Because inertia is how someone doesn't want to stop moving. Seatbelts relate by stopping the forward motion. thats right, inertia is an objects tendancy to resist change, seatbelts help to absorb some of the person's inertial energy by stretching a little. meaning the persons slows to a stop over a longer amount of time.
Inertia. This is the word that best defines Newton's first law of motion, which states that an object at rest will stay at rest and an object in motion will stay in motion with a constant velocity unless acted upon by an external force.
Mass is a measure of the amount of matter in an object, while inertia is the tendency of an object to resist changes in its state of motion. Mass and inertia are directly related - objects with more mass have more inertia, making them harder to accelerate or decelerate. The greater an object's mass, the greater its resistance to changes in motion due to its inertia.
because of the gravity of the earth and its rotating movement in science.
An idiot. Would this person deny that there is gravity, or electricity, or chemicals, or almost anything else? After all, what is science? What is his definition of this science that he does not believe in?
We use science, technology and some help from gravity.
many things like inertia gravity etc.
Gravity, inertia, momentum, acceleration, meterology, medicine (for when you crash). Take your pick.
Mass in science refers to the amount of matter in an object. It is a measure of the inertia of an object and is often quantified in units such as kilograms or grams. Mass is a fundamental property of matter and is distinct from weight, which takes into account the force of gravity acting on an object.
making seatbelts and airbags
mass is in science,inertia is in science. there. i feel so proud of myself for thinking up that one
inertia!
Science has been used to create airbags, and seatbelts to make automobiles safer. =)
Inertia. This is the word that best defines Newton's first law of motion, which states that an object at rest will stay at rest and an object in motion will stay in motion with a constant velocity unless acted upon by an external force.
Nothing specifically. Inertia is a proprety of matter (as you may know from the Bill Nye the Science Guy intro), and just because there is more mass to an oject doesn't really mean that it would have more inertia. However, other forces such as friction and gravity are spread over an oject, so there would be more friction due to the mass and more downwards force because of gravity + the mass.
state of an object mass times velocity.
um well i think that science proved that if we are not wearing seat belts, and are in a crash, we could die, or get badly injured. Ages ago, three year olds sat in the front seat without a seat belt, and science shows that it was dangerous and IS dangerous for us to not wear seatbelts.
In science, 'energy' is the ability of matter to overcome inertia and perform work.
