# PHYSICS - TERM 1 - Distance Time Graphs Flashcards

What is the x-axis and y-axis?

x-axis= time

y-axis= distance

How do you calculate the gradient?

rise/run = (y2-y1)/(x2-x1)

What is the gradient in a distance-time graph?

speed

What will the gradient be if the angle is an acute angle?

positive

What will the gradient be if the angle is an obtuse angle?

negative

What if the graph shows no steepness?

gradient=0

The ____ the gradient, the ____ the speed.

steeper, faster

What will a graph look like if;

m=0

speed=0

A straight horizontal line.

What will a graph look like if;

m=constant and positive

speed=constant

A straight line from bottom to top.

What will a graph look like if;

m= constant and negative

speed=constant

A straight line from top to bottom.

What will a graph look like if;

m=increasing

speed=increasing

(acceleration)

A convex curved line from bottom to top.

What will a graph look like if;

m=decreasing

speed=decreasing

(de-acceleration)

A concave curved line from top to bottom.
