• Whenever two bodies interact, the forces they exert on each other are equal and opposite.
• A number of forces acting on a body may be replaced by a single force which has the same effect on the body as the original forces all acting together. The force is called the resultant force.
• If the resultant force acting on a stationary body is zero the body will remain stationary.
• If the resultant force acting on a moving body is zero the body will continue to move at the same speed and in the same direction.
