Centrifugal governors respond to angular velocity. Inertia governors respond to angular acceleration.
that an object at rest will remain at rest Inertia explain many common events. For example, if you are in a car that stops suddenly,inertia causes you to continue moving forward
If you are driving/riding in a car at 40 mph, you are moving along with the car at 40mph also. Due to inertia, you will continue to move at 40 mph unless another force acts upon you, such as your seat belt. Say the car stops moving- you won't due to inertia, but the seat belt will stop you because it is another force.
The law of 'Inertia'.
Inertia keeps them moving forward.
Inertia affects passengers on a bus when it starts suddenly by giving them a jolt and causing the passengers to move forward or backward depending on the buses position.
Inertia keeps you moving forward.
In a car accident your body has a certain amount of momentum and it wants to keep moving forward. The seat-belts slow the body down enough so they don't hit the wind-shield or dashboard etc.
Your feet are pushing backward against the floor, where friction prevents that backward motion and exerts an equal force that pushes you forward. If the floor were not fixed in place, it would move backward instead and you would stay in the same place. If friction did not exist, your foot would merely slide backward across the floor, and again you would stay in the same place.
Inertia is the resistance of an object to change it state of rest or motion. when you are standing in a moving bus and it suddenly stops you tend to fall backward. This is due to inertia of motion. Body resists the change in motion due to which u fall backward. so inertia exactly opposes or resists your change in motion.
In physics, inertia means that though the car is brought to a sudden stop, the person inside will continue in a forward motion. A seat belt would restrain the person's forward movement and prevent the person being injured by the dashboard, or by being thrown through the windscreen. Air-bags are used in modern cars to also cushion against the effect of inertia.
Inertia can hurt you, because it is the force of moving forward. For example, if you throw a ball, inertia "pushes" the ball forward, and could hit the person you threw it too!
'The car's inertia carried it forward several feet after the driver pushed the brakes.' 'His inertia launched him forward after reaching the base of the hill.'
The answer, in short, is INERTIA. Inertia is resistance to changes in motion, and is proportional to mass. Newton's 1st Law of Motion tells us that objects in motion will remain in motion (in a straight line) unless acted upon by an external force. In the example given, the passengers (objects) pitch forward when the driver hits the brakes in a forward-moving car (providing the external force) because their bodies possess inertia separate from the inertia of the moving car. The car slows down due to the braking, but the passengers' separate inertia(s) will cause them to keep moving forward until restrained by an outside force (seatbelt, dashboard, windshield, etc.) Larger, heavier passengers will pitch forward with more force (inertia is proportional to mass, remember?).
It's because of inertia. You are not falling backward technically, rather the bus' acceleration is moving it forward however your inertia is stopping you from moving. So the bus is moving forward while you remain still. It is like the trick when someone pulls a cloth from under a bowl of water very quickly. The cloth comes away cleanly and the bowl does not budge. By the way inertia is the resistance an object (here the object is the passenger in the bus) has to having its state of motion change (that is in this case the passengers are resisting changing their movement from being still to actually moving).
If you were to jump sideways from a train (not that it would be smart), you should roll forward because of inertia which is an objects tendency to resist a change in motion. Since the train is moving forward and you are in it you technically are moving with the train. To slow yourself and not get hurt you must work with inertia.
Inertia explains the feeling of getting pushed back in your car seat as the car begins to accelerate because as the car accelerates your body want to resist the forward motion the car is 'pulling' you in. Inertia is the tendency of an object to resist motion.
