resultant forces

• What is the resultant force?

  The total force from all individual forces
• What factors are considered in calculating the resultant force?

  Magnitude and direction of all forces
• What happens when there is a positive resultant force?

  It leads to acceleration in the same direction
• What occurs with a negative resultant force?

  It causes acceleration in the opposite direction
• When are forces considered balanced?

  When the resultant force is zero
• What is the effect of balanced forces on an object's motion?

  They do not change the state of motion
• What happens when forces are unbalanced?

  They cause a change in the state of motion
• How does the resultant force affect an object's motion?

  It determines the object's motion
• What occurs if the resultant force is zero?

  The object remains at rest or moves straight
• What happens if the resultant force is not zero?

  The object accelerates in the resultant force's direction
• What is the equation relating force, mass, and acceleration?

  F = ma
• How do you calculate a resultant force when forces are not parallel?

  Resolve individual forces into components
• How can components of forces be calculated?

  Using trigonometric functions
• How is the resultant force found from components?

  Add or subtract the components considering direction
• What theorem is used to calculate the magnitude of resultant force at right angles?

  The Pythagorean theorem
• How is the direction of the resultant force calculated?

  Using basic trigonometry
