Inertia is the tendency of an object to remain at rest or in motion. Newton's First Law of Motion states that an object will remain at rest or move at a constant speed in a straight line unless it is acted on by an unbalanced force. One example of inertia is when you are riding in a car and the driver puts the brakes on. Your seat belt responds by instantly tightening to keep your body in the seat. Inertia is the resistance of any physical object to any change in its state of motion; this includes changes to its speed, direction, or state of rest. This means that the object doesn't want to stop, or doesn't want to go right, so it goes left, or the object will continue in a straight line if the car turns. If at rest, the object won't move unless it is hit with a force. Inertia comes from the Latin word, "iners", meaning idle, sluggish. Examples of inertia: When the bus is running, the whole body of the passenger is in the state of motion. When the bus stops suddenly, the lower part of the passengers body which is in contact with the bus, comes to rest. But the passengers upper portion remains in the state of motion due to the inertia of motion. This is the reason for the passenger to lean forward when the bus stops suddenly. If a person throws a ball vertically upwards in a moving train, it comes back to his hand: The moment the ball was thrown, the ball was also in motion alone with the person who has thrown the ball and the train. This is due to inertia of motion. So when the ball remains in the air, both the person and the ball move ahead by the same distance. This makes the ball to come back to his hand on its return. In a sports field, an athlete often runs before taking a long jump: The reason why an athlete runs before taking a long jump is that the athlete brings himself into a state of motion and so it becomes easier for him to take a long jump. A person jumping out of a moving train, falls down: When the person is sitting inside a train, his complete body was in a state of motion with the train. The moment he jumps out of the moving train, his feet touches the ground, and the lower portion of his body comes to rest. But the upper portion remains in motion due to inertia of motion. That's why he falls in the direction of motion of the train. To avoid this, the person should run in the direction of motion of the train for some distance after he jumps out of the train. Then he will not fall down. I challenge you this weekend...impress your family and friends: Go on, tell them, science is fun!

Wow. I'm so suprised! Barely anyone commented this weekend... My goal with this comment is to get at least 2 pieces of candy. Honestly, I doubt that will happen though. If I do get 2 or more pieces of candy I'll be the happiest little cow in the field.

I have not seen Thor ,my mom tells me that she needs to watch it first so that she can see if it's appropriate for the family. Anyway how as everyone's weekend? I know I am probably going to be the last one commenting. But who cares! I had a really great time! I practically just did ballet but I love doing it! If your like me and you do a lot of something then you should love what you are doing. I have blisters on my feet but that does not stop me from what I ma doing! I sound kind of like my ballet teacher! I hope that everyone had a good as day as I did! It is kind of weird that when you are typing it looks like you are typing a lot but when you actually submit it looks twice as small! Hope everyone has a great day!

Mrs. TaylorI love science! Everything about the world is interesting and never boring. I love to study plants, animals, insects, and people. My favorite subjects are my students who are the most unique organisms on the planet! Categories |
