Understanding Acceleration

What is delta v in the context of acceleration?

• The initial velocity of a body

• The change in velocity of a body

• The time interval between two events

• The final velocity of a body

How is delta t defined?

• The difference between final and initial time

• The average speed over time

• The product of velocity and time

• The sum of initial and final velocities

In the car journey example, what was the initial velocity of the car?

• 20 m/s

• 10 m/s

• 0 m/s

• 5 m/s

What was the final velocity of the car in the city?

• 20 m/s

• 10 m/s

• 15 m/s

• 0 m/s

How long did it take for the car to reach the city?

• 5 seconds

• 10 seconds

• 3 seconds

• 7 seconds

What does an acceleration of 4 m/s² indicate?

• The car's velocity increased by 4 m/s every second

• The car traveled 4 meters every second

• The car's velocity decreased by 4 m/s every second

• The car's velocity remained constant

In the deceleration example, what was the initial velocity of the car?

• 50 m/s

• 30 m/s

• 15 m/s

• 0 m/s

What is the final velocity of the car at point B?

• 0 m/s

• 10 m/s

• 20 m/s

• 30 m/s

What does a negative acceleration value signify?

• The car is stationary

• The car is slowing down

• The car is moving at a constant speed

• The car is speeding up

What is the term used for negative acceleration?

• Acceleration

• Momentum

• Deceleration

• Velocity
