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?
Which one of the following is an example of Second Class Lever?
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
Consider a journey by a car represented by the graph given below in three parts A, B and C. The speed of the car in these parts is Va, Vb and Vc, respectively:

Which one of the following is correct in this case?
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:
