The video tutorial introduces the concepts of velocity and speed, explaining their differences and how to calculate them. It covers the equation for velocity, emphasizing the importance of understanding variables. An example problem is solved to find average velocity, highlighting the need for unit conversion. The tutorial concludes with a discussion on speed, noting its lack of direction compared to velocity.

What is the symbol for velocity?

• Delta t

• Upper case V

• Lower case v

• Delta x

What does delta represent in the velocity equation?

• Time

• Distance

• Position

• Change in

What does the variable 'x' stand for in the context of velocity?

• Time

• Position

• Distance

• Speed

What is the complete equation for velocity?

• Velocity = Speed / Time

• Velocity = Displacement / Time

• Velocity = Position final - Position initial / Time final - Time initial

• Velocity = Distance / Time

What two characteristics does displacement have?

• Speed and Direction

• Magnitude and Direction

• Magnitude and Distance

• Magnitude and Speed

In the example problem, what is the change in time?

• Time final - Time initial

• 27 minutes

• 1.89 kilometers

• Delta x

What is the displacement in the example problem?

• Time final - Time initial

• 1.89 kilometers east

• Delta t

• 27 minutes

What is the final answer for the average velocity in the example problem?

• 1.89 kilometers per minute

• 1.166 meters per second

• 1.2 meters per second east

• 1.2 meters per second

What is the equation for speed?

• Speed = Position / Time

• Speed = Velocity / Time

• Speed = Displacement / Time

• Speed = Distance / Time

When do speed and velocity have the same magnitude?

• When the object is stationary

• When the object moves in a straight line

• When the object moves in a circle

• When the object accelerates
