Flashcards in Distance, Speed, Velocity & Acceleation graphs Deck (14):
1

What are vectors?

Quantities that have a magnitude (size) and direction.

2

What are scalars?

Quantities with only a magnitude.

3

What is displacement?

Measures the distance and direction in a straight line from objects starting point to finishing point. (Vector quantity).

4

What is velocity?

Speed in a given direction.

5

What is speed?

How fast you are going with no regard to the direction.

6

What is distance?

How far an object has moved. (Scalar)

7

What is acceleration?

How quickly You're speeding up. (Vector)

8

What is the formula for distance?

Speed x time

9

What is the formula for acceleration?

(f-i) (change in velocity)
------
time

10

What is the formula for uniform acceleration?

v2 - u2 = 2 x a x d

11

What is the speed on a distance time graph?

speed=gradient=change in the vertical/change in the horizontal

12

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)

13

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

14

How do you find the distance in a velocity time graph?

Distance = area under graph
