Flashcards in Quiz one intro chapter and chapter 1 Deck (26):

1

## What is biomechanics

### the study of forces and their effects on living systems

2

## What is the goal of biomechanics

### improve performance and prevent injury

3

## If the goal of biomechanics is to improve performance and prevent injury how can we help with that

### improve equipment and improve training

4

## What is the international system of units

### metric system

5

## What are the three things that we measure in biomechanics

### length, mass, time

6

## how do we measure length, mass, and time

### length- meters, mass- kilogram, time- seconds

7

## 1 kg weighs

### 2.2 lbs

8

## What is inertia

### resistance to change in motion

9

## A newton =

### kg x m/s^2

10

## What is a newton

### the amount of force required to accelerate 1 kg- mass per second

11

## non-contact no contact force gravity weight equation

###
w=mg

g- acceleration due to gravity= 9.81 m/s^2 down

12

## contact equation

###
F= u x R

F- friction

u- coefficient of friction

R- normal contact force (N)

13

## what to do to get the sum of 2 forces

### add them together to get resultant force

14

## how many meters in a yard

### .91 m

15

## how many meters in one mile

### 1609

16

## what is the normal contact force

### reaction to another force

17

## mass times gravity is

### Newton

18

## 1N =

### 1 kg x m/s^2

19

## when see mass think

### kg

20

## when see weight think

### N

21

## when see inertia think

### mass

22

## how many feet in 1 meter

### 3.3ft

23

## how many kilometers in one mile

### 1.6

24

## If have free body diagram of something in kg

###
1. Change it to newtons

2. look of equation

3. plug it in

4. solve

25

## who is the important man

### Issac Newton
