8.4.1 (Term 1) Flashcards
Learning objectives Describe the motion of an object by interpreting linear motion graphs (s-t, v-t, a-t) Calculate and interpret the intercepts and gradients of linear motion graphs (s-t, v-t, a-t)
What does a D-T graph represent?
A D-T graph represents displacement vs. time.
What does a V-T graph represent?
A V-T graph represents velocity vs. time.
What does an A-T graph represent?
An A-T graph represents acceleration vs. time.
What does the slope of a distance-time (D-T) graph represent?
The slope of a distance-time graph represents velocity.
What does a constant slope on a distance-time graph indicate?
A constant slope indicates a constant velocity.
What can the slope of a distance-time graph be?
The slope can be positive, negative, or zero.
What does a positive slope on a distance-time graph represent?
A positive slope represents positive velocity.
What does a zero slope on a distance-time graph represent?
A zero slope represents zero velocity.
What does a negative slope on a distance-time graph represent?
A negative slope represents negative velocity.
What does a curve on a distance-time graph indicate?
A curve indicates a changing slope, which means a changing velocity.
What happens as the slope of the line on a distance-time graph becomes steeper?
As the slope becomes steeper, the velocity of the object becomes greater.
What are the axes on a distance-time graph?
The x-axis represents time, and the y-axis represents distance.
What does constant speed look like on a distance-time graph?
Constant speed is represented by a straight line with a constant slope.
What does zero speed (at rest) look like on a distance-time graph?
Zero speed is represented by a horizontal line.
What does accelerating (speeding up) look like on a distance-time graph?
Accelerating is represented by a curve with an increasing slope.
