Question

take 5 example from your surrounding and give explanation based on newtons law of motion no spam​

Answer 1

Answer:

When we walk we push the ground in backward direction with some force. The ground in reaction pushes us forward with the same force. When we shake a tree, the leaves of the tree fall to the ground. This is because the leaves were in the inertia of rest before shaking of tree.

1. Laws of Motion

Answer

1) Newton’s law of motion: Explanation with examples

According to the first law: If an object is at rest/uniform motion, it will continue to remain in rest/motion unless an external unbalanced force act on it.

Example 1: Pushing a big rock, the rock will stay in place until you push it.

Example 2: When a rocket goes up in space, there is almost a perfect amount of earth gravity for the ship to not come crashing down.

Example 3: When we shot the bullet in a space, it would travel in a straight line until it reaches the gravity of another planet.

2) Newton’s law of motion: Explanation with examples

According to 2nd law: The force is directly proportional to the rate of change of momentum.

Example 1: If a truck and bicycle did a short race at the same speed, then bicycle will win the race.

Example 2: For a long race truck will win the race because F=ma and a(acceleration) is more.

Example 3: If a dog is pulling a rock then acceleration is fully dependent on the force of dog because the mass of rock will not change.

3) Newton’s law of motion: Explanation with examples

According to the 3rd law of motion, for every action, there is an equal and opposite reaction.

Example 1: When we push the floor, the floor pushes back.

Example 2: Cars wheel produce friction trying to push and ground exerts an opposite force to push it.

Example 3: Rockets use fuel to push on ground, which lifts them up. Rockets also rely on friction with air so that the fuel still works.
