take 5 examples from your surroundings and give explanation based on newton's laws of motion
Answers
Answer:
1) Travelling in a bus to another city
2) 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.
5) cycle not starts when we not put force to it
Answer:
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.
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.
