Question

give 5 examples of real life action and reaction force ??​

Answer 1

Explanation:

• Explanation:
• \underline{\underline{\bold{\mathsf{Plaster \:of \:paris }}}}
• Plasterofparis
• :—
• ◽In short it is also called as P.O.P.
• ◽Its chmeical name is calcium sulphate hemihydrate
• ◽The half molecule of water is attached with calcium sulphate.
• ◽It is a white powdery which is slightly hydrated calcium sulfate
• ◽\implies{\mathsf{ CaSO_4 \times \frac{1}{2}H_2 O \:or\: 2CaSO_4 \times H_2O }}⟹CaSO
• 4
• ×
• 2
• 1
• H
• 2
• Oor2CaSO
• 4
• ×H
• 2
• O
• ◽Plaster of Paris is the most commonly used plaster round the world and is also called gypsum plaster.
• ◽Gypsum is a colorless or white substance found near paris and is not highly water-soluble and is not at all hard.
• ◽A mixture of gypsum and water which is poured and as the the water evaporates. gypsum hardens.
• ◽Its given the name "plaster of paris" because of its preparation from the abundant gypsum found near Paris.

Answer 2

Answer:

Newton’s Third Law of Motion states, “When one object exerts a force on a second object, the second one exerts a force on the first that is equal in magnitude and opposite in direction.”

Newton’s Third Law of Motion states, “When one object exerts a force on a second object, the second one exerts a force on the first that is equal in magnitude and opposite in direction.”This law is sometimes called the “Law of Action and Reaction”.

Even though the forces are equal in magnitude (strength) and opposite in direction, they do not cancel each other. This law addresses two objects, each with only one force exerted on it.

Each object is exerting one force on the other object.

Each object is experiencing only one force.

The action and reaction forces are reciprocal (opposite) on an object.

Examples may include:

A swimmer swimming forward:

The swimmer pushes against the water (action force), the water pushes back on the swimmer (reaction force) and pushes her forward.

A ball is thrown against a wall:

The ball puts a force on the wall (action force), and the wall puts a force on the ball (reaction force) so the ball bounces off.

A person is diving off a raft:

The person puts a force on the raft (action force) pushing it, and the raft puts a force on the diver (reaction force) pushing them in the opposite direction.

A person pushes against a wall (action force), and the wall exerts an equal and opposite force against the person (reaction force).

The Space Shuttle engines push out hot gases (action force), and the hot gases put a force on the shuttle engines (reaction force) so the shuttle lifts (there is no sling shot doing it!)
