5.6.2 Speed and Velocity

• The formula for calculating speed is distance divided by time
• Speed is a scalar quantity.
• Match the formula with the corresponding quantity:

  Speed ↔️ Distance / Time

  Velocity ↔️ Displacement / Time
• Velocity is defined as how fast an object is moving in a specific direction
• Velocity is a vector quantity.
• What is the key difference between speed and velocity?

  Velocity includes direction
• Speed is a scalar quantity, while velocity is a vector quantity.
• A car traveling at $60 \text{ m / s}$ has a speed of $60 \text{ m / s}$, but its velocity is60 \text{ m / s}</latex> in a certain direction
• What is the formula for calculating speed?

  $\text{Speed} =$$\frac{\text{Distance}}{\text{Time}}$
• The formula for velocity is displacement divided by time.
• A cyclist moves 100 meters North in 10 seconds. What is the cyclist's velocity?

  $10 \text{ m / s North}$
• Speed measures how fast an object moves, while velocity includes speed and direction
• Direction is essential when considering velocity.
• Match the property with the correct quantity:

  Scalar ↔️ Speed

  Vector ↔️ Velocity
• What is the formula for calculating velocity?

  $\text{Velocity} =$$\frac{\text{Displacement}}{\text{Time}}$
• Velocity describes how fast an object is moving in a specific direction.
• To calculate speed, divide the total distance by the time
• A car travels 300 kilometers in 5 hours. What is its speed in km/h?

  $60 \text{ km / h}$
• What is the unit of velocity?

  $\text{m / s}$
• What is the formula to calculate speed?

  $\text{Speed} =$$\frac{\text{Distance}}{\text{Time}}$
• In the speed formula, Distance is the total length traveled
• A car travels 300 km in 5 hours. What is its speed?

  60 km/h
• The car's speed is 60 km/h.
• What is the formula to calculate velocity?

  $\text{Velocity} =$$\frac{\text{Displacement}}{\text{Time}}$
• In the velocity formula, Displacement is the distance traveled in a specific direction
• A cyclist moves 100 meters North in 10 seconds. What is their velocity?

  10 m/s North
• Scalar quantities have only magnitude, while vector quantities have both magnitude and direction
• Match the quantity type with its definition:

  Scalar ↔️ Magnitude only

  Vector ↔️ Magnitude and direction
• Speed is an example of a scalar quantity, while velocity is an example of a vector
• A car travels 240 km in 3 hours. What is the car's speed?

  80 km/h
• A bicycle moves 360 meters East in 40 seconds. What is its velocity?

  9 m/s East
• A plane flies 720 km South in 1.5 hours and then 360 km North in 0.5 hours. Calculate its average speed.

  540 km/h
• A plane flies 720 km South in 1.5 hours and then 360 km North in 0.5 hours. Calculate its average velocity.

  180 km/h South
