2acceleration — The rate of change of velocity or speed. Velocity is steady and is measured in distance per time (e.g., feet per second, miles per hour, kilometres per hour). Acceleration keeps increasing and is measured in velocity per time (e.g., feet per… …
3acceleration stress — ▪ physiology Introduction physiological changes that occur in the human body in motion as a result of rapid increase of speed. Rapid acceleration and surges in acceleration are felt more critically than are gradual shifts. Pilots are… …
4acceleration — n. 1 the process or act of accelerating or being accelerated. 2 an instance of this. 3 (of a vehicle etc.) the capacity to gain speed (the car has good acceleration). 4 Physics the rate of change of velocity measured in terms of a unit of time.… …
5Tidal acceleration — is an effect of the tidal forces between an orbiting natural satellite ( i.e. a moon), and the planet (called the primary) that it orbits. It causes a gradual recession of a satellite in a prograde orbit away from the primary, and a corresponding …
6Peak ground acceleration — (PGA) is a measure of earthquake acceleration on the ground and an important input parameter for earthquake engineering, also known as the design basis earthquake ground motion (DBEGM)[1] Unlike the Richter and moment magnitude scales, it is not… …
7Proper acceleration — [Edwin F. Taylor John Archibald Wheeler (1966 1st ed. only) Spacetime Physics (W.H. Freeman, San Francisco) ISBN 0 7167 0336 X] is the physical acceleration experienced by an object. It equals the rate of change of proper velocity with respect to …
8Angular acceleration — is the rate of change of angular velocity over time. In SI units, it is measured in radians per second squared (rad/s2), and is usually denoted by the Greek letter alpha ({alpha},). Mathematical definition The angular acceleration can be defined… …
9Equations for a falling body — Under normal earth bound conditions, when objects move owing to a constant gravitational force a set of dynamical equations describe the resultant trajectories. For example, Newton s law of universal gravitation simplifies to F = mg , where m is… …
10Nordström's theory of gravitation — In theoretical physics, Nordström s theory of gravitation was a predecessor of general relativity. Strictly speaking, there were actually two distinct theories proposed by the Finnish theoretical physicist Gunnar Nordström, in 1912 and 1913… …
