Albert Einstein's formula "E=mc2" means energy equals the mass of an object multiplied by the speed of light squared. His theory means that the mass of an object, no matter how small, can be transformed into a tremendous amount of energy.
Know MoreNuclear energy proves this theory since it uses a small amount of mass and converts it into an enormous amount of energy that can be used to power millions of homes. Some of this energy can even be converted to mass to create a new particle. The speed of light squared is a large number, and it is the secret behind the power of this formula.

Full Answer >Momentum is equal to the mass of an object multiplied by its velocity. The final unit of momentum is equal to the kilogram-meter per second.
Full Answer >For an object with unchanging mass, force equals mass times acceleration. This is abbreviated as f = ma. Force is a push/pull on an object resulting from interactions with another object. Having a magnitude and a direction makes force a vector quantity.
Full Answer >Mass does not affect speed directly, but it does affect how fast an object can change its speed by accelerating or decelerating. Objects with larger masses require more time for acceleration or deceleration compared to lighter objects.
