.one's body movement to the side when a car makes a sharp turn.
.tightening of seat belts in a car when it stops quickly.
1. Falling of fruits and leaves.
2.Falling forward while getting down from a moving bus.
3.The continued swirling of milk after the stirring is stopped.
1.It’s due to the inertia of rest. Before shaking, the branch is at rest, but when the tree is shaken, the branch starts moving, whereas the fruits and the leaves remain in their initial state of rest. Thus, they fall down.
2.This is again due to the inertia of motion. When a passenger gets down from a moving bus, their upper body is still in motion, and when it comes in contact with the ground which is at rest, their body topples forward due to the inertia of motion.
3.It is due to the magic of inertia of motion, which keeps the milk moving inside the glass.
If pulled quickly, a tablecloth can be removed from underneath the dishes. The dishes have the tendency to remain still as long as the friction from the movement of the tablecloth is not too great.
If a stopped car is hit by a moving car from behind, the passengers inside may experience whiplash as a result of the body moving forward but the head lagging behind. The head is experiencing inertia.
A balloon in a car will appear to move when the car moves forward, but the balloon is actually attempting to stay in the place it was, it is only the car that is moving.
When a car is abruptly accelerated, drivers and passengers may feel as though their bodies are moving backward. In reality, inertia is making the body want to stay in place as the car moves forward.
If an index card is placed on top of a glass with a penny on top of it, the index card can be quickly removed while the penny falls straight into the glass, as the penny is demonstrating inertia.
When pulling a Band-Aid off, it is better to pull it fast. Your skin will remain at rest due to inertia, and the force pulls the Band-Aid off.
experiments or activities to conduct to find inertia:
·try putting a piece of cloth under one book, when you remove the cloth the book will fall because it has less force but if you put a stack of books you will see that the books did not fall because they have greater force and the more force means there is more inertia and inertia is the ability of an object to resist motion, and so the books resisted motion
Law of Inertia
1) If you roll a ball, it will continue rolling unless friction or something else stops it by force.
2) A balloon in a car will appear to move when the car moves forward, but the balloon is actually attempting to stay in the place it was, it is only the car that is moving.
Law of Acceleration
1) We are in a car and pushing down the gas pedal, so we are accelerating.
2) A football tends to travel in the direction of the line of action of the force of a kick, at a speed directly proportional to the force and inversely proportional to the mass of the football.
Law of Action
1) A swimmer swimming forward: The swimmer pushes against the water (action force), the water pushes back on the swimmer (reaction force) and pushes her forward.
2) The ball puts a force on the wall (action force), and the wall puts a force on the ball (reaction force) so the ball bounces off.
