- 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...
Mass in modern physics has multiple definitions which are conceptually distinct, but physically equivalent. Mass can be experimentally defined as a measure of the body's inertia, meaning the resistance to acceleration (change of velocity) when a net force is applied.
Jun 11, 2024 · Mass, in physics, quantitative measure of inertia, a fundamental property of all matter. It is, in effect, the resistance that a body of matter offers to a change in its speed or position upon the application of a force. Mass is measured in units of kilograms.
