If an object is acted upon by an unbalanced force it will be changing its motion - accelerating.
The velocity of an accelerating body is expressed by taking its Initial Velocity and adding to it the Acceleration (the change in velocity) times the period of acceleration.
This is V = V(initial) + A * Time
Example: A car is driving at 28 m/s.... (That's about 60 mph) and accelerates at a rate of 2 m/s/s. After 12 seconds, what is its speed?
V = 28m/s + (2m/s/s*12sec)
V = 52 m/s (That's about...?)

Under constant force, acceleration is constant:

from F=m*a, a= F/m. If m is constant and F is constant, then a is constant.

Under constant acceleration velocity = acceleration x time:

V=a*t

that is the relationship.

actual. Mass*acceleration by way of gravity is comparable to weight. The fee of the burden is comparable to the value of the conventional tension (tension of gravity on merchandise) however the burden and ordinary tension are in separate instructions.
