5.6.2 Speed and Velocity

• Speed is a scalar quantity, meaning it has magnitude but no direction.


  True
• Velocity is the rate at which an object changes its displacement
• Velocity is a vector quantity, meaning it has both magnitude and direction.


  True
• Velocity measures the rate at which an object changes its displacement, including direction.


  True
• Arrange the following examples to match the correct quantity:

  1️⃣ Speed: A car travels at 60 mph

  2️⃣ Velocity: A plane flies 600 km/h northeast
• Meters per second (m/s) is a common unit for measuring speed in scientific contexts.


  True
• 1 m/s is equal to 3.6 km/h and 2.237 mph
• Kilometers per hour (km/h) is commonly used for measuring everyday speeds of road vehicles.

  True
• Match the quantity with its unit and abbreviation:

  Speed ↔️ m/s

  Distance ↔️ m

  Time ↔️ s
• If a car travels 100 meters in 5 seconds, its speed is 20 m/s.

  True
• Speed is defined as the distance an object travels per unit time
• Speed is a scalar quantity, while velocity is a vector
• Velocity includes direction, whereas speed does not.


  True
• Match the measurement with the correct term:

  Distance ↔️ Speed

  Displacement ↔️ Velocity
• Speed measures the rate at which an object covers distance
• 1 mph is equal to 1.609 km/h and 0.447 m/s
• Speed is defined as the distance an object travels per unit time
• Velocity is the rate at which an object changes its displacement
• If a person walks 20 meters north in 10 seconds, their velocity is 2 m/s north.


  True
• Speed is the rate at which an object covers distance without considering direction
• Velocity is a vector quantity.


  True
• The speed of an object is the distance it travels per unit time
• Common units for measuring speed include m/s, km/h, and mph
• In the velocity formula, displacement is the distance covered in a specific direction
• Match the quantity with its unit:

  Displacement ↔️ m

  Time ↔️ s

  Velocity ↔️ m/s
• Units for measuring velocity include m/s, km/h, and mph
• Velocity is a vector quantity.


  True
• Speed is a scalar quantity.


  True
• Velocity is a vector quantity.


  True
• Speed does not consider direction
• What is an example of speed?

  A car travels at 60 mph
• What is the formula for calculating speed?

  $\text{Speed} =$$\frac{\text{Distance}}{\text{Time}}$
• The formula for calculating velocity is Velocity = Displacement / Time
• What is the formula for calculating distance using speed and time?

  $\text{Distance} =$$\text{Speed} \times \text{Time}$
• What is the formula for calculating time using speed and distance?

  \text{Time} = \frac{\text{Distance}}{\text{Speed}}</latex>
• If a person walks with a velocity of 2 m/s for 10 seconds, their displacement is 20 meters
• To calculate time using velocity and displacement, the formula is: Time = Displacement / Velocity
• Speed is a scalar quantity, meaning it has magnitude but no direction
• Velocity measures the rate at which an object changes its displacement including both speed and direction.


  True
• What is the formula to calculate velocity?

  $Velocity =$$\frac{Displacement}{Time}$
