is the equation of a straight line on a graph
y = mx+c
What would a 0 slope look like?
A horizontal line. Y = C
What would an undefined slope look like?
a vertical line. x = c
How do you calculate the gradient between 2 points?
(y2-y1)/(x2-x1)
What is the equation for the graph of a circle?
X^2+Y^2=r^2
What is the equation for the graph of a cubic?
F(x)=x^3
What is the equation for the graph of a cubic?
