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.
