| GESTURE | Motion of hands |
| VELOCITY | A measure of the rate of motion of a body expressed as the rate of change of its position in a particular direction with time |
| DOPPLER | Physicist remembered for his explanation of the apparent change in the frequency of a wavelength caused by the relative motion of the source (7) |
| MOMENTUM | In physics, the quantity of motion of a moving body, equal to the product of the mass and the velocity (8) |
| FREEFALL | Motion of a body, such as a spacecraft, under the force of gravity only; part of a parachute jump before the canopy deploys; or, any fast uncontrolled descent, dip or drop (4,4) |
| DYNAMICS | The science of the motion of bodies and action of forces with them (8) |
| BOBBLE | Word for the oscillating motion of disturbed water or of a floating cork; a pill on the surface of cloth; a pompom for a woolly hat; a tie for a ponytail; or, a bungle, fluff, fudge or fumble (6) |
| BALLISTICS | Study of the motion of projectiles |
| FLAGELLA | Organs of motion of many microorganisms |
| INASECOND | Very quickly part of a motion of support (2,1,6) |
| SUPERMAJORITY | Landslide first observed in motion of Jupiter, Mars and last sign of Mercury (13) |
| PRECESSION | Motion of a spinning body in which it wobbles so that the axis of rotation sweeps out a cone |
| EVECTION | Periodical variation in the motion of the moon caused by the attraction of the sun (8) |
| GAS | Expanding to fill any space, a state of matter whose behaviour, based on the motion of its particles, is explained in the kinetic molecular theory (3) |
| BUSTLE | Word for hurried activity; excited noisy hubbub; a stir or tumult; or, perhaps alluding to the rustling noise or motion of such a fuss, a pad or frame to puff out the back of a skirt (6) |
| ADAMS | Astronomer who explained the origin of the Leonid meteor swarms, described the motion of the Moon and independently calculated Neptune's position, by mathematical rather than observational means (5) |
| SHAKE | Up-and-down or to-and-fro motion of a lamb's tail, milk being frothed or two hands clasped in greeting, e.g. (5) |
| WHIPLASH | A flexible end of a switch or riding crop; or, a jerk or jolt to the neck that occurs suddenly, like the cracking motion of a scourge (8) |
| UPWARDNESS | Rising motion of wasps under churn (10) |
| OTIC | Duck has convulsive motion of the ear |
