Answer 7

Stationary Objects.

Question 8

Every motion of something, it is relative to something else.

Answer 8

Frame Of Reference

Question 9

How do we know if an object is at motion?

Answer 9

If it changes position relative to it’s frame of reference.

Question 10

The length of path that a moving body travels.

Answer 10

Distance

Question 11

Distance commonly expressed in what?

Answer 11

Meter, Kilometer, Centimeter, and Feet

Question 12

Is Distance a Vector Quantity or Scalar Quantity?

Answer 12

The shortest distance between the initial position and the final position.

Answer 13

Displacement

Question 14

Is Displacement a Vector Quantity or Scalar Quantity?

Answer 14

Vector Quantity

Question 15

Refers to how fast the object is moving.

Answer 15

Speed

Question 16

Speed that is not constant.

Answer 16

Average Speed

Question 17

Speed of the vehicle at the instant while reading the speedometer.

Answer 17

Instantaneous Speed

Question 18

Since speed is _________________________, speed is expressed in terms of the unit of distance and unit of time.

Answer 18

Speed is Distance divided by Time

(Distance / Time = Speed)

Unit for Time?

Answer 20

Second

Question 21

Unit of Speed

Answer 21

Meters per second (m/s)

Question 22

Formula of Average Speed

Answer 22

Average Speed is equal to total distance over total time of travel.
