Understanding free fall, fluids, and circular motion

Forces and motion • Speed, acceleration, and laws of motion

Key concepts

What you'll likely be quizzed about

  • Free fall occurs when an object is under the influence of gravity alone, without any other forces acting upon it.
  • The acceleration due to gravity, denoted as g, causes the object to increase its velocity as it descends.
  • Understanding free fall is crucial in analyzing motion in a gravitational field.

What is the relationship between free fall and gravity?

Click to reveal answer

Free fall is the motion of an object under the influence of gravity alone, showcasing gravitational acceleration.

Key notes

Important points to keep in mind

Objects in free fall accelerate at 9.81 m/s².

Fluids exert pressure equally in all directions.

Centripetal force is always directed towards the center of the circular path.
