Question

In the representation of Free body diagram, the only restriction is that all parts of the system show have
a) Identical acceleration
b) Different acceleration
c) Non uniform acceleration
d) No need to consider acceleration​

Answer 1

Answer:

d) No need to consider acceleration

Answer 2

Answer:

In the representation of free body diagram ....d) No need to consider acceleration​.

Explanation:

• Free body diagram: This is a representation of a body at a particular situation with the magnitude and direction of all the forces acting on it.
• Diagram shows only the external forces acting on an object.
• Internal forces of the system are not considered in diagram.
• Velocity and acceleration are not represented on the diagram.
• Example: Suppose an object is falling from a height due to gravity. Then applied forces on the object will be gravitational force(Fg) in downward direction and force applied by air(Fa) in the opposite direction of motion. The free body diagram will be like this:

                                                      ↑ Fa

                                                  Object

                                                       ↓Fg

• In diagram the acceleration is not mentioned. So free fall diagram is excluded acceleration.
