zul actually have to write this post because zul see many friends did not wear seat belt, i have my friends died because involve in accident, my friend from the technic school and there are 2 person died because thrown out during accident happen,her friends try to overtake the express bus,but he turn to left lane too early,so the car, spinning and hit the divider and that 2 person died because thrown out from the car. the body did not have many bleading but since she hit at the head and cause the injury to her
Inertia is a tendency of all objects and matter in the universe to stay still, or, if moving, to continue moving in the same direction, unless acted on by some outside force. This forms the first law of motion formulated by Isaac Newton (1642-1727). To move a body at rest, enough external force must be used to overcome the object's inertia; the larger the object is, the more force is required to move it
that means all the time we do something, there are force tend to fight the direction of the force with exact force we produce, still dont understand? too technical? see the example below
when we do the experiment above, when we move the card, the coin still in that position and then goin inside the glass, its the same thing when we moving in the car when moving and stop suddently,like accident occur. there are the some force of inertia tend to make people inside moving, same thing with the coin but its more dangerous because we have the weight of people and weight of car with high velocity of car and can causes death to the passenger
haha jgn bli baju nih lak
For the car crash scenario where a car stops in 1 foot from a speed of 30 mi/hr, what is the force on the driver? Assume a 160 lb (mass = 5 slugs) driver.
If firmly held in non-stretching seatbelt harness: Stopping distance 1 ft.
can my felow friends imagine to get as many 12tonns of force of impact during accident occur and the car only travel about 50km/hour? how about u drive faster and not wearing seatbelt?
