The sum of two vectors is called the

• additional force

• vector force

• resultant force

• equilibrant force

Forces that act on the same point at the same time are called

• equilibrant forces

• concurrent forces

• resultant forces

• vector forces

A single force that can place two or more other forces acting on a single point in equilibrium is called the

• equilibrant force

• resultant force

• concurrent force

• vector force

Any vectors can be resolved into these, which, when added, give a resultant equal to the original vector.

• equilibrium forces

• resultant forces

• component forces

• vector sum forces
