Question

In the following situations identify the agent exerting the force and the object on which it acts. State the effect of the force in each case.
Squeezing out juice from an orange

Answer 1

Hint: In physics, a force is any influence that, when unopposed, causes an object to change its velocity. A force can cause a mass item to change its velocity (which includes starting to move from a standstill), i.e. accelerate. Intuitively, force may be characterised as a push or a pull. A force is a vector quantity since it has both magnitude and direction.

Complete Step By Step Answer:
Forces, with the exception of gravity and electromagnetic fields, are always "contact forces," meaning they must physically touch an item in order to exert their impact. Forces also require an agent, which means you should always be able to tell what is causing the force (the agent). Forces are vectors, which means that their strength (push or pull) can be directed in any direction. The Newton is the SI unit of force, and it is represented by the letter N.
The force might be applied by a machine (electric power) or a person. The orange is the item on which the force is operating. The force is causing the orange to move and change its form.
Getting the juice out of an orange by squeezing it between your fingers.
The agent is fingers in the given condition.
The object in question is a lemon.
The impact of the muscular effort produced by the fingers on the orange is the expulsion of lemon juice by squeezing.

Note:
Because forces are experienced as pushes or pulls, an intuitive grasp of how to describe forces may be gained. The intuitive knowledge of forces, like other physical concepts (such as temperature), is quantified using exact operational definitions that are compatible with direct observations and compared to a standard measuring scale.
