What is 'jerk' in the context of an Acceleration vs. Time (AT) graph?
Press to flip
Jerk is the rate of change of acceleration over time (slope of the AT graph).
How do you calculate the change in velocity from an Acceleration vs. Time graph?
The change in velocity is given by the area under the Acceleration vs. Time curve.
How can acceleration be determined from a Velocity vs. Time graph?
Acceleration is determined by the slope of the Velocity vs. Time graph.
What does the slope of a Displacement vs. Time (ST) graph represent?
The slope of a Displacement vs. Time graph represents velocity.
What does a negative slope on a Displacement vs. Time graph signify?
A negative slope signifies motion in the backward direction (negative velocity).
What does a horizontal line on a Displacement vs. Time graph indicate?
A horizontal line indicates zero velocity.
What does a concave downward shape in a Displacement vs. Time graph indicate?
A concave downward shape indicates negative acceleration.
Describe the motion represented by a concave upwards curve on an ST graph.
A concave upwards curve represents positive acceleration.
In a Velocity vs. Time (VT) graph, what does the area under the curve represent?
The area under the curve represents displacement.
In motion graphs, how do you distinguish between speeding up and slowing down?
Speeding up is indicated when velocity and acceleration have the same sign, while slowing down occurs when they have opposite signs.
What does the sign of the slope in a Velocity vs. Time graph indicate about acceleration?
The sign of the slope indicates whether acceleration is positive (speeding up) or negative (slowing down).
What type of graph would you use to determine the rate of change of displacement over time?
A Displacement vs. Time graph is used to determine the rate of change of displacement over time.
How do you interpret a zero slope in a Velocity vs. Time graph?
A zero slope in a Velocity vs. Time graph indicates constant velocity (no acceleration).
How is the velocity calculated from an ST graph between two points?
Velocity is calculated as the slope between the two points: (y2 - y1) / (x2 - x1).
If the VT graph has a constant positive slope, what does this say about the motion?
A constant positive slope indicates uniform positive acceleration.
