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 2^{nd} 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 3^{rd} 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.
