Physics: Understanding Acceleration

The video tutorial explains the concept of acceleration in physics, defining it as the change in velocity over time. It discusses how changes in the magnitude or direction of velocity can result in acceleration. The tutorial also provides a step-by-step example of calculating acceleration, demonstrating the formula and its application.

What is the definition of acceleration in physics?

• Change in mass over time

• Change in direction over time

• Change in velocity over time

• Change in speed over distance

Acceleration is calculated by dividing the change in velocity by what?

• Change in direction

• Change in distance

• Change in time

• Change in mass

When does velocity change?

• When both magnitude and direction of velocity change

• When the direction of velocity changes

• All of the above

• When the magnitude of velocity changes

What happens to velocity when its direction changes?

• It remains the same

• It changes

• It decreases

• It increases

If a motorbike's velocity changes from 0 to 20 meters per second in 5 seconds, what is its acceleration?

• 5 meters per second squared

• 4 meters per second squared

• 2 meters per second squared

• 3 meters per second squared

What is the unit of acceleration?

• Meters per minute squared

• Meters per second

• Meters per second squared

• Meters per minute
