Chapter P9- Motion Flashcards
What is the equation for speed?
What are the units for each part of the equation?
What can a distance time graph be used to show?
What is always on the y axis on a distance time graph?
What does a flat line show on a distance time graph?
What is always on the x axis on a distance time graph?
What represents speed on a distance time graph?
What a straight line show on a distance time graph?
What does a curved line show on a distance time graph?
Speed= Distance -:- Time
m/s, m, s
A journey
Distance
Stationary
Time
The gradient of the line
A constant speed
Acceleration.
What does a downwards gradient show on a distance time graph?
What is velocity?
What is velocity classified as?
What is the acceleration of an object?
What is the equation to calculate acceleration?
What is deceleration and when is it used?
What are the three units for acceleration?
What are the two units for velocity?
What does a flat line show on a velocity time graph?
What does a downwards straight line show on a velocity time graph?
Direction change towards the starting point
Speed in a given direction
Vector quantity
Its change in velocity per second
Acceleration= Final velocity - Initial velocity -:- time
Negative acceleration so is used in any situation where an object slows down
m/s2 (squared) or m/s/s or ms(to power of)-2
m/s or ms(to power of)-1
Constant velocity
Constant deceleration.
What does the gradient represent on a velocity time graph?
What does a straight line show on a velocity time graph?
Where is distance travelled shown on a speed distance graph?
Acceleration
Constant acceleration
The area under the graph (the x axis).
