What is the definition of a reference point in the context of describing an object's position?

• The final point an object reaches after movement

• The starting point used to describe the location of an object

• A point that changes as the object moves

• The most distant point visible from the object

Which of the following is NOT a component necessary for a complete position description?

• Distance

• Weight

• Direction

• Reference point

What is the difference between distance and displacement?

• Distance is the total movement of an object, displacement is the object's change in position.

• Distance and displacement both refer to the total path length traveled.

• Distance refers to how fast an object moves, while displacement refers to the direction.

• There is no difference; both terms can be used interchangeably.

How is speed defined in physics?

• The rate of change of velocity per unit of time

• The distance covered per unit of time

• The rate of change of position per unit of time

• The displacement divided by the time taken

What does a distance-time graph primarily illustrate about an object's motion?

• The object's color changes over time

• The object's motion over time

• The object's temperature changes over time

• The object's size changes over time

How is average speed calculated according to the distance-time graph analysis?

• Total distance divided by total time

• Total time divided by total distance

• Change in distance minus change in time

• Change in time minus change in distance

What does the slope of a distance-time graph indicate?

• Changes in color

• Changes in size

• Changes in speed

• Changes in temperature

What is the definition of velocity?

• The speed and size of an object

• The speed and weight of an object

• The speed and direction of an object

• The speed and color of an object

What does acceleration measure?

• The change in velocity over time

• The change in speed over distance

• The change in direction over time

• The change in weight over time

How is acceleration calculated?

• Change in velocity divided by the time interval

• Change in time divided by the velocity

• Change in distance divided by the time interval

• Change in speed divided by the distance interval
