• D.

An arrow drawn from the origin to an objects position

• E.

A continuous line or curve showing an objects position as a function of time

B. Physical quantity described by a single number (with unit).
Explanation
The correct answer is "Physical quantity described by a single number (with unit)." This is because a scalar quantity is a type of physical quantity that can be described by a single number and does not have a direction associated with it. Examples of scalar quantities include mass, temperature, and time.

Explanation
The correct answer is "Change of position." Displacement refers to the change in position of an object over a certain period of time. It is a vector quantity that indicates both the magnitude and direction of the change in position. This term is often used in physics to describe the motion of an object, as it focuses on how the object's position has changed rather than the specific path it took to get there.

### Position vs Time graph

• A.

Has a continuous line or curve showing an objects position as a function of time

• B.

Has a continuous line or curve showing the objects time as a function of position

A. Has a continuous line or curve showing an objects position as a function of time
Explanation
The correct answer is that a Position vs Time graph has a continuous line or curve showing an object's position as a function of time. This means that the graph represents how the position of the object changes over time. The x-axis represents time, while the y-axis represents the object's position. By looking at the graph, one can determine how the object's position changes at different points in time.

### Average Acceleration can be calculated as...

• A.

(distance)/ (time interval)

• B.

(change of velocity)/ (time interval)

• C.

(time interval)/ ( change of velocity)

• D.

(time interval)/ (distance)

B. (change of velocity)/ (time interval)
Explanation
The correct answer is (change of velocity)/ (time interval). Average acceleration is defined as the change in velocity divided by the time interval. It measures how quickly the velocity of an object changes over a given period of time. By calculating the difference in velocity and dividing it by the time interval, we can determine the average rate at which the velocity is changing.
