Inertia is defined as the tendency of a body to preserve its state of rest or uniform motion unless acted upon by an external force.
When a bus at rest starts to move suddenly,the passenger move backward because of inertia of the passenger to remain in the state of rest .
According to Newton's third law of motion, "The single ball on the left will move as high as the ball on the right was dropped" is the expected result once the ball hits the ball closest to it.
Answer: Option A
<u>Explanation:</u>
Newton’s cradle is the best example for law of conservation of momentum. So that means that energy or momentum exhibited by a particle can be transferred to its nearer object with equal force. So in the given options the first option is correct. As when the right ball is dropped it will collide with its neighboring ball and transfer energy.
By this transferring of energy from one particle to another, it will reach the leftmost ball. But there will be no loss in the energy as the left ball will move as high position as the ball on the right was dropped from. So that means the energy is conserved in the cradle.
Answer:
Explanation:
