kinematics can be defined as a sub-discipline in physics aimed at understanding the motion of objects without considering the forces that move them.
- Classical mechanics refers to a physical theory that describes the motion of objects.
- Kinematics can be considered a branch of classical mechanics that studies the motion of objects but without considering the forces that move them.
- Kinematics describes the motion of objects and systems by using different types of information such as diagrams, numbers, equations and/or graphs.
In conclusion, kinematics is a sub-discipline in physics aimed at understanding the motion of objects without considering the forces that move them.

Answer:
Explanation:
The weight of some mass is defined as the product of mass by gravitational acceleration. In this way using the following formula we can find the weight.
where:
w = weight [N]
m = mass = 0.06 [kg]
g = gravity acceleration = 10 [N/kg]
Therefore:
By Hooke's law we know that the force in a spring can be calculated by means of the following expression.
where:
k = spring constant [N/m]
x = deformed distance = 6 [cm] = 0.06 [m]
We can find the spring constant.
Since we use the same spring on the moon and the same mass, the constant of the spring does not change, the same goes for the mass.
Since this force is equal to the weight, we can now determine the gravitational acceleration.
