### Distance and Displacement

## Distance

__Definition:__A scalar measure of the interval between two locations measured along the actual path connecting them.

__My Definition:__ A measure between two locations, measuring the connecting line.

__Formulas__: ∆x= Vₒt + ½a(t*t) (t squared) Displacement

__General Info: __

- Never negative
- It will always increase
- Magnitude

## Displacement

__Definition:__A vector measure of the interval between two locations measured along the shortest path connecting them.

__My Definition:__ A quantity having direction and magnitude, especially in determining the position of one point in space relative to another. Measured along the shortest path connecting them.

__Formulas:__V2= Vₒ(squared) + 2a∆x Displacement with No Time

∆x= Vₒt + ½a(t*t) (t squared) Displacement

__General Info:__

- It is a point of reference
- Can be negative
- Change in Position
- Involve Space
- Magnitude

## Sample Questions

2. A rocket shoots up an altitude of 180.0 km if the initial speed is 3.00 km/s how long did it take the rocket to reach its maximum height?

3.The average speed of a runner is 518 km/h. He decreased his speed from 100% to 40% of his average speed during the interval of 2 min. What is the distance traveled during that interval?

4.A radioactive kitten runs at a speed of 2.60 m/s. By the time the kitten finds his food his speed decreases at 2.20 m/s. If it took him 9.00 min and has a constant deceleration, what is the distance traveled by the super kitten?
