Hint

1

Distance

The measure of length between objects or points without regard for direction.

New cards

2

Displacement

The change in position of an object.

New cards

3

Vector

A quantity that has direction as well as magnitude.

Example: Displacement, Velocity and Acceleration

New cards

4

Scalar

Quantities that have no direction associated with them.

Example: Distance and Speed

New cards

5

Resultant Vector

The single vector that represents the sum of two or more individual vectors.

New cards

6

Speed

The magnitude of the change of its position per unit of time.

Aka a positive number with units.

New cards

7

Velocity

The magnitude of how fast an object is moving and the direction in which it’s moving.

New cards

8

Acceleration

How rapidly the velocity of an object is changing.

New cards

9

Distance Formula

Distance= Speed x Time

New cards

10

Displacement Formula

Δx= x_{2}-x_{1}

Displacement= Final - Initial

New cards

11

Speed Formula

Speed= Distance Traveled/Time Elapsed

s= d/t

New cards

12

Velocity Formula

v= Δx / Δt

Velocity= Displacement / Time Elapsed

*Average speed is not necessarily equal to the magnitude of the average velocity

New cards

13

Acceleration Formula

a= Δv / Δt

Acceleration= Change in Velocity / Time Elapsed

New cards

14

Positive/Negative Acceleration

Positive= right

Negative= left

The acceleration vector (orange) points to the left because the car slows down as it moves to the right.

New cards

15

Positive/Negative Displacement

Positive Displacement= Right

Example: Δx= 30.0m - 10.0m = 20.0m

Negative Displacement= Left

Example: Δx= 10,0m - 30.0m= -20.0m

New cards

16

Positive/Negative Velocity

The average velocity is positive for an object moving to the right along the *x* axis and negative when the object moves to the left.

**The direction of the average velocity is always the same as the direction of the displacement.*
