The hammer is a 16 lb. implement and is used in outdoor competitions. It is also an Olympic event. The 35 and 56 lb. weights are primarily used indoors. The 35 pound weight is currently an official indoor US Track and Field championship event. The current world record is 84' 10.25" by Lance Deal in 1995. The 56 pound weight was actually an Olympic event in 1904 and 1920. A national champion was crowned until 1959 when it was discontinued, although many meets still held the event. Bob Backus was national champion from 1953 to 1959. While a world record is no longer recognized, any throw over 45' was considered premium. My father, Al Hall, competed in four Olympic games in the hammer throw. He also participated in the weight events for over 30 years, winning 6 national championships in the 35.

The electric field between two plates is directly proportional to the potential difference across them. This relationship is described by the equation E V/d, where E is the electric field, V is the potential difference, and d is the distance between the plates.

The electric field between two plates can be calculated by dividing the voltage difference between the plates by the distance separating them. This formula is represented as E V/d, where E is the electric field strength, V is the voltage difference, and d is the distance between the plates.
In an electric field, the relationship between voltage (e), electric potential difference (v), and distance (d) is described by the equation v e d. This means that the electric potential difference (v) between two points in an electric field is equal to the product of the electric field strength (e) and the distance (d) between the points.
Mass is a measure of the amount of matter in an object and is constant, regardless of the gravitational force acting on it. Weight, on the other hand, is the force exerted on an object due to gravity and can vary depending on the strength of the gravitational field. The numerical difference between mass and weight is that weight is a force and is measured in newtons (N), while mass is measured in kilograms (kg) or grams (g).
Weight is actually force in a fixed setting. In the context of a relatively large and uniform gravitational field (such as being on the surface of the planet), weight is the force along the line between the center of the gravitational field and the center of the object. That is, the weight of an object in such a gravitational field is the strength of that field multiplied by the mass of the object.
