8.4.1 (V-T) (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 velocity-time (V-T) graph represent?
A velocity-time graph shows an object’s velocity as a function of time.
What does a horizontal line on a velocity-time graph indicate?
A horizontal line indicates constant velocity.
What does a straight sloped line on a velocity-time graph represent?
A straight sloped line represents constant acceleration.
How is acceleration calculated?
Acceleration is the change in velocity over time.
What does a positive slope on a velocity-time graph represent?
A positive slope represents positive acceleration.
What does a negative slope on a velocity-time graph represent?
A negative slope represents negative acceleration.
What do different slopes on a velocity-time (V-T) graph indicate about acceleration?
Positive slope = Positive acceleration
Zero slope = Zero acceleration
Negative slope = Negative acceleration
What does the area under the curve on a velocity-time (V-T) graph represent?
The area under the curve to the Y-axis represents the displacement of the object.
How can the area under the curve on a velocity-time graph be found?
The area can be found using simple geometry formulas.
What does the area under the velocity-time graph represent?
The area under the velocity-time graph gives the displacement of the object for the specified time interval.
What does the velocity-time graph look like for constant acceleration?
The velocity-time graph for constant acceleration is a straight line.
What does the slope of a velocity-time (V-T) graph represent?
The slope of a velocity-time graph represents acceleration, which relates to the acceleration formula.
What does a horizontal line on a velocity-time (V-T) graph indicate?
A horizontal line on a velocity-time graph means constant velocity.
What is the velocity of an object that isn’t moving?
If an object isn’t moving, its velocity is zero.
What does a positive slope on a velocity-time graph indicate?
A positive slope indicates the object is undergoing acceleration in the positive direction.
