๐Ÿ“š Quick Study Guide

  • โš–๏ธ Force: A push or pull that can change the motion of an object. Measured in Newtons (N).
  • โžก๏ธ Net Force: The overall force acting on an object. If forces are in the same direction, add them. If they are in opposite directions, subtract them.
  • โ†”๏ธ Balanced Forces: Equal and opposite forces that result in no change in motion (net force = 0).
  • โ†—๏ธ Unbalanced Forces: Unequal forces that cause a change in motion (acceleration).
  • ๐ŸŽ Gravity: The force of attraction between objects with mass. On Earth, the acceleration due to gravity is approximately $9.8 m/s^2$.
  • friction: A force that opposes motion between surfaces in contact.
  • ๐Ÿ“ Formula:** $F = ma$ (Force = mass x acceleration)

๐Ÿงช Practice Quiz

  1. What is a force?
    1. A type of energy.
    2. A push or pull.
    3. A measure of mass.
    4. A state of equilibrium.

    2. Meters per second (m/s).
    3. Newtons (N).
    4. Joules (J).
  3. What happens when balanced forces act on an object?
    1. The object accelerates.
    2. The object changes direction.
    3. The object remains at rest or continues moving at a constant velocity.
    4. The object's mass increases.

    4. A car moving at a constant speed on an icy road.
  6. What does the formula $F = ma$ represent?
    1. Force equals velocity times time.
    2. Force equals mass times acceleration.
