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

Answer:
1] Newton's law of motion : Explanation with example According to the first law : If an object is at rest/uniform motion it will continue to remain in rest/motion unless and unbalanced force act on it.
Example 1) Pushing a big 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 ship to not come crushing down.
Example : 3) When we shot the bullet in a space it would travel in a straight line until it's 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 shot race at the same speed then bicycle will win the race.
Example : 2) For a long race truck will win race at the because E = ma ( a acceleration is more ).
Example : 3) If a dog is Bulling a rock then acceleration is fully dependent on the force of because the mass of rock will be change.
3] Newton's law of motion : Explanation with examples According to the 3rd law of motion for every action there is an equal opposite reaction.
Example : 1) When we push the floor the floor pushes back.
Example : 2) Car wheel produce friction trying to push & ground exerts an opposite force push it.
Example : 3) Rockets use fuel to push on ground which lifts them up Rockets also rely on friction with alr so that fuel still works.
