Motion
by Mary Lager
# Motion

## Equations

### V(f)=V(i)+ a(x)t

### Change in x=1/2[V(f)+V(i)]t

### Change in x=V(i)t+1/2at^2

### V(f)^2=V(i)^2+2a(delta)x

## Newton's Second Law

### Force vector = mass scalar time acceration vector

### Net Force is constant

## Acceration

### Linear

### Units

### rate of change in velocity

## Vectors

### Displacement

## Velocity

### Linear

## Net Force

### Constant

### Not Constant

## Free Fall

### No other forces but Gravitational

### Weight

### Acceration is equal to g

### Vector in x direction and y direction

F=ma

Average, Average Velocity/time interval

Instantaneous, Change in velocity/a very small time interval

meters per seconds squared

Average, Change in rate/Change in time

Instantaneous, The displacement/a very small time change

Acceration is Constant

The change in velocity has the same direction as the net force

Mass x 9.8m/s/s

Apparent Weight, Is Zero while in free fall, Less then the Normal Force

Use equations to solve with vector addition
