5.6.2 Speed and Velocity

• What is speed a measure of?

  How fast an object moves
• Velocity is the rate of change of an object's position in a specific direction
• Speed and velocity are identical concepts.

  False
• Velocity calculations include the direction of motion.


  True
• What formula is used to calculate speed?

  Speed = Distance / Time
• Speed is the rate of change of an object's position
• Speed is a vector quantity.

  False
• What is the formula for calculating velocity?

  Velocity = Displacement / Time
• Velocity is a scalar quantity.

  False
• Velocity is a vector quantity, while speed is a scalar
• Velocity is calculated as displacement divided by time
• What are the units of speed and velocity?

  m/s
• Speed is calculated as the distance travelled divided by the time
• What factors are considered when calculating speed?

  Distance and Time
• Specifying units is optional when discussing speed or velocity.

  False
• If an object travels 50 meters in 10 seconds, its speed is 5 m/s
• Velocity is a vector quantity because it includes both magnitude and direction.

  True
• The formula for velocity is Displacement / Time
• Velocity is the rate of change of an object's position in a specific direction
• What type of quantity is speed?

  Scalar
• What is the key difference between speed and velocity?

  Velocity includes direction
• Differences between speed and velocity

  1️⃣ Velocity includes direction

  2️⃣ Speed is a scalar quantity

  3️⃣ Velocity is a vector quantity
• How is speed defined in physics terms?

  Rate of change of position
• Specifying units is necessary for understanding the magnitude of speed or velocity.

  True
• Speed is a vector quantity.

  False
• An object travels 100 meters in 20 seconds. Calculate its speed.

  5 m/s
• The units for both speed and velocity are meters per second
• The formula for displacement is Displacement = Velocity × Time
• What are the three formulas related to speed?

  Speed, Distance, Time
• An object traveling 120 meters south with a velocity of 8 m/s takes 15 seconds.


  True
• What is the formula for calculating velocity using displacement and time?

  Velocity = Displacement / Time
• An object travels 100 meters in 20 seconds. What is its speed?

  5 m/s
• What is the definition of velocity?

  Rate of change of position
• An object has a displacement of 120 meters south in 15 seconds. What is its velocity?

  8 m/s South
• Velocity is a vector quantity.


  True
• Unlike speed, velocity considers the direction
• What are the units for both speed and velocity?

  m/s
• The formula to calculate time is Time = Distance / Speed
• An athlete runs at a speed of 7 m/s for 30 seconds. How far did they run?

  210 meters
• An object has a displacement of 50 meters to the east in 10 seconds. What is its velocity?

  5 m/s East
