What is your mass in kilograms? Answer in units of kg. A suitcase measures 1.0 m x 0.5 m x 0.2 m and has a mass of 10 kg. What is its weight in newtons? If a cow's mass is 391kg, and a car's mass is 425kg, what is the differe...

The force of gravity acting on an object is also that object's weight. When you step on a scale, the scale reads how much gravity is acting on your body. The formula to determine weight is [source: Kurtus]: weight = m x g where m is an object's mass, and g is the acceleration...

Velocity: Physical quantities can be classified as scalar or vector quantities. A scalar quantity is fully described by just its magnitude or size. For example, distance traveled by a body or the mass of a boy. It is sufficient to say the car traveled 20 {eq}km {/eq} or the mass of...

Velocity and speed are often used interchangeably in everyday language, however there is a distinction in physics. Velocity is a vector, which means it has magnitude and direction. It is calculated using displacement, which is the straight line distance from start to finish...
where \(\Phi\) is the internal friction angle and \({n}_{2}\) is the Manning coefficient of the lower layer. In the equations, on the right side, the first term significantly influences the current velocity of the soil mass, while the second term determines the cessation of soil mass...
What happens inside the black hole is unknown; even our current theories of physics do not apply in the vicinity of a singularity. Even though we cannot see a black hole, it does have three properties that can or could be measured: Mass Electric charge Rate of rotation (angular momentum) ...
aIt is a monumental work for its uniquely poetic embodiment of American democratic ideals. Most of the poems in it sing of “en-mass” and the self as well. 它是巨大的工作为它美国民主理想的独特地诗具体化。 大多诗在它唱歌“en大量”和自已。[translate] ...
