Acceleration

The video tutorial explains acceleration, measured in meters per second squared, as the change in velocity over time. It provides an example where a vehicle accelerates to 44 meters per second in 4 seconds, resulting in an acceleration of 11 meters per second squared. The concept of deceleration, or negative acceleration, is also introduced when an object slows down.

What is the unit of measurement for acceleration?

• Meters per second squared

• Kilometers per hour

• Miles per hour

• Meters per second

How is acceleration calculated?

• By adding velocity and time

• By multiplying velocity by time

• By dividing the change in velocity by the time taken

• By dividing velocity by time

If a vehicle reaches a speed of 44 meters per second in 4 seconds, what is its acceleration?

• 10 meters per second squared

• 11 meters per second squared

• 12 meters per second squared

• 13 meters per second squared

What term is used to describe negative acceleration?

• Acceleration

• Velocity

• Momentum

• Deceleration

What happens to an object when it experiences deceleration?

• It speeds up

• It maintains its speed

• It slows down

• It changes direction
