Flashcards in Distance, Speed, Velocity & Acceleation graphs Deck (14):
What are vectors?
Quantities that have a magnitude (size) and direction.
What are scalars?
Quantities with only a magnitude.
What is displacement?
Measures the distance and direction in a straight line from objects starting point to finishing point. (Vector quantity).
What is velocity?
Speed in a given direction.
What is speed?
How fast you are going with no regard to the direction.
What is distance?
How far an object has moved. (Scalar)
What is acceleration?
How quickly You're speeding up. (Vector)
What is the formula for distance?
Speed x time
What is the formula for acceleration?
(f-i) (change in velocity)
What is the formula for uniform acceleration?
v2 - u2 = 2 x a x d
What is the speed on a distance time graph?
speed=gradient=change in the vertical/change in the horizontal
What are the different parts of a distance time graph?
+ The gradient - gives the speed of an object
+ Flat - object has stopped
+ A steeper graph - object is going faster
+ Curves - represent acceleration
+ Curve getting steeper - object is speeding up
+ Levelling off - slowing down (decreasing gradient)
What are the different parts of a velocity/time graph?
+ Gradient = acceleration
+ Flat - steady speed
+ Steeper the graph - greater the acceleration or deceleration
+ Uphill (/) - acceleration
+ Downhill (\) - deceleration
+ Curve - changing acceleration
