  1. Projectile Motion Any object released into the air is termed a projectile.

  2. All projectiles have a flight path and flight time depending on how they are affected by the variables below. • Gravity • Air Resistance • Angle of Release • Speed of Release • Height of Release • Spin

  3. Gravity • Gravity acts on a body to give it mass. • The greater the mass of an object the greater the influence of gravity upon it. • What is the effect of gravity on a projectile? - It decreases the height a projectile can attain.

  4. Gravity

  5. Gravity

  6. Air Resistance • Air resistance acts on the horizontal component of a projectiles path.

  7. Angle of Release • The angle of release of a projectile determines the flight path. • If the angle of release is high, the projectile has a longer flight time but decreased distance. • If the angle of release is low, the projectile has less flight time but increased distance* *However if the angle is too low, distance is poor.

  8. Angle of Release • How is distance and height manipulated in golf for the best shot? - Angle of club head.

  9. Speed of Release • Velocity (speed of motion) of release will determine the size of the flight path. • This is determined by the force summation gathered.

  10. Height of Release • The greater the height of release the greater the distance gained

  11. Spin • There are two main types of spin 1. Top spin- distance is decreased with topspin. 2. Back spin- distance is increased with backspin.

  12. Back Spin • A backspin shot creates a region of low pressure on top of the ball and a region of high pressure below. As a consequence, the ball floats suddenly thereby increasing the distance attained.

  13. Topspin Q. So how does Topspin work? A. A topspin shot creates a region of high pressure on top of the ball and a region of low pressure below. As a consequence, the ball dips suddenly thereby decreasing the distance attained
