The lack of an arrow over this symbol is an indication that speed is a scalar quantity. Both v→ and S are measured with the unit m/s (meters per second) according to the International System of Units (SI). However, as they represent the rate in which a distance (or change in ...
is the speed of light in a vacuum c = 299792 458 metres per second (approximately 1079 000 000 km/h or 671000 000 mph ). Matter cannot quite reach the speed of light, as this would require an infinite amount of energy. In relativity physics, the concept of rapidity replace...
like pushing, energy, speed, and even momentum. in physics, we have a very explicit definition for momentum. the momentum (at velocities not near the speed of light) is defined as the product of the mass and velocity of an object. this definition physicists (and textbooks) agree on. the...
Relative Motion is a physics way of keeping kinematics sane. For example, the earth is actually moving at ridiculously high speeds (from a valid perspective or frame) but since everything on it moves at that same speed, we ignore the speed of the earth and just compare sa...
