Learn the difference between mass and weight, how they are measured, and how they relate to each other. Find out what is weightlessness and how it affects astronauts in space.
- Mass can be stated as the measure of the quantity of matter in an object. The SI unit of mass is the kilogram (kg).
- Weight is the measure of the force of gravity acting on a body.The formula for weight is given by: w = mg
- Technically, weight is the mass of a body multiplied by the acceleration due to gravity.
- Weightlessness is a condition of free-fall in which the gravity is cancelled by the inertial force arising from orbital flight or other gravity-neg...
- This law is a quantitative explanation of the changes that a force can generate in a body’s motion. The second law states that when a body encounte...

In science and engineering, the weight of an object, is the force acting on the object due to acceleration of gravity. [1] [2] [3] Some standard textbooks [4] define weight as a vector quantity, the gravitational force acting on the object. Others [5] [6] define weight as a scalar quantity, the magnitude of the gravitational force.

noun. the amount or quantity of heaviness or mass; amount a thing weighs. Physics. the force that gravitation exerts upon a body, equal to the mass of the body times the local acceleration of gravity: commonly taken, in a region of constant gravitational acceleration, as a measure of mass. a system of units for expressing heaviness or mass:
