Speed, Velocity, and Acceleration Concepts

Miss Washington introduces the concepts of speed, velocity, and acceleration. Speed is defined as traveling a certain distance in a specific time, measured in meters per second, miles per hour, or kilometers per hour. Velocity is similar to speed but includes direction, such as '10 miles per hour west.' Acceleration occurs when speed increases or decreases, or when direction changes, like a car speeding up or a biker changing direction. The video provides examples and encourages note-taking for better understanding.

Which of the following is NOT a unit of speed?

• Meters per second

• Miles per hour

• Kilometers per hour

• Meters per minute

How is speed defined?

• Change in velocity over time

• Distance traveled in a specific amount of time

• Distance traveled in a specific direction

• The force applied to an object

What does it mean when speed is described as 'how fast'?

• It refers to the direction of travel

• It indicates the time taken to travel a distance

• It measures the change in speed

• It describes the rate of distance covered over time

What is the primary difference between speed and velocity?

• Speed is measured in miles per hour, velocity in kilometers per hour.

• Speed includes direction, velocity does not.

• Velocity includes direction, speed does not.

• Velocity is always greater than speed.

If a car is traveling at 60 miles per hour east, what is this an example of?

• Distance

• Acceleration

• Velocity

• Speed

Which of the following is an example of velocity?

• 20 miles per hour

• 15 miles per hour west

• 5 kilometers per hour

• 10 meters per second

What happens to acceleration when a car speeds up from 20 mph to 50 mph?

• Acceleration becomes zero

• Acceleration increases

• Acceleration remains constant

• Acceleration decreases

Which scenario is an example of acceleration?

• A plane flying at a constant altitude

• A runner stopping after a race

• A biker turning from north to south

• A car maintaining a constant speed of 60 mph

What is a form of acceleration?

• Moving in a straight line

• Maintaining a constant speed

• Changing direction while moving

• Stopping completely

What should you do after learning about speed, velocity, and acceleration?

• Ignore velocity and acceleration

• Only focus on speed

• Practice problems related to these concepts

• Forget about the concepts
