Balanced and Unbalanced forces

Balanced and Unbalanced forces. Force —a push or pull that acts on an object (can be measured in Newtons) Force-is a vector quantity-it ahs both size or strength, and direction Examples of forces: applied forces, friction, gravity, magnetism, etc.

Presentation Transcript

  1. Balanced and Unbalanced forces • Force—a push or pull that acts on an object (can be measured in Newtons) • Force-is a vector quantity-it ahs both size or strength, and direction • Examples of forces: applied forces, friction, gravity, magnetism, etc.

  2. Net force: the combination of all the forces acting on the object • Net forces can be balanced or unbalanced • When forces are balanced, the net force is zero. (equal forces, but in opposite directions)

  3. Balanced forces: forces that are equal, but in opposite directions • Balanced forces do NOT change the direction of the force • There will be no movement of an object when forces are balanced

  4. Unbalanced forces: when unequal forces are applied in opposite directions (can make an object speed up, or slow down, or change direction) • The greater force will cause the object to move in that direction • NET FORCE-will be the difference between the two forces

  5. When two forces act in opposite directions, the smaller force can be subtracted from the larger to determine the net force • When two forces act in the same direction, they can be added together to determine the net force

  6. Practice calculating Force, using the formula: • F = m X a • Pg. 195
