# [Answer] Isla’s change in velocity is 30 m/s and Hazel has the same change in velocity. Which best explains why they would have different accelerations?

The velocity of an object is the rate of change of its position with respect to a frame of reference and is a function of time. Velocity is equivalent to a specification of an object’s speed and direction of motion (e.g. 60 km/h to the north). Velocity is a fundamental concept in kinematics the branch of classical mechanics that describes the motion of bodies.

Sat Aug 16 2003 14:30:00 GMT-0400 (Eastern Daylight Time) · The faster the relative velocity the greater the time dilation between one another with the rate of time reaching zero as one approaches the speed of light (299 792 458 m/s ). Theoretically time dilation would make it possible for passengers in a fast-moving vehicle to advance further into the future in a short period of their own time.

In classical theories of gravitation the changes in a gravitational field propagate. A change in the distribution of energy and momentum of matter results in subsequent alteration at a distance of the gravitational field which it produces. In the relativistic sense the “speed of gravity” refers to the speed of a gravitational wave which as predicted by general relativity and confirmed by …

Velocity definition. i like the definition in terms of velocity : I sp = V e ( m/s ) because it intuitively relates to the physics of propulsion. engines with higher specific impulse are able to eject reaction mass at a higher velocity e.g. ion engines have V e ~ 30 km/s whereas chemical rockets have V e ~3 km/s. — Preceding unsigned comment added by 67.122.137.191 04:25 18 November 2004 (UTC)
