Take 5 examples from your surroundings and give explanation based on Newtons laws of motion.
1) Newton’s law of motion : Explanation with examples
According to the first law: If an object at rest will remain in rest ,in motion will remain in 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 sends rocket up in space, there is almost a perfect amount of earth gravity for ship to not come crashing down.
Example 3. When we shot the bullet in a space, it would be keep in straight line until it either reached gravity of another planet.
2) Newton’s law of motion : Explanation with examples
According to 2nd law: The force is directly proportional to 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 force of dog because 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.
