Weight is measured using a calibrated spring-balance (a newtonmeter). |
|
What piece of equipment is used to measure weight? |
|
|
|
The weight of an object and the mass of an object are directly
proportional. |
|
What is the relationship between the weight of an object and the mass of an object? |
|
|
|
The weight of an object depends on the gravitational field strength at the point where the object is. |
|
What does gravitational field strength depend on? |
|
|
|
Weight is the force acting on an object due to gravity. The force of gravity close to the Earth is due to the gravitational field around the Earth. |
|
What is weight and what causes the force of gravity close to the Earth? |
|
|
|
The weight of an object may be considered to act at a single point
referred to as the object's centre of mass. |
|
What is the name of the single point of an object where the weight is considered to act? |
|
|
|
The weight of an object can be calculated using the equation:
weight = mass x gravitational field strength
W = m g
weight, W, in newtons, N
mass, m, in kilograms, kg
gravitational field strength, g, in newtons per kilogram, N/kg
(In any calculation the value of the gravitational field strength (g) will be given.) |

What equation is used to calculate weight? Include the SI units. |
