Acceleration is measured in terms of distance per time per time. A typical unit would be meters per second squared. If an object is moving, its speed can be measured in terms of the amount of distance it covers in a given unit of time. And if it is accelerating, that acceleration is the amount of change in speed that takes place in a given unit of time.
You have spelt it correctly in your question. Acceleration is correct.
Not often in ordinary conversation. Its units are meters per second in the international standard, or feet per second in the old Imperial standard.
In (meters/second) / second, usually abbreviated to meters/second2. Or in any other unit of length, divided by a time unit squared (or even two different time units).
velocity is mass times speed
Acceleration is the rate of change of velocity. In other words, it is velocity divided by time. As velocity (in SI) is expressed in metres per second, acceleration must be measured in 'metres per second per second'. In fact, this is the correct way of 'saying' the unit of measurement for acceleration, NOT 'metre per second squared'. The symbol for metres per second per second is 'm/s/s' which, of course, is exactly the same as m/s2 (where 2 is a superscript).
the object's 'velocity'
Acceleration is defined as the change in velocity, divided by the time it takes to achieve this change. There are also some other formulas which you can use, depending on what you know about a specific situation.
Final velocity is the your last velocity traveled. Example if you travel 50m/s your final velocity is 50m/s because its the last velocity traveled, 0m/s is the initial velocity. Its not your total velocity because if u start running at 5m/s then accelerated 25m/s, your final velocity is NOT 30m/s. It is 25m/s. Also, your velocity change is 20m/s(25-5).
The force of gravity opposes acceleration away from the source of the gravity. This is expressed as "centrifugal force" or the perpendicular component of a tangential velocity. The balance between these keeps the planets in orbit around the Sun.
velocity is expressed in m/s
Speed or velocity can be expressed as the distance divided by time.
velocity vector
Velocity is defined as change in positin per time. It is usually expressed in m/s , Km/s . miles per second etc.,
Orbital velocity is the average velocity (or speed) of a planet as it orbits around the sun. It is usually expressed as km/s or mph.
Velocity
metres per second ms-1
There is no synonym to velocity. there is no directionality in velocity. speed is a measure of rotation around a center expressed in revolutions per unit of time. Velocity is a measure of distance in units of time with no direction. Vectors indicate direction.
The momentum is expressed as: p = mv, so assuming the velocity increases, the momentum of the body will increase too.
Vf = Vi + a t
Molecular velocity is defined as the velocity of a each molecule in a certain sample of gas. It can be expressed by means of root-mean-square velocity, average velocity and most probable velocity.
(any unit of length) / (any unit of time) is a unit that can be used for the magnitude (size) of velocity, and must always be accompanied by a description of direction. Without it, all you have is a speed, not a velocity.
