Question

. Discuss the concepts associated with kinetics. Further, discuss how components of kinetics can influence two movement patterns. Give one example of contact forces and an example of non-contact forces.

Answer 1

#. The concpets associated with kinetics are :-

- mass

the quantity of matter composing a body

- inertia

resistance to action or change

- force

a push or pull on a body

- free body digram

a picture of a structure being analyzed including a representation of all of the active forces

- net force

the sum of all forces acting in the system

- center of gravity or mass

the average position of the weight or mass of a body or object

- weight

the force produced by gravity acting on an objects mass

- load

a force or weight acting on a structure

- pressure

force distributed over a given area

- volume

the amount of space occupied by a body or object

#. Contact force occurs due to the contact between two different objects. Non-contact force occurs due to either attraction or repulsion between two objects such that there is no contact between these objects. Friction is an example of contact force. Gravitational force is an example of non-contact force.
