Resultant Forces | GCSE Physics Practice Questions
A resultant force is a single force that has the same effect as all the original forces acting together.
What happens to motion when forces are balanced?
What is Resultant Forces | Practice Questions?
"The single force that represents the sum of all forces acting on an object."
What is the resultant force on an object if a 10N force acts right and a 4N force acts left?
Which of these is a vector quantity?
Which law relates resultant force, mass, and acceleration?
Resultant Force Rules
If resultant force is zero, the object is stationary or moving at constant speed.
If non-zero, the object must be accelerating.
Forces are vectors (they have direction).
Exam Trick: If an object is "moving at a constant velocity", the resultant force is ZERO.
