Trajectory Of Projectile

Time Left:

1. What is a projectile?

  • An object thrown into space upon which the only acting force is gravity
  • An object that generates its own thrust in the air
  • An object that moves in a straight line without acceleration
  • A stationary object in equilibrium

2. What is a trajectory?

  • The horizontal distance traveled before impact
  • The maximum height reached by an object
  • The straight-line distance between two points
  • The path followed by a projectile under the influence of gravity

3. What role does friction play in a projectile’s trajectory?

  • Friction acts against motion, reducing range and height
  • Friction increases the speed of the projectile
  • Friction has no effect on trajectory
  • Friction provides an upward force

4. How does the formula for projectile motion change when friction is removed?

  • The motion becomes circular
  • The standard equations of motion under constant acceleration apply without air resistance
  • The projectile comes to a stop immediately
  • The motion becomes irregular and unpredictable
