WebA particle placed in a force field will experience a force acting upon it. This can be represented as a vector. The vector will have direction which depends upon the nature of the object at the point in the field (for example what charge it has). WebThe force in this case is the weight of the object = mg (the object's mass x the gravitational field strength = the object's weight) The distance moved is the vertical distance as this is the direction in which the force of gravity acts - the vertical distance it …
