1. SUVAT Equations and Motion Graphing

• What are the SUVAT equations used for?

  They are used to describe the motion of objects under uniform acceleration.
• What is the formula for final velocity in the SUVAT equations?


  V = u + at
• What does the formula V = u + at represent?

  It represents the final velocity as the initial velocity plus acceleration multiplied by time.
• What is the formula for displacement when using average velocity?


  S = ½ (u + v) t
• What does the formula S = ½ (u + v) t calculate?

  It calculates the displacement as half the sum of initial and final velocities multiplied by time.
• What is the formula for displacement using initial velocity and acceleration?

  S = ut + ½ at²
• What does the formula S = ut + ½ at² represent?

  It represents displacement as the product of initial velocity and time plus half the product of acceleration and time squared.
• What is the formula relating final velocity, initial velocity, acceleration, and displacement?

  V² = u² + 2as
• What does the formula V² = u² + 2as calculate?

  It calculates the final velocity squared as the initial velocity squared plus two times acceleration times displacement.
• What does a distance versus time graph indicate for uniform motion?

  It shows a straight line starting from (0,0) indicating constant speed.
• How is speed represented on a distance versus time graph?

  Speed is given by the gradient of the graph.
• What does a random motion indicate on a distance versus time graph?


  It indicates variable speed, with instantaneous speed given by the gradient at a specific moment.
• What does the gradient of a velocity versus time graph represent?


  The gradient represents instantaneous acceleration.
• What does a velocity versus time graph indicate for uniformly accelerated motion?


  It shows a straight line starting from (0,0) indicating constant acceleration.
• How is instantaneous acceleration determined from a velocity versus time graph?


  It is given by the gradient of the graph at a particular moment in time.
• What does the area under a speed versus time graph represent?


  It represents the distance traveled by an object.
• What does the area under a velocity versus time graph represent?


  It represents the displacement of an object during a time interval.
• How can instantaneous speed be found from a distance versus time graph?


  By calculating its gradient at that moment.
• How can instantaneous velocity be found from a displacement versus time graph?


  By calculating its gradient at that moment.
• How can the instantaneous acceleration of an object be found from its velocity versus time graph?

  By calculating its gradient.
• What are the key points of the SUVAT equations?


  • V = u + at
  • S = ½ (u + v) t
  • S = ut + ½ at²
  • V² = u² + 2as
• What are the characteristics of distance versus time and velocity versus time graphs?

  Distance vs Time Graph:

  • Uniform motion: straight line from (0,0)
  • Random motion: variable speed, gradient indicates instantaneous speed

  
  

  Velocity vs Time Graph:

  • Uniformly accelerated motion: straight line from (0,0)
  • Random motion: variable acceleration, gradient indicates instantaneous acceleration
• How can areas under graphs be interpreted in motion analysis?

  • Area under speed vs time graph: distance traveled
  • Area under velocity vs time graph: displacement
