TOPIC 2- MOTION AND FORCES

• What is the correct def for velocity?

  Speed in a stated direction
• How do you calculate the gradient of a velocity time graph?


  Rise over run- meaning change in velocity over change in time
• First law

  An object will not change its motion unless a force acts on it
• Second law

  The force on an object is equal to its mass times its acceleration
• Third law

  When two objects interact, they apply forces to each other of equal magnitude and opposite direction
• Velocity is

  speed with direction
