P9(Motion) Flashcards
The gradient of a line on a distance time graph represents…
speed
The distance time graph for any object that is:
-stationary,is a horizontal line
-moving at constant speed, is a straight line that slopes upwards
What is the formula for speed
What is acceleration
It’s an objects change of velocity per second
What is the formula for acceleration
What is deacceleration
The change of velocity per second when an object slows down
The gradient of the line on a velocity time graph…
Represents acceleration
If a velocity time graph is a horizontal line then…
The acceleration is zero
A positive gradient on a velocity time graph represents …
Positive acceleration
A negative gradient on a velocity time graph represents
deceleration
The area under the line on a Velocity time graph…
Represents distance travelled
