Question

Describe the motion of the blocks before and after they are knocked down. Also describe the interactions of the blocks with other objects as they are knocked down and fall.

Answer 1

Answer:

Newton’s second law of motion is closely related to Newton’s first law of motion. It mathematically states the cause and effect relationship between force and changes in motion. Newton’s second law of motion is more quantitative and is used extensively to calculate what happens in situations involving a force. Before we can write down Newton’s second law as a simple equation giving the exact relationship of force, mass, and acceleration, we need to sharpen some ideas that have already been mentioned.

Answer 2

The motion is described by the Newton's third law.

• According to  the first statement, it states that there is equal and opposite reaction. That is the cause and its effect.

• When the blocks are knocked down which means there is transfer of energy and momentum in the two body

• These are described as the conservation of the energy and momentum  before and after it remain same.

• In the second statement, there is fall of blocks which shows that here the conservation of momentum does not take place.

• Because the first block has more energy than the second block.
