What is acceleration and its si unit?
Acceleration is the rate of change of velocity - how fast a velocity changes. Therefore, its units are naturally (meters/second) / second, usually written as meters/second2.Acceleration is the rate of change of velocity - how fast a velocity changes.

How do you describe derived units?
Derived units are made by combining base units using mathematical operations such as multiplication and division. They are used to express physical quantities and their combination is necessary to represent more complex measurements, such as velocity or volume. Examples of derived units include meters per second for velocity or cubic meters for volume.
What are the units associated with mass x velocity?
Momentum is defined as mass times velocity, and it requires units of mass times units of velocity. The SI unit is kilograms x meters / second. There is no special name for this combination of units. Impulse (force times time) has the same units.
Why the time twice in unit acceleration?
Time squared appears in the unit of acceleration because acceleration is the rate of change of velocity with respect to time. Velocity is measured in units of distance over time, so when you take the rate of change of velocity with respect to time, you have distance over time squared. This is why acceleration is often measured in units like meters per second squared (m/s^2).
What are the units for average velocity?
The units for average velocity are distance divided by time, typically expressed as meters per second (m/s) or kilometers per hour (km/h).
What is a rate of motion in a given direction?
Velocity, the units are meters per second, or feet per second.
SI units for time length speed and velocity?
The SI unit for time is seconds (s), for length is meters (m), for speed is meters per second (m/s), and for velocity is also meters per second (m/s).
What is the standard units of velocity?
The standard unit of velocity is meters per second (m/s).
What are the SI units for length speed and velocity?
The SI unit for length is the meter (m), for speed is meters per second (m/s), and for velocity is also meters per second (m/s).
What is the unit for change in velocity?
In SI units, changes in velocity, or in other words the acceleration, gets measured in meters per second per second, or m/s^2.
Is velocity and acceleration measured in the same units?
No, velocity is typically measured in units like meters per second (m/s), while acceleration is measured in units like meters per second squared (m/s^2). This difference reflects the distinct physical quantities they represent - velocity being the rate of change of position and acceleration being the rate of change of velocity.
What are two common units for velocity?
-- miles per hour north -- meters per second tangential
