Q

Linear velocity is

A

The change in portion that occurs in a specific period of time (rate of change in postion)

17
Q

The formula for linear velocity is

A

V= triangle p/ triangle t

18
Q

Speed is the scalar or vector equivalent to velocity

A

Scalar

19
Q

The formula for speed is

A

Speed= distance/ triangle t

20
Q

The unit used for speed is

A

Meters per second (m/s)

21
Q

Linear acceleration is

A

The change in velocity that occurs in a specific period of time (rate of change in velocity)

22
Q

When there is no change in velocity; this means acceleration is

A

Zero

23
Q

The equation fur linear acceleration is

A

A=triangle v/ triangle t

24
Q

The unit of measure for acceleration is

A

Meters per second squared (m/s^2)

25
Q

Finding acceleration on a graph you will use

A

Rise over run
