What does displacement indicate in kinematic definitions?

• The total distance an object has covered during its motion.

• The time it takes for an object to return to its initial position.

• How far an object ends up from its initial position, regardless of its total distance traveled.

• The speed of an object at a specific moment in time.

How is average velocity calculated?

• It is the speed of an object at a specific moment in time.

• It is the total distance traveled divided by the time interval.

• It is the displacement divided by the time interval over which that displacement occurred.

• It is the slope of a position-time graph.

What does the slope of a position-time graph represent?

• Acceleration

• Instantaneous speed

• Average velocity

• How far an object is from the detector

What does a position-time slope like a front slash (/) indicate about the object's motion?

• The object is moving toward the detector.

• The object is moving away from the detector.

• The object's velocity is constant.

• The object's acceleration is zero.

What can be determined from the area between the velocity-time graph and the horizontal axis?

• The acceleration of the object.

• The instantaneous velocity of the object.

• How far the object travels.

• How far from the detector the object is located.

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

• Displacement

• Distance from the detector

• Speed

• Acceleration

Acceleration tells how much an object's speed changes in what time frame?

• One minute

• One hour

• One second

• One day

When an object speeds up, its acceleration is in the direction of what?

• The object's initial position

• The direction opposite to motion

• The direction of motion

• A fixed reference point

Objects in free fall gain or lose how much speed every second?

• 5 m/s

• 9.0 m/s

• 10 m/s

• 15 m/s

What is the unit of acceleration?

• m/s

• m/s²

• km/h

• m²/s
