Physics Quiz 1.1 A

Which of the following best defines a frame of reference in the context of motion?

• The total distance an object travels

• The point or object from which position and motion are measured

• The speed at which an object moves

• The direction of an object's velocity

What is the main difference between distance and displacement?

• Distance is a vector; displacement is a scalar

• Distance is the shortest path; displacement is the total path traveled

• Distance is the total path traveled; displacement is the straight-line change in position

• Distance and displacement are always equal

Which of the following quantities is a vector?

• Speed

• Distance

• Displacement

• Time

If an object has a negative velocity, what does this indicate about its motion?

• The object is slowing down

• The object is moving in the opposite direction to the positive reference direction

• The object is at rest

• The object is speeding up

Given a motion map with equally spaced dots along a straight line, what can you infer about the object's motion?

• The object is accelerating

• The object is moving at constant velocity

• The object is at rest

• The object is changing direction

A car moves 10 meters east, then 5 meters west. What is the car's displacement?

• 15 meters east

• 5 meters east

• 5 meters west

• 15 meters west

Which mathematical model correctly represents the relationship between velocity, displacement, and time for constant velocity motion?

A runner jogs 100 m north, then 60 m south in 40 seconds. What is the runner's average velocity? (Assume north is positive.)

What does velocity measure?

• Total distance traveled

• Displacement per time

• Time per displacement

• Acceleration per time

 Jermaine runs exactly 2 laps around a 400 meter track. What is the displacement?

• 800
• 400
• 0
• 200
