Assuming no air resistance

• What happens to vertical velocity in projectile motion without air resistance?

  It changes due to the acceleration of free fall.
• How can vertical displacement and time of flight be determined in projectile motion?

  Using equations of motion.
• What happens to horizontal velocity in projectile motion without air resistance?

  It remains constant.
• What are the key characteristics of projectile motion assuming no air resistance?

  • Vertical velocity changes due to free fall acceleration.
  • Vertical displacement and time of flight can be calculated using equations of motion.
  • Horizontal velocity remains constant.
• What is the horizontal component of motion when it is equal to zero?

  Horizontal competed = 0
• Why does the horizontal component of motion remain constant?

  Because there is no force acting in the horizontal direction
• What is the direction of acceleration in free fall?

  Vertical direction
• What remains constant even though there is acceleration in free fall?

  The horizontal velocity remains constant
• What can we always measure in relation to motion?

  We can always measure distance
• What equipment can be used to measure time and distance in experiments?

  Simple lab equipment such as a timer and a ruler
• What is the relationship between horizontal speed and distance?

  • There is a direct relationship
  • As distance increases, horizontal speed increases
  • No force acts in the horizontal direction
• How do you calculate the horizontal velocity of a ball?

  By measuring the distance and time
• What is the formula for calculating distance in horizontal motion?

  The formula is $d =$$vt$, where $v$ is velocity and $t$ is time
• What is the significance of having no force in the horizontal direction?

  It means the horizontal velocity remains constant
• What should you do to analyze the motion of an object?

  Take some values and plot them into a graph
• What is the purpose of using a ruler in motion experiments?

  To measure the distance traveled by the object
• What is the first step in calculating horizontal velocity?

  Measure the distance
• What does the term "latinsia" refer to in the context of motion?

  It likely refers to the concept of distance or displacement
