Learn how to determine the greatest speed from a velocity graph

The video tutorial explains the relationship between speed and velocity, emphasizing that speed is the absolute value of velocity and does not consider direction. It highlights the difference between speed and velocity, where velocity includes direction, while speed is solely about how fast an object is moving. The tutorial also covers how to calculate speed using the absolute value of velocity and concludes with examples to reinforce the concept.

What is the relationship between speed and velocity?

• Speed is the absolute value of velocity.

• Speed is the direction of velocity.

• Speed is always greater than velocity.

• Speed and velocity are unrelated.

How does speed differ from velocity?

• Speed includes direction, while velocity does not.

• Speed and velocity are both vectors.

• Speed is a vector, while velocity is a scalar.

• Speed is a scalar, while velocity is a vector.

Why is speed considered a scalar quantity?

• Because it has both magnitude and direction.

• Because it is always positive.

• Because it only considers magnitude, not direction.

• Because it is measured in meters per second.

When determining the greatest speed, what should be considered?

• The direction of travel.

• The time taken to travel.

• The absolute value of velocity.

• The distance covered.

If a person is moving to the left at 6 feet per second and to the right at 4 feet per second, what is their greatest speed?

• 0 feet per second

• 4 feet per second

• 10 feet per second

• 6 feet per second
