Flashcards in P2 Deck (14):
1

Equation for acceleration

acceleration= (final velocity-inital velocity)/ time taken (v-u)/t

2

Displacement

Distance with direction. It is also the shortest distance between two places

3

Distance

The measure of length with meters as its unit

4

Distance-time graph

a graph with distance on the y-axis and time on the x-axis. The slope represents the speed. Therefore, a horizontal line indicates a stationary object.

5

Rate

a quantity that changes with time

6

Scalar quantity

A quantity with magnitude but without direction. E.g mass, energy, temperature, speed, distance

7

Speed

the rate of change of distance. It is a scalar quality and has the units m/s

8

Equation for speed

Speed=distance/time s=d/t

9

Vector quantity

A quantity with both magnitude and direction. E.g force, displacement, velocity

10

Velocity

Speed with direction. It is a vector quantitiy and has the units m/s

11

Velocity-time graph

A graph with velocity on the y-axis and time on the x-axis. The gradient is a measure of acceleration. The area under the line is equal to how far the object has travelled

12

Equation for velocity

displacement/ time taken

13

Decceleration

when acceleration is negative. Slowing down.

14

Acceleration

rate of change of velocity. It is a vector quantity and has the unit m/s/s
