P9 Motion Flashcards
What is the equation for speed?
Speed (m/s) = distance (m)/time (s)
What does it mean if the line is horizontal on a distance - time graph?
The object is stationary
What does it mean if the line is a straight line that slopes upwards on a distance - time graph?
The object is moving at a constant speed
What is the displacement of an object?
The distance travelled in a given direction
What is the velocity of an object?
Its speed in a given direction
What is the equation for acceleration?
Acceleration (m/s2) = final velocity (m/s) - initial velocity (m/s) / time taken for change (s)
What does the gradient of the line on a velocity - time graph represent?
The acceleration
What does the gradient of the line on a distance - time graph represent?
Speed
What does the area under the line on a velocity - time graph represent?
The distance travelled
