You have a right idea of uniform motion; but it would be more correctly expressed by saying, that the motion of a body is uniform when it passes over equal spaces in equal times.
It is mathematically demonstrable, that, in moving round a point towards which it is attracted, a body passes over equal areas, in equal times.
The radius vector (or line joining sun and planet) sweeps out equal areas in equal times.
If it were a material substance, to which the law of gravitation applied, it must be moving in a conic section with the sun in one focus, and its radius vector must sweep out equal areas in equal times.
The equinoctial, therefore, is peculiarly adapted to this purpose, since, in the daily revolution of the heavens, equal portions of the equinoctial pass under the meridian in equal times.
Thirdly, the motion to which a body naturally tends is uniform; that is, the body moves just as far the second minute as it did the first, and as far the third as the second; and passes over equal spaces in equal times.
The radius vector of the earth, or of any planet, describes equal areas in equal times.
The picture-diagram on the bottom illustrates the second law, which is that, as the planet moves round the sun, its radius vector describes equal areas in equal times.
Philosophers,” replied her father, “call the motion of a body uniform, when it passes over equal spaces in equal times.
And, by the same argument, if the circumsolar planets were supposed to be let fall at equal distances from the sun, they would, in their descent towards the sun, describe equal spaces in equal times.
The second is, that the radius-vector, or imaginary line joining the centre of the planet and the centre of the Sun, describes equal areas in equal times.
Every planet moves round the Sun in a plane orbit, and the radius-vector, or imaginary line joining the centre of the planet and the centre of the Sun, describes equal areas in equal times.
This he explained in his next great discovery by proving that an imaginary line, or radius-vector, extending from the centre of the Sun to the centre of the planet 'describes equal areas in equal times.
S to the moving body (being lengthened or shortened in each position to suit its distance from S), this string, as the body moved along AE, would sweep over equal triangular areas in equal times.
A circle having this centre was called the equant, and he supposed that a radius drawn to the sun from the excentric passes over equal arcs on the equant in equal times.
His second law (a far more difficult one to prove) states that a line drawn from a planet to the sun sweeps over equal areas in equal times.
Thirdly, That sound moves over equal spaces in equal times, from the beginning to the end.
And thus as to the Line of Projection, in which (secluding the Resistance) the Motion is reputed uniform; dispatching equal Lengths in equal Times.
In the revolution of a planet round the sun, the Radius Vector describes equal areas in equal times.
This law states that the Radius Vector describes equal areas in equal times.
Still less was he able to offer a reason why these bodies should sweep over equal areas in equal times, or why that third law was invariably obeyed.
A B C be equal to that included in A D E, then a planet would pass from B to C and from D to E in equal times.
This comes about from the property of bodies which act as springs, of which we have spoken above; namely that whether compressed little or much they recoil in equal times.
The above list will hopefully provide you with a few useful examples demonstrating the appropriate usage of "equal times" in a variety of sentences. We hope that you will now be able to make sentences using this group of words.
