Hemiplegia or diplegia: One arm and one leg on the same side of the body (hemiplegia) or both legs (diplegia or paraplegia) are affected. These are the most common types of spastic cerebral palsy. Monoplegia: Only one arm or leg is affected. Quadriplegia : Both arms and both legs are affected. Usually the trunk and muscles that control the mouth, tongue, and windpipe are affected too. This makes eating and talking difficult.
The Meaning of Force. A force is a push or pull upon an object resulting from the object's interaction with another object. Whenever there is an interaction between two objects, there is a force upon each of the objects. When the interaction ceases, the two objects no longer experience the force. Forces only exist as a result of an interaction.
In physics, a force is any interaction that, when unopposed, will change the motion of an object. In other words, a force can cause an object with mass to change its velocity (which includes to begin moving from a state of rest), i.e., to accelerate.n physics, a force is any interaction that, when unopposed, will change the motion of an object.
