Speed, Velocity, and Acceleration

What is the definition of speed given in the video?

• The rate at which something changes its direction

• The rate at which something changes its position

• The distance covered in a specific time

• The time taken to cover a distance

How is velocity different from speed?

• Velocity has no direction

• Velocity is a scalar quantity

• Velocity is a vector quantity

• Velocity is the same as average speed

What are the units commonly used for measuring acceleration?

• Meters per second

• Miles per hour

• Kilometers per hour

• Meters per second squared

What does negative acceleration refer to?

• Speeding up

• Slowing down

• Changing direction

• Constant speed

What does the video suggest about acceleration?

• It can happen when slowing down or changing direction

• It only occurs when speeding up

• It is unrelated to velocity

• It is the same as speed
