Action and reaction forces are exerted on which bodies during an interaction?
Two different bodies
Newton's third law of motion states that for every action, there is an equal and opposite reaction.
These action and reaction forces always act on two different bodies, never on the same body, which is why they do not cancel each other out.
This law applies universally to any interacting bodies, whether at rest or in motion.
Hence, action and reaction forces are exerted on two different bodies during an interaction.
What will be the resultant force if a body of mass 10 kg is moving with an acceleration of 5 m/sec2?
A box initially at rest is pushed with a force of 30 N to the right while friction applies a force of 30 N to the left. What happens to the motion of the box?
A uniform meter scale of mass 0.24 kg is made of steel. It is kept on two wedges, W1 and W2 , in a horizontal position. W1 is at a distance of 0.2 m from one of its ends, while W2 is at distance of 0.4 m from the other end. If the force on the scale is N1 due to W1 and N2 due to W2, then : (take g =10·0 m s-2
Rocket works on the principle of:
A rocket is launched to travel vertically upward with a constant velocity of 20 m/s. After travelling for 35 seconds, the rocket develops a snag and its fuel supply is cut off. The rocket then travels like a free body. The height achieved by it is:
According to Newton's third law of motion, mark the correct option.
1. Action and reaction act on different bodies and so they can be cancelled out.
2. The internal action and reaction forces between different parts of a body do, however, sum to zero.
If Force (F), velocity (V) and time (T) are taken as the fundamental dimensions, instead of mass, length and time, what will be dimensions of linear Momentum (P) ?
