Question

1) How does a person move forward during swimming? 2) How does walking and running on the ground is become possible? 3) Show with example that action and reaction are equal and opposite?​

Answer 1

He uses the body support such as his hands and legs to move forward


Walking and running is possible on the ground because of friction between the two bodies


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.

IF IT HELPS YOU

LETS START

Q1- HOW DOES A PERSON MOVE FORWARD DURING SWIMMING

ANSWER- ITS DUE TO FORCE APPLIED BACK AND INTERMOLECULAR SPACE BETWEEN THE PARTICLES THAT A SWIMMER IS ABLE TO MOVE FORWARD

Q2-HOW IS WALKING AND RUNNING POSSIBLE ON GROUND

ANSWER- WALKING AND RUNNING ARE POSSIBLE ON GROUND DUE TO FRICTION

WHEN WE MOVE FORWARD WE APPLY THE FORCE BACKWORD AND FRICTION PUSH US IN FORWARD DIRECTION AS FRICTION IS ALWAYS IN THE OPPOSITE DIRECTION OF FORCE APPLIED

Q3-SHOW THAT ACTION AND REACTION ARE EQUAL

ANSWER- ACTION AND REACTION ARE EQUAL ACCORDING TO NEWTONS 3RD LAW OF MOTION

TAKE THE EXAMPLE OF A ROCKET

IT APPLIES FORCE IN DOWNWARD DIRECTION AND HENCE IT MOVE UPWARDS

THIS IS DUE TO NEWTONS THIRD LAW OF MOTION- WHICH SAYS ACTION AND REACTION ARE EQUAL
