Force |
A force is a push or pull it can be described by direct Shannon and can be combine it is called net force on balanced forces or a net force greater than zero can cause an object to change motion . It can start or stop moving or have a change in direction objects will accelerate in the direction of a greater force . If a force is balanced it will not cause a change in motion . A balanced force has a net force of zero. |
