Understanding Acceleration-Time Graphs

What is the primary use of acceleration-time graphs?

• To find the displacement of an object

• To determine the change in velocity

• To calculate the total distance traveled

• To measure the time taken for a journey

In an acceleration-time graph, what does a positive acceleration indicate?

• The object is moving backward

• The object is at rest

• The object is slowing down

• The object is moving forward

How is the area under an acceleration-time graph calculated?

• By subtracting the initial velocity from the final velocity

• By multiplying the base and height

• By adding the initial and final velocities

• By dividing the total distance by time

If an object starts at rest and the area under the acceleration-time graph is 6 m/s east, what does this mean?

• The object is accelerating at 6 m/s² east

• The object is now moving at 6 m/s east

• The object is decelerating at 6 m/s² east

• The object has moved 6 meters east

What happens to the speed of an object if the area under the acceleration-time graph is negative?

• The speed decreases in the opposite direction

• The object comes to a stop

• The speed remains constant

• The speed increases in the same direction
