The video tutorial explains the concepts of speed and velocity, highlighting the differences between them. It covers how to calculate speed as the distance traveled over time, using examples like a physics mobile and an airplane. The tutorial then introduces velocity, which includes both speed and direction, and provides examples of calculating velocity. Formulas for speed and velocity are discussed, emphasizing the importance of understanding the relationship between distance, time, and velocity.

What is the average speed of an object?

• The speed at a specific moment

• The total distance divided by the total time

• The distance covered in one second

• The speed shown on a speedometer

If a car travels 20 meters in 4 seconds, what is its speed?

• 6 m/s

• 5 m/s

• 4 m/s

• 7 m/s

What is the formula for calculating velocity?

• Velocity = Distance * Time

• Velocity = Time / Distance

• Velocity = Speed * Time

• Velocity = Distance / Time

If you know the velocity and time, which formula would you use to find the distance?

• Distance = Velocity / Time

• Distance = Time / Velocity

• Distance = Velocity * Time

• Distance = Speed / Time

A physics mobile moves 40 meters to the right in 5 seconds. What is its velocity?

• 8 m/s to the right

• 7 m/s to the right

• 9 m/s to the right

• 10 m/s to the right

If you know the distance and velocity, which formula would you use to find the time?

• Time = Distance * Velocity

• Time = Distance / Velocity

• Time = Velocity / Distance

• Time = Distance + Velocity

If an airplane has a velocity of 700 m/s to the right, how long does it take to travel 7,000 meters?

• 5 seconds

• 8 seconds

• 10 seconds

• 12 seconds

What is the distance covered by a ball thrown at 20 m/s for 8 seconds?

• 140 meters

• 170 meters

• 150 meters

• 160 meters
