Distance, Displacement, and Velocity Concepts

The video tutorial introduces key concepts in motion, focusing on the differences between distance and displacement, and speed and velocity. It explains how distance and speed are scalar quantities, while displacement and velocity are vectors, which include direction. The tutorial also covers how vectors can have negative values, depending on direction, and provides examples to illustrate these concepts.

What is the primary difference between distance and displacement?

• Distance is a vector quantity, while displacement is scalar.

• Distance measures the total path traveled, while displacement measures the change in position.

• Distance can be negative, while displacement cannot.

• Distance is always greater than displacement.

If a person walks 5 meters forward and then 5 meters back to the starting point, what is their displacement?

• 10 meters

• 0 meters

• 5 meters

• 10 meters backward

How is speed defined in terms of distance?

• Speed is distance multiplied by time.

• Speed is distance divided by time.

• Speed is the square of distance over time.

• Speed is the sum of distance and time.

What distinguishes velocity from speed?

• Velocity is measured in meters, while speed is in seconds.

• Velocity is always greater than speed.

• Velocity includes direction, while speed does not.

• Velocity is a scalar quantity, while speed is a vector.

Which of the following is a scalar quantity?

• Velocity

• Acceleration

• Displacement

• Speed

What is the smallest possible value for a scalar quantity like distance?

• Zero

• Negative one

• Negative infinity

• One

What does it mean for a vector to have a negative value?

• The vector is zero.

• The vector has no magnitude.

• The vector is moving in the opposite direction.

• The vector is scalar.

If a car travels 100 meters north and then 100 meters south, what is its total displacement?

• 200 meters

• 0 meters

• 100 meters north

• 100 meters south

Which of the following statements is true about vectors?

• Vectors are the same as scalars.

• Vectors are always positive.

• Vectors can be negative because they include direction.

• Vectors only have magnitude.

In the context of motion, what does a negative velocity indicate?

• The object is stationary.

• The object is moving in the opposite direction to the defined positive direction.

• The object is moving faster than the speed of light.

• The object is moving in a circular path.
