Take 5 examples from your surroundings and give explanation based on Newton's laws of motion .
Answers
Answer:
1) Newton’s law of motion : Explanation with examples
According to the first law: If an object is at rest, it 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 a rocket goes 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 travel in straight line until it reaches 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.
Hope this helped u, plz giv it the brainliest
Answer dear
Examples of Newton’s Laws of Motion:
--------------------------------------------------------
1) When a ball is kicked in space, the ball keeps moving in one direction as there is no gravity. The ball stops when it hits an object or pulled by other planet’s gravity.
2) When a fast moving car is hit by some object, like a tree, the car immediately stops but continues to move forward. Airbags are provided to safeguard the driver.
3) Considering that the same amount of force is used to move a car and a truck, the car will move faster than the truck, because car has less mass.

4) To push an empty shopping cart is easy than pushing a cart that is full. This is because, the fully loaded cart is heavy as it has more mass which requires more force to push the cart.
5) Releasing air from the balloon causes the balloon to file up. Thus the opposite reaction.
