Physics P2 - Balanced forces

?

Falling objects increase their speed as they fall because their weight (the force of gravity) pulls them to Earth. They also experience air resistance, a frictional force that slows them down.

Objects fall faster until they reach their terminal speed, which is reached when the upward (air resistance) and downward (weight) forces are equal

Terminal Velocity

  • 1. When the skydiver jumps out of the plane he accelerates due to the force of gravity pulling him down
  • 2. As he speeds up the…
