Question

What is the mass formula in relation with force, energy, momentum?

Answer 1

1. The mass of an object is the quantity of substance it contains. It is a numerical representation of inertia.
2. The SI unit of mass is kg
3. Mass is a scalar quantity.
4. Mass is a constant value for an object.

Different formulas can be used to calculate the object's mass:

1. Equation relating the force $\left(F\right)$, mass $\left(m\right)$, and acceleration (acceleration) $\left(a\right)$ $F=ma$
2. Equation relating the mass $\left(m\right)$, volume $\left(v\right)$ and density$\left(\rho \right)$ is $\rho =\frac{m}{v}$
3. Equation relating the mass $\left(m\right)$ , velocity $\left(v\right)$ and kinetic energy(K.E) is $K.E=\left(\frac{1}{2}\right)m{v}^2$
4. Equation relating the potential energy (PE), mass $\left(m\right)$, gravity $\left(g\right)$ and height $\left(h\right)$ is $P.E=mgh$
5. Equation relating the Einstein’s mass-energy is $E=m{c}^2$ where mass $\left(m\right)$ and velocity light in air medium $\left(c\right)$
6. Equation relating the momentum $\left(p\right)$, mass $\left(m\right)$ and velocity $\left(v\right)$ is $p=mv$
