Physics Measurement and Graphing Quiz

What is a motion diagram?

• A series of images showing the positions of a moving object at equal time intervals.

• A single image showing the position of a moving object.

• A graph representing the speed of an object over time.

What is the purpose of a coordinate system in motion?

• To measure the distance and time.

• To give the location of the zero point of the variable being studied.

• To represent the speed of an object.

What does the length of a displacement vector represent?

• The distance the object was displaced.

• The time taken for the displacement.

• The speed of the object.

What are scalars?

• Quantities that have magnitude only.

• Quantities that have both magnitude and direction.

• Quantities that are always positive.

What is the formula for displacement?

• △x = xf - xi

• △x = xi - xf

• △x = xf + xi

What is the difference between distance and displacement?

• Distance is a scalar quantity, while displacement is a vector quantity.

• Distance can be negative, while displacement cannot.

• Distance measures the shortest path, while displacement measures the total path traveled.

How does acceleration relate to velocity?

• Acceleration is the rate of change of velocity over time.

• Acceleration is the same as velocity.

• Acceleration measures the distance traveled by an object.

What is the significance of the origin in a motion graph?

• It represents the starting point of the motion.

• It indicates the maximum speed of the object.

• It shows the direction of the motion.

What is the unit of measurement for displacement?

• Meter (m)

• Second (s)

• Kilogram (kg)

How is average velocity calculated?

• Average velocity = total displacement / total time

• Average velocity = total distance / total time

• Average velocity = final velocity - initial velocity
