Distance and Displacement

• What is distance in physics?

  How far an object moves
• Does distance involve direction?

  No, it does not involve direction
• What type of quantity is distance?

  Scalar quantity
• What does displacement include?

  Distance and direction of movement
• What is displacement in physics?

  Vector quantity measuring distance and direction
• If a car travels 25 miles east, what is its displacement?

  25 miles east
• What is speed in physics?

  Scalar quantity measuring how fast an object moves
• Is speed constant for moving objects?

  No, it can vary
• How does the speed of walking compare to running?

  Walking speed is slower than running speed
• What is a typical walking speed?

  1.5 m/s
• What is a typical running speed?

  3 m/s
• What is a typical cycling speed?

  6 m/s
• What factors affect a person's speed while walking or running?

  Age, terrain, fitness, and distance
• What is the speed of sound in air?

  330 m/s
• What is velocity in physics?

  Speed in a given direction
• What type of quantity is velocity?

  Vector quantity
• How does an object traveling in a circle maintain velocity?

  It has a constant speed but changing direction
• How does changing direction affect velocity?

  It changes the velocity even if speed is constant
• What happens to velocity when an object travels in a circular path?

  Velocity changes due to changing direction
• What is the relationship between speed and velocity?

  Speed is a scalar; velocity is a vector
• How does the velocity of an object change when it moves in a straight line?

  It remains constant if speed is constant
• What is the effect of changing speed on an object's velocity?

  Changing speed alters the velocity
• What is the typical speed of a car traveling around a circular track?

  Constant speed but changing velocity
• What is the significance of velocity in motion?

  It indicates both speed and direction
• How does the velocity of a satellite differ from that of a car?

  Satellite velocity is constant in orbit
• What happens to an object's velocity when it accelerates?

  Velocity increases in the direction of acceleration
• What is the formula for calculating velocity?

  Velocity = distance / time
• How does the direction of an object's movement affect its velocity?

  It determines the vector nature of velocity
• How does velocity relate to displacement?

  Velocity is displacement over time
• What is the effect of gravity on an object's velocity?

  Gravity accelerates the object downward
• What is the typical velocity of a satellite in orbit?

  Constant velocity in a circular path
• How does the velocity of a thrown ball change?

  It decreases due to gravity acting on it
• How does the velocity of a car differ from that of a bicycle?

  Cars generally have higher velocities than bicycles
• What factors can change an object's velocity?

  Force, mass, and direction of movement
• What is the formula for calculating speed?

  Speed = distance / time
• How does acceleration affect velocity?

  Acceleration changes the velocity over time
• How does the velocity of a moving object relate to its path?

  Velocity indicates the direction of the path
