Take 5 examples from your surroundings and give explanation based on Newtons laws of motion.

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.
