Motion Flashcards
What is the equation for content speed?
Speed (v) = distance travelled (s) / time taken (t)
What is velocity?
Measuring speed in a given direction.
What is displacement?
Is used for the distance travelled in a given direction.
What is the acceleration of an object?
An objects is its change of velocity per second.
What is the equation for acceleration?
Acceleration (a) = change in velocity / time taken for change (t).
How can you write the equation for acceleration?
A = v-u/t
What is another word for deceleration?
Negative acceleration.
What is the gradient of a line?
The gradient of the line on a velocity-time graph represents acceleration.
What does the section of the graph with a horizontal line show on a velocity-time graph?
Constant velocity. The gradient of the line is zero, so the acceleration in this section is zero.
How do you calculate the distance from the velocity-time graph?
The area under the line on a velocity-time graph represents distance travelled in a given direction (or displacement). H
